2007-2012 Nissan Altima 2.5L Cold Air Intake Kit
The factory airbox on the 2007-2012 Nissan Altima 2.5L QR25DE chokes the engine with a baffled panel filter and a resonator maze before air ever reaches the throttle body, so the car feels muted off the line and the inline-4 sounds sealed shut. This Flashark cold air intake kit replaces the entire factory airbox assembly with a mandrel-bent aluminum intake tube and a high-flow dry cone filter behind a heat shield, so the QR25DE pulls cooler outside air with less restriction. On a stock Altima 2.5L, expected gains are approximately 3-7 WHP, with the real difference showing up as sharper throttle response from a stop and a more audible induction note under acceleration.
Installation is bolt-on with basic hand tools, the MAF sensor reuses the factory location and bore, and the dry filter never needs oiling, so it is a practical first upgrade for an Altima you already drive every day.

Key Features
- QR25DE-specific fitment: Engineered for the 2.5L inline-4 (QR25DE) in 2007-2012 Nissan Altima L32 sedans; will not fit the 3.5L VQ35DE V6 Altima because the airbox, MAF housing, and intake routing are completely different.
- Mandrel-bent aluminum intake tube: Black powder-coated 3.0-inch tube replaces the factory accordion pipe; smooth internal bends keep airflow velocity consistent and resist engine bay heat.
- High-flow dry cone filter: Oil-free synthetic media eliminates the risk of MAF sensor contamination from over-oiling; reusable with compressed air so there is no oil kit to buy or reapply.
- Heat shield included: Shields the cone filter from direct radiant engine heat so the intake pulls cooler air than an open-element setup with no shield.
- Approximately 3-7 WHP on a stock QR25DE: Realistic gains on an otherwise stock 2.5L; the bigger real-world change is sharper throttle response from a stop and smoother mid-range pull when merging or passing.
- Bolt-on install, no fabrication: Reuses the factory mounting points, all silicone couplers, stainless clamps, and hardware are in the box; no cutting, drilling, or permanent changes required.
- Audible induction sound under acceleration: Unlocks a deeper, more aggressive intake note above roughly 3,000 RPM without being intrusive at idle or highway cruise.
- 45-75 minute DIY install: Straightforward job with a 10mm and 12mm socket, a Phillips screwdriver, and a flathead screwdriver; suitable for first-time installers.
Who This Kit Is For
This Flashark cold air intake kit is for owners of a 2007-2012 Nissan Altima with the 2.5L QR25DE inline-4 who want sharper throttle response, a more audible induction note, and a reusable filter they never have to oil.
✓ For you if… you drive a 2007-2012 Altima 2.5L (S, base, or SR trim) as a daily and want a first bolt-on upgrade · you prefer a washable dry filter over disposable paper ones · you want the QR25DE to breathe audibly under acceleration · you have basic hand tools and about an hour to spare.
✗ Not for you if… your Altima has the 3.5L VQ35DE V6 (this kit is QR25DE-only) · you expect a guaranteed MPG gain (intakes primarily affect throttle response, not fuel economy) · you live in California or a CARB-adopting state and need an EO-numbered kit for street registration (see Compliance Notice below) · you plan deep-water crossings where the lower filter could ingest water.

Check Before Ordering
1. Confirm your engine. This kit fits 2007-2012 Nissan Altima models with the 2.5L QR25DE inline-4 only. Pop the hood and check the engine cover, or look at your VIN (4th character "C" = QR25DE 2.5L I4, "V" = VQ35DE 3.5L V6). If you have the 3.5L V6, this kit will not fit and may trigger a check engine light.
2. Sedan body style only (carried). Engine bay clearance and airbox mounting on the 2008-2013 Altima Coupe can differ from the Sedan even with the same QR25DE; if you have a Coupe, message us with a photo of your engine bay before ordering.
3. Intake style. This is a sealed cold-air intake with a heat shield that draws air from outside the engine bay, designed for cooler charge air and consistent power; not an open short-ram that pulls engine-bay heat.
4. Filter maintenance. Dry synthetic media, no oil required; clean every 15,000-20,000 miles by tapping out debris and blowing compressed air from the inside out, or rinse with water and let it air-dry fully.
5. CARB / emissions legality. This kit carries no CARB Executive Order (see Compliance Notice below); it is not legal for sale or use in California or other CARB-adopting states.
6. Install space and water. Bolt-on with hand tools, 45-75 minutes. The cone filter sits lower than the factory sealed airbox, so avoid standing water deep enough to submerge the lower bumper area; hydrolock can destroy the engine.
