Our Picks at a Glance
How To Choose The Best 08 Infiniti G35 Coupe Parts
The 2008 G35 Coupe is a driver’s car, but after nearly two decades parts need replacing and upgrades make sense. Here is what to consider for each type of product.
Fitment is everything
A part that claims to fit an “Infiniti G35” may not work on the coupe. The coupe and sedan share some platforms but differ in body panels, exhaust routing, and interior trim. Always check the listing for “Coupe” wording, years 2007-2008, and verify your sub-model (like G35S or Journey).
Material quality vs. price
An engine splash shield made from rigid plastic can outlast a flimsy one by years. A car cover with six layers instead of three will block UV and hail much better. You get what you pay for when the material spec is spelled out.
Installation difficulty
Some parts, like a license plate bracket, take ten minutes. Others, like a short ram intake, may require modifying hoses or cutting tubing — read recent reviews before you commit. If you are not handy with tools, look for bolt-on items with verified “easy install” feedback.

In‑Depth Reviews
1. Sportuli Waterproof Car Cover for G35/G37 Coupe
Our pick — over 4★ from 200+ verified ratings; the strongest balance of quality and price.
Six layers of protection that turn your parked G35 coupe into a mobile garage.
This custom-fit cover from Sportuli is built specifically for the 2003-2015 Infiniti G35 and G37 Coupe — not the sedan. The outermost layer is high-density polyester with waterproof pressure rated up to 2000mm, meaning rain and snow bead up rather than soaking through. A reflective aluminum middle layer keeps the cabin cooler in direct sun, and the inner cotton backing protects your clear coat from micro-scratches.
Customers note it “effectively blocks pollen on black 370Z” and praise the zippered driver-side door for easy access without removing the whole cover. At 5 pounds, it is lighter than the DC Sports intake (7 pounds) and packs down into the included storage bag. The elastic hem and four wheel tie-downs keep it from blowing off in high winds — one reviewer drove from NJ to WA and noted the cover did not survive highway transport, though Sportuli does not bill it as a transport cover.
For garage-free owners or anyone storing their coupe for the season, this is a dense, well-designed barrier against sun, hail, dust, and bird droppings.
Strong points
- Door zipper for driver access without full removal
- Reflective stripes for nighttime visibility
- Mirror pockets accommodate folding and fixed mirrors
Know before you buy
- Not designed for highway-speed transport use
- Only fits coupe body style — not sedan or convertible
Perfect for: outdoor parking, seasonal storage, or apartment dwellers without a garage who want paint protection year-round.
Not your pick if: you need a cover to survive a cross-country tow or you drive the car daily and would be putting the cover on and off every day.
2. DC Sports SRI4205 Short Ram Intake System
The short ram intake that makes your 3.5L VQ engine breathe deeper and sound meaner.
The DC Sports SRI4205 replaces the restrictive factory airbox with lightweight aluminum tubing and a washable high-flow filter. It is 50-state C.A.R.B. compliant (EO# D-370-In), meaning it passes emissions inspections in California and other strict states. Buyers report it “looks awesome, sounds GREAT!!” and call it a much better value than a comparable K&N setup — one reviewer noted they “wouldn’t hesitate to buy again.”
The trade-off is fitment: at 7 pounds, the intake is noticeably heavier than the 5-pound car cover in this list, and several owners mention the crankcase breather nipples were welded in the wrong location, requiring cutting and adjusting. Unlike the splash shield below, which bolts right on, this one may take some mechanical expertise. The included DCf275 filter is reusable, so you save on replacements over time.
This is the only performance part on the list that genuinely changes how the car drives — sharper throttle response and a louder intake roar at full throttle.
What stands out
- 50-state CARB legal
- Washable and reusable high-flow filter
- Audible performance gain and sharper throttle
Real trade-offs
- May contact hood lining; minor modification needed
- Breather hose nipples reported in wrong position
- Mounting bracket can be tricky on right side
Grab it for: the driver who wants real intake sound and is comfortable with basic wrenching and slight modification.
Pass if: you want a pure bolt-on with zero cutting — look for a cold air intake with better-reported fitment.
3. CarPartsDepot Front Lower Engine Cover Splash Shield
The plastic shield that keeps road grit, water, and debris off your G35’s undercarriage.
This front lower engine cover replaces the factory splash shield that often cracks or gets torn off over speed bumps. It fits the 2007-2008 G35 Coupe as well as the G37, Q60, and QX50 — one verified buyer with a 2008 G37S Coupe wrote “Fits great, shipped flat.” The powder-coated black finish resists corrosion and looks clean when you peek underneath.
Unlike the DC Sports intake that weighs 7 pounds, this shield is made from rigid plastic that is surprisingly durable — owners mention it is “more rigid than I expected” and called it “perfect fit” on their 08 G37. It comes with a one-year warranty, so if it cracks prematurely you have coverage. Installation is straightforward: remove the old broken shield and bolt this one into the factory mounting points.
