That dry rattle on a cold morning — that is your 2008 Accord’s engine waiting for oil that drained out of the filter overnight. A bad oil filter lets grit and metal shavings grind your engine down, and the wrong one can leak or rattle loose on the road. This guide picks filters that actually fit the M20 x 1.5 thread, seal tight with the right gasket, and catch dirt so your next 5,000 miles stay quiet.
I’m Min Islam — the founder and writer behind Trending Car. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
We looked at thread pitch (M20 x 1.5), bypass valve pressure (the pressure at which a clogged filter lets oil bypass itself to protect your engine), and media type to find the 08 honda accord oil filter that keeps your V6 or four-cylinder running clean without leaking or rattling loose.
Our Picks at a Glance
How To Choose The Best 08 Honda Accord Oil Filter
Your 2008 Accord uses a spin-on oil filter with a specific thread size (M20 x 1.5 — that is 20mm wide with 1.5mm between threads) and gasket diameter. Picking the wrong one means a leak — or the filter backing off while you drive. Here is what to check before you click buy.
The Anti-Drain Back Valve
When you shut off the engine, oil drains out of the filter unless a valve holds it in place. A silicone anti-drain back valve keeps the filter full so your Accord’s bearings get oil the instant you crank it — crucial for cold starts that otherwise sound dry for a split second.
Filtration Media and Capacity
Cheap filters use basic cellulose paper that clogs quickly. Better filters use a synthetic blend or full synthetic media that traps smaller particles — down to 20 microns (20 millionths of a meter, about the width of a strand of spider silk) — while letting oil flow freely. Look for numbers like “up to 14 grams of dirt” or “99% efficiency” to gauge how much crud the filter can hold before it goes into bypass mode (the safety mode where unfiltered oil flows around the clogged media).
Build Quality and Sealing
A steel base plate prevents the filter from deforming under the 15-20 PSI (pounds per square inch) of oil pressure your Accord generates. A nitrile or silicone gasket creates the leak-proof seal. Check reviews for “no leaks” and “easy to remove at next change” to avoid a stuck filter.

In‑Depth Reviews
1. BOSCH 3323 Premium Oil Filter With FILTECH Filtration Technology
Our pick — over 4.5★ from 5,500+ verified ratings; the strongest balance of quality and price.
The canister that catches 14 grams of dirt before your engine ever sees it
The Bosch 3323 holds up to 14 grams of contaminants in its FILTECH media (a synthetic blend designed to trap particles smaller than a human hair) before it clogs. That is a big jump from basic filters — they usually clog sooner and go into bypass mode, sending unfiltered oil to your bearings and cylinder walls. For your Accord’s oil pump pushing at steady pressure, this means grit stays trapped for the full 5,000-mile change interval.
The silicone anti-drain back valve is a standout for cold mornings. Unlike rubber valves that harden over time, silicone stays flexible and seals tight, so oil stays in the filter after shutdown. Buyers report it is a “Perfect fit for my 2005 Honda Pilot,” noting the steel base plate prevents warpage and leaks. One reviewer noted it “felt slightly loose before tightening” but seated securely — the high-lubricity gasket design makes removal at the next change easy without a wrench fight.
At 6.4 ounces, the Bosch 3323 is lighter than the ECOGARD S4610 (9.12 ounces). The lighter weight comes from smart material choices, not weak construction. The metal spiral-wound center tube reinforces internal strength so the canister does not collapse under pressure. It covers a wide range of Hondas — including Accord, Civic, CR-V, Pilot — plus Acura, Nissan, and Infiniti models, so one size fits multiple cars in your driveway.
What Shines
- FILTECH synthetic media traps up to 14 grams of contaminants
- Silicone anti-drain back valve keeps oil ready at startup
- Steel base plate resists warpage at high pressure
The Trade-Offs
- Single pack only — need to buy multiples for a 2-car household
- A few owners note it feels slightly loose before final tightening
Reach for this if: you want the strongest dirt-holding capacity (14 grams) for standard 5,000-mile change intervals without paying the dealer premium.
