Cold Air Intake for 2013-2018 Nissan Altima SV S SL SR 2.5L 4 Cylinder
Give your 2013-2018 Nissan Altima's 2.5L 4-cylinder (QR25DE) engine the airflow it was never given from the factory. The Flashark Cold Air Intake Kit replaces the restrictive factory airbox and plastic intake tract with a smooth, large-bore aluminum intake system that pulls cooler, denser air from outside the engine bay — delivering noticeably sharper throttle response, stronger mid-range pull, and that satisfying turbo induction note every time you step on it.
Built with mandrel-bent aluminum piping and a high-flow cone filter, this kit comes complete with all hardware for a true bolt-on installation. No cutting, no welding, no fabrication — just basic hand tools and about 60-90 minutes of your time.
Compatible with 2013-2018 Nissan Altima SV, S, SL, and SR trim levels equipped with the 2.5L QR25DE 4-cylinder engine.
Brand: Flashark
Type: Cold Air Intake
Include 1X Performance Cold Air Intake

Why Upgrade Your Intake?
The factory intake on the 2013-2018 Altima 2.5L was engineered for one thing: cost minimization. The molded plastic airbox, small-diameter tubing, and dense paper-element filter are all designed to be cheap to manufacture — not to help your 2.5L make power.
On a daily-driven sedan, the gains from a cold air intake are immediate and real:
- Faster throttle response — your foot matches the engine's will from the first press; no lag, no hesitation
- Stronger mid-range torque — the 2.5L pulls harder in the 2,500–5,000 RPM range where most daily driving happens
- Better fuel efficiency — more complete combustion under light load means fewer fuel trims
- Real airflow sound — the factory system completely mutes the engine; the Flashark intake reveals the QR25DE's induction note under load
- One filter, life of the car — never buy another $25 OEM paper filter again
Whether you're commuting, carpooling, or just enjoying the drive, a cold air intake is the best first upgrade for any naturally aspirated 4-cylinder engine.
