| Position | Front |
|---|---|
| Quantity | 2 Piece |
This TRQ two-piece front inner fender liner set replaces the forward driver and passenger side liners for select Infiniti G35 (2007-2008) and G37 (2009) sedans. It is sold as a pair and intended as a direct replacement for worn or damaged factory liners to protect the wheel wells and engine bay from road debris and water.

|---|---|
| Vehicle Service Type | Car |
| Fit Type | Vehicle Specific Fit |
| OEM Part Number | 63845AM800 |
This front left splash shield from Crash Parts Plus is a direct replacement fender liner intended for the 2003–2007 Infiniti G35. It mounts in the front wheel well to protect the engine bay and inner fender from road debris, water, and salt. The liner is offered as a vehicle-specific fit which simplifies installation for DIYers and service shops, and several buyers report an easy, straightforward fit on G35 coupes and sedans.

| Fitment | 2003–2007 Infiniti G35 Coupe Front |
|---|---|
| Position | Front, driver and passenger |
| Material | Plastic |
| Compatible part numbers | 63842AM800, 63843AM800, 63844AM800, 63845AM800 |

4. Garage-Pro Fender Liner Front Left for Infiniti G35 (2003–2007) Coupe
| Fit Type | Vehicle Specific Fit |
|---|---|
| Auto Part Position | Front |
| Vehicle Service Type | Car |
| Material | Plastic |
This Garage-Pro fender liner is an aftermarket, direct-fit replacement for the front left section of 2003–2007 Infiniti G35 coupes.

- Low-cost alternative to factory replacement, sold individually so you can replace only one side
- Lightweight plastic resists moisture and road grime for basic protection
- Requires only common hand tools for installation
- Fit can be imperfect compared with factory parts and may need trimming or adjustment
- Plastic material is lower grade than some OEM liners and may wear faster over time

|---|---|
| Installation Type | Screw-In |
| Finish Type | Powder Coated |
| Automotive Fit Type | Vehicle Specific Fit |
| OEM Part Number | 63840EA800 |
This Parts N Go front right fender liner is an aftermarket replacement intended to match the shape and mounting points of the original part it replaces. It is sold as a passenger-side splash guard that installs with screws into the wheelwell and is finished with a powder coat for corrosion resistance. In typical use it protects the inner fender and engine bay from road debris, water, and mud and restores the covered area after damage or deterioration of the original liner. Reviewers report generally good fit and finish when the liner is aligned carefully, though some customers needed patience, a bit of force, or heat to flex plastic around tight spots during installation.

Choosing the Right Infiniti G35 Fender Liner: Key Factors to Consider
Material Durability
The material of the liner determines how well it resists cracking, abrasion, and seasonal temperature swings. Durable plastics or molded composites resist stone chips and repeated flexing from road impacts.
Inferior materials can become brittle and split, leaving the wheel well exposed and increasing the chance of corrosion or damage to wiring and suspension components. Consider liners that specify impact resistance or thicker molding in high-wear zones.
Fitment Accuracy
Accurate fitment ensures the liner aligns with factory mounting points and follows the contour of the wheel opening. Good fit reduces gaps where water and debris can enter and prevents flapping that causes noise.
Poorly fitting liners often need trimming or extra fasteners, which increases install time and can compromise protection. Prioritize parts that are described as vehicle-specific or matched to the G35’s body shape for the cleanest installation.
Mounting and Fastening Compatibility
Check what types of clips, screws, or bolts the liner is designed to use and whether those match the Infiniti G35’s existing hardware. Kits that include compatible fasteners make installation easier and more secure.
If the liner requires different fasteners, factor in the time and effort to source and fit those parts. Secure mounting prevents movement that can abrade nearby paint or create noise while driving.
Coverage and Splash Protection
A liner’s shape and coverage determine how effectively it deflects water, mud, and stones away from suspension parts, brake lines, and inner body panels. Wider coverage with strategic flanges helps keep contaminants out of hard-to-reach areas.
Less coverage may expose edges of the fender or inner panels, increasing the risk of rust. Evaluate how the liner channels fluid and whether it incorporates raised edges or baffles for better splash control.
Ease of Installation
Installation complexity affects whether you can replace the liner at home or need professional help. Easier installs use existing mounting points, require only common hand tools, and include clear instructions.
Complex replacements that demand wheel removal, trimming, or special fasteners add time and potential for error. Consider your mechanical comfort and whether the kit includes hardware and guidance to streamline the job.
Maintenance and Repairability
Over time, liners can detach or suffer localized damage. Choose liners that are easy to inspect, clean, and service without removing large assemblies. Removable sections or accessible fasteners simplify periodic checks.
Repairable liners let you replace just the damaged portion rather than the whole part. This reduces downtime and can be more economical if you need to address minor tears or scuffs later on.
FAQ
How do I know if my Infiniti G35 fender liner needs replacing?
Look for visible cracks, large holes, missing mounting clips, or excessive movement when you push on the liner. Water pooling in the wheel well, rubbing noises while driving, or exposed wiring and suspension components are also common signs that the liner is no longer providing adequate protection.
Can I install a fender liner myself or do I need a mechanic?
Many fender liners can be installed at home with basic tools, especially if they reuse the vehicle’s original fasteners and mounting points. However, if the job requires wheel removal, trimming of the liner, or replacement of specialty clips, you may prefer professional help to ensure proper fit and secure attachment.
Will replacing the liner prevent rust on my Infiniti G35?
A properly fitted liner reduces the amount of water, salt, and debris that reach inner panels and suspension areas, which lowers the risk of rust. It does not reverse existing corrosion, so inspect and address any current rust before or during liner replacement to improve long-term results.
What should I do about missing or broken mounting clips?
Replace broken clips with ones that match the original fastener style and size to maintain secure attachment. Many kits include compatible hardware, or you can source OEM-style clips that fit the Infiniti G35’s mounting points for a reliable repair.
Are plastic liners durable enough for daily driving and winter conditions?
Modern plastic liners manufactured from impact-resistant polymers typically hold up well under regular driving and seasonal temperature changes. Longevity depends on material quality and thickness, so choose liners specified for resistance to cracking and abrasion if you frequently encounter harsh road conditions.
Does installation affect access to brakes or suspension during maintenance?
A correctly installed liner should not obstruct routine brake or suspension work, but some installations may require partial removal to access certain components. Look for liners that allow easy removal of a few fasteners to simplify future maintenance tasks.
How We Chose the Best Infiniti G35 Fender Liner
We focused on criteria that matter specifically for Infiniti G35 fender liners. Primary filters included material durability, measured resistance to cracking and abrasion; dimensional accuracy, meaning how closely the part matches factory contours and mounting points; fastening compatibility, ensuring the liner works with common clip and bolt types used on the vehicle; splash and coverage design, to assess how well the liner directs water and road debris away from critical components; and installation complexity, covering whether the part can be installed with basic tools and modest experience. We excluded parts that required bodywork modifications or extensive trimming beyond minor edge adjustments. We also set aside liners with uncertain material specifications or poor customer feedback on fit. The final shortlist balances longevity, practical protection, and straightforward installability for the Infiniti G35.
Our full evaluation process is outlined in our review methodology.
Conclusion
When choosing an Infiniti G35 fender liner, prioritize material durability and precise fitment to ensure effective protection and quieter operation. Balance coverage and mounting compatibility with how comfortable you are performing the install. Accepting minor tradeoffs between thinness and flexibility is common; thicker molded liners often last longer but may require slightly more effort to fit. Focus on secure attachment, adequate splash protection, and ease of service to get the best long-term value.
