Cold Air Intake for Nissan Altima (2013-2016) 2.5L Engine

Maximize Throttle Response and Airflow for your Nissan Altima QR25DE

Who It’s For: Designed specifically for 2013–2016 Nissan Altima owners running the QR25DE engine who want to bridge the gap between a standard commuter and a more responsive, spirited drive.

The Problem: The factory intake on the QR25DE is engineered primarily for noise suppression. It uses restrictive, baffled plastic boxes and corrugated rubber accordion hoses that create massive air turbulence. This design causes the engine to work harder just to breathe, leading to sluggish throttle response and heat soak during summer idling.

The Solution: We replace that restrictive factory assembly with a mandrel-bent T304 aluminum intake pipe and a high-velocity air filter. By straightening the airflow path and utilizing a larger surface area for filtration, this system allows the QR25DE to pull in cooler, denser air with less effort, correcting the factory’s efficiency limitations.

Why This is the Ultimate Upgrade

• Performance Gains: By reducing intake restriction, this system can provide up to a 10% increase in horsepower and torque, particularly noticeable in the mid-to-high RPM range where the QR25DE usually feels breathless.
• T304 Aluminum Construction: Unlike the stock plastic that becomes brittle and cracks over time due to engine bay heat, our T304 lightweight aluminum piping is built to last the life of the vehicle while dissipating heat more effectively.
• Direct Bolt-On Fitment: This is a true "no-headache" install. It utilizes factory mounting points and is designed to work perfectly with your stock Mass Air Flow (MAF) sensor without throwing a Check Engine Light.