Look elsewhere if: you prefer buying a 3-pack to stock up or want a filter explicitly rated for 10,000-mile synthetic oil intervals.
2. ECOGARD S4610 Spin-On Engine Oil Filter for Synthetic Oil
Built for synthetic oil and the longer intervals that come with it
If you run full synthetic in your 2008 Accord and stretch changes to 7,500 or 10,000 miles, the ECOGARD S4610 is designed to keep up. Unlike the Bosch 3323 rated for standard intervals, the ECOGARD’s synthetic-blend media has high filtration capacity and screens out up to 99% of dirt and particles. That includes carbon, sand, dust, and metal fragments that build up over extended service intervals.
At 9.12 ounces, it is heavier than the Bosch 3323 (6.4 ounces), which reflects a denser canister and more media inside. The silicone anti-drain back valve (where required by OEM spec) supports lubrication at startup — a key feature for the Accord’s V6 that can be noisy on a cold crank with a drained filter. One first-time DIY buyer mentioned, “I recently changed my oil myself for the first time, this filter came highly recommended,” noting it “went in with zero issues.” The package dimensions are compact: 3.7 x 3.1 x 2.7 inches, so it fits easily in tight engine bays.
The ECOGARD replaces a long list of popular part numbers — FRAM PH7317-S, Wix 51356XP, STP S7317XL — which tells you it is engineered to the same physical dimensions. The 1-year warranty from Premium Guard Inc. covers defects, though shipping costs apply if you need to file a claim. It fits your Accord’s 2.4L (2003-2017) plus the CR-V, Pilot, and Odyssey, making it a solid choice if you also maintain a second Honda.
What Stands Out
- Rated for service intervals up to 10,000 miles with synthetic oil
- Up to 2X the filtration capacity of a conventional filter
- Screens out up to 99% of dirt and particles
The Downsides
- Slightly bulkier at 9.12 ounces vs competitor filters
- Only 236 reviews so far — less long-term data than the Bosch pick
Go with this one when: you use synthetic oil and want a filter that lasts the full 10,000-mile interval without clogging early.
Pass if: you stick to conventional oil at 3,000-mile changes — the higher capacity is more filter than you need.
3. Non-OEM 15400-PLM-A02 Replacement Oil Filter 3-Pack
Three filters in one box for the household that runs multiple Hondas
If you maintain more than one Honda — say a 2008 Accord and a newer Pilot — this 3-pack simplifies your stock. The Non-OEM 15400-PLM-A02 is an aftermarket replacement that fits Accord, Accord Hybrid, CR-V, Civic, Odyssey, Pilot, CR-Z, and more from 1983 to 2022. That means one part number covers your whole fleet. One buyer confirmed: “I can use on my 2009 accord along with my 2019 Pilot which makes it very convenient!”
The dimensions of the box are 5.31 x 2.8 x 8.31 inches, compared to the ECOGARD filter box dimensions of 3.7 x 3.1 x 2.7 inches, which makes sense for three filters. The cans themselves are steel and plastic housings with a cellulose/synthetic fiber media blend. It is not quite the same filtration density as the Bosch FILTECH media, but for standard oil change intervals on daily drivers, the advanced filtration technology does the job. The manufacturer backs it with a 1-year warranty and strict quality inspections at each production stage.
You should know this is explicitly labeled as an aftermarket replacement, not original Honda/OEM. The housing uses cellulose/synthetic media rather than full synthetic, which is a step down in particle-capture efficiency. But reviewers report it “looks and feels oe” and “doesn’t appear to leak,” with many noting the value price for three filters. At 0.72 kilograms (about 1.6 pounds) total, it is heavier than a single premium filter, but you are getting three units.