This is the sort of part you forget about until you hit a puddle at highway speed and nothing splashes onto your serpentine belt or alternator.
Why it works
- Direct OEM replacement number 75892JK000
- Powder-coated finish resists corrosion
- Verified fit on 2008 G35 and G37 coupes
One caveat
- Plastic can crack under extreme impact from a high curb
- No pre-drilled holes for aftermarket oil drain valves
Who needs this: anyone whose factory splash shield is missing, cracked, or hanging — this is a direct swap at a fair price.
skip it if: your car already has a fully intact shield, or if you regularly track the car and want an aluminum skid plate instead.
4. AUX Cable Harness for Infiniti G35 / G37 Sedan
The 3-foot harness that finally lets you stream music through your factory radio.
If you have a separate, compatible vehicle (such as a 2007-2008 Infiniti G35 Sedan), this harness plugs into the back of the factory stereo and gives you a standard 3.5mm AUX port. It is not designed for the G35 Coupe. It is designed for the 2007-2008 G35 Sedan and 2009-2010 G37 Sedan (part number 284H2-1BA0B). One reviewer confirmed it “works with 2008 Infiniti EX35 and iPhone 11 via 10-pin to Lightning adapter” — so you can use it with modern phones as long as the adapter supports data and music, not just charging.
A common workaround is pairing this harness with a Bluetooth adapter like the Bovee 1000. Reviewers point out it “enables iPhone music streaming” and “auto-connects for music, calls, and navigation audio through dashboard.” The harness only handles audio — it will not charge an Apple device and does not fit the iPhone 5’s Lightning connector directly. It is a lightweight install at just 2 ounces, about the same as a few loose coins.
This is the simplest way to bring your G35’s audio system into the modern era without replacing the head unit.
What works
- Restores music streaming through factory stereo
- Pairs with Bluetooth adapters for hands-free audio
- Lightweight and easy to route behind dash
Watch out for
- Does not charge any Apple product
- Won’t fit iPhone 5 or newer without adapter
- Some users report it does not connect to “iPod input” on certain radios
Reach for this if: you want to play music from your phone or a Bluetooth adapter through the stock stereo without ripping out the dash.
Look elsewhere if: you need a charging solution or have a non-Bose system — double-check radio compatibility before ordering.
5. Trunknets Rear License Plate Bracket for Infiniti G35/G37 Coupe
The bracket that replaces a crusty, faded factory plate holder in ten minutes.
This rear license plate bracket from Trunknets Inc fits the Infiniti G35 and G37 Coupe and Sedan from 2007 through 2015, plus the Q60 and Q40. One buyer with a 2011 G37S Coupe wrote “worked flawlessly” and noted the same bracket costs over from Z1 Motorsports. The bracket comes with two screws and two rivets, and the finish is powder-coated black to resist rust and fading.
Installation requires a rivet gun (not included) if you use the supplied rivets — buyers recommend buying a rivet gun from Amazon and finishing the job in under 10 minutes. Another reviewer said “it fit exactly as intended and was easy to install,” while one person noted the pins were tricky to secure but made it work. Unlike the DC Sports intake that weighs 7 pounds, this bracket is essentially weightless once installed.
If your factory bracket is cracked, faded, or missing, this is a direct swap that restores a clean look to the rear end without drilling new holes.
Why it is solid
- Direct fit for G35/G37 coupe and sedan 2007-2015
- Powder-coated finish prevents rust
- Includes hardware — screws and rivets
One hurdle
- Rivet gun required for rivet installation, not included
- Does not work with convertible models
Get this for: a cheap, clean fix when your factory bracket is ugly or missing — cheaper than the dealer by a wide margin.
pass on it if: you do not own a rivet gun and do not want to buy one — you can use the included screws but the fit may be less secure.
Understanding the Specs
Cold Air Intake vs. Short Ram
A short ram intake (like the DC Sports SRI4205) pulls hot air from inside the engine bay but is easier to install. A cold air intake routes the filter down into the fender for denser, cooler air — but risks hydro-locking in deep puddles. For a daily-driven G35 Coupe, a short ram is simpler and sounds great, but you may lose a few horsepower compared to a true cold air setup in summer heat.
Splash Shield Material
Most factory under-engine covers are made from pressed fiberboard or soft plastic that cracks after a few years. Aftermarket shields (like the CarPartsDepot unit) use rigid molded plastic that resists oil and water better. Aluminum skid plates offer the most protection but add weight and cost. For street driving, a quality plastic shield is the right balance.

Final Thoughts: The Verdict
For most owners of an 08 infiniti g35 coupe, the single best upgrade is the DC Sports SRI4205 Short Ram Intake because it transforms how the car sounds and responds while staying affordable. If you just want to keep your engine bay clean and protected, grab the CarPartsDepot Splash Shield.
