Infiniti G35 & G37 Body and Lighting Upgrade Guide: What Actually Fits

The G35 (2003–2008) and G37 (2008–2013) are two of the most modified Infiniti models on the road, and for good reason — they're affordable, rear-wheel-drive, and there's a massive aftermarket built around them. But before you start swapping body panels or lighting, it helps to know what's actually interchangeable and what to expect. Lighting is usually the first upgrade. Stock headlights on both generations get cloudy and dim over time, and today's aftermarket includes everything from basic OEM-spec replacements to full LED lighting kits, RGB headlights with app-controlled color, and halo headlights for a distinctive look at night. Tail lights follow a similar path — sequential and smoked options are popular for both coupe and sedan variants. If you're chasing a more aggressive front end, fog lights and a redesigned grille are usually done together, since fitment and mounting points are shared. Bumpers are where G35/G37 owners spend the most time researching fitment. Front bumpers, rear bumpers, bumper reinforcements, and bumper lips all differ between the 2003–2006 and 2007–2008 G35 facelifts, and again between G35 and G37 — always confirm your exact year before ordering. The reinforcement bar behind the bumper cover is steel on most trims and is worth inspecting if you're buying a car that's had prior bumper work. For bigger exterior projects, hoods (including vented and carbon fiber options), fenders, doors, trunks, and — for coupe owners — tailgates and hatch components are all available as direct-fit OEM take-offs or aftermarket panels. Side mirrors and mirror covers are a common quick upgrade, especially carbon fiber or painted-to-match covers. Less commonly discussed but just as important: roof panels, quarter panels, and rocker panels are the parts most affected by rust or prior collision repair, so if you're buying a used G35 or G37, it's worth having these inspected closely.