What Works
- Three filters in one package — great for multi-Honda households
- Compatible with models from 1983 to 2022, including Accord, CR-V, Pilot
- 1-year warranty with quality inspections at every production stage
What to Note
- Cellulose/synthetic blend media is less efficient than full synthetic media
- No anti-drain back valve material specified — may be rubber, not silicone
Best suited for: anyone with two or more Honda vehicles who wants one box to serve all changes and does not need the highest-end filtration.
skip it if: you run extended 10,000-mile synthetic intervals and need a filter with higher dirt-holding capacity.
4. Genuine Oil Filter 15400-RTA-003 3-Pack with Drain Plug Gaskets
The exact Japan-made filter your Honda engineers spec’ed for the engine
For owners who trust nothing less than what came from the factory, this is the genuine 15400-RTA-003 — manufactured in Japan and sold in a 3-pack with three APSG drain plug gaskets (crush washers that seal the oil pan bolt) included. This filter is the current OEM replacement for the original part number, meaning it matches the thread pitch, bypass valve calibration, and gasket diameter that your 2008 Accord’s engine was designed around. There is no guesswork about fit or pressure rating.
At 4 x 4 x 4 inches per filter, it is compact. The total weight for three filters plus gaskets is 0.68 kilograms (about 1.5 pounds) — slightly lighter than the Non-OEM 3-pack but with the advantage of official Honda engineering. The filters come individually wrapped, so moisture does not affect the ones you are not using yet. The steel or aluminum housing resists deformation under the Accord’s oil pressure (typically 15-60 PSI depending on RPM). Buyers confirm “perfect fit for Accord 2014” and note “OEM quality with brand marking” and “no leaks.” The included crush washers save you a trip to the parts store during the change.
These filters are compatible with all Honda/Acura models that use the 15400-PLM-A01 or 15400-PLM-A02 filter — essentially every mainstream Honda from the mid-90s forward, with exceptions for S2000, Legend, and NSX. Since the Bosch single-pack is 3.0x fewer items (1 filter vs 3), this Genuine pack gives you a full year of changes for one car or a single change for three cars. The 1-year warranty from MAHLE TENNEX gives confidence, but at this tier, you are paying a premium for the OEM badge and the assurance that every internal spec matches the original engineering intent.
What You Get
- 3 genuine OEM Japan-made filters with exact Honda specifications
- 3 crush washers included — no extra trip to the auto store
- Individually wrapped, moisture-protected packaging
What Costs More
- Premium price tag compared to aftermarket alternatives
- Same media type as stock — no upgraded synthetic media for extended intervals
Choose this when: you want absolute fit certainty and OEM engineering, and you plan to keep the stock oil change schedule.
Consider an alternative if: you are on a tight budget or want a high-performance synthetic media filter for extended oil change intervals.
Understanding the Specs
Filtration Media
The material inside the filter that catches dirt. Cellulose (paper) is the basic standard — cheap but clogs faster. Synthetic blends (like Bosch’s FILTECH) trap smaller particles and hold more total dirt — up to 14 grams in the Bosch or 99% efficiency in the ECOGARD. For your 2008 Accord, a synthetic blend is worth it if you run extended intervals or drive in dusty conditions.
Anti-Drain Back Valve
A rubber or silicone flap inside the filter that stops oil from draining back into the pan when the engine is off. Silicone valves last longer and seal tighter. A good valve means your Accord gets pressurized oil instantly at startup instead of a dry rattle for the first second — especially important during cold weather when the oil is thick.

Final Thoughts: The Verdict
For most 2008 Accord owners, the 08 honda accord oil filter winner is the BOSCH 3323 because it combines the strongest dirt-holding capacity (14 grams) with a silicone anti-drain back valve and a price that lands in the middle of the pack. If you run synthetic oil and want a filter rated for 10,000-mile intervals, grab the ECOGARD S4610. And for the household with multiple Hondas who wants three filters ready to go, the Non-OEM 3-Pack delivers convenience at a reasonable cost.
