K&N Cold Air Intake Kit for 2013-2018 Nissan Altima 2.5L L4

K&N's state-of-the-art High-Flow Air Filter is engineered to shield your engine from contaminants, while a meticulously designed aerodynamic tube contributes to a guaranteed increase in horsepower and torque. Available in an assortment of finishes and powder coatings, K&N air intake systems are designed to improve acceleration, towing, and throttle response while providing world-class protection for your engine. Dyno-tested and providing more airflow compared to OEM intake systems, K&N intakes are easy to install and maintain, requiring air filter cleaning only every 100,000 miles.

K&N's cold air intake systems offer a less restrictive path for airflow, increasing the volume of cool, oxygen-rich air into your engine, resulting in an estimated increase of up to 8HP and up to 10 ft.lbs. of Torque. The intake systems allow your engine to breathe and sound as it should, with a distinctive growl on acceleration and a quiet return once at speed. K&N's horsepower/torque testing is performed on wheel-based dynamometers, and the reports are included with each intake system, ensuring trustworthy performance claims.

The signature, reusable K&N air filter combines 4 layers of pleated, breathable cotton with K&N's red filter oil to absorb dirt and dust particles, allowing clean air to continue flowing into your engine. A mandrel-bent and powder-coated aluminum intake tube helps increase the volume of airflow to your engine, while the heat shield protects the intake air from the high temperature of your engine bay, providing a more custom look under the hood.

K&N air intakes are designed for increased performance, outstanding durability, and sleek aesthetics. Backed by a No-Hassle Lifetime Limited Warranty, K&N air intake systems will not void the manufacturer's vehicle warranty. The entire air intake system can typically be installed in less than 60 minutes with basic hand tools, and K&N products are proudly made in the USA, ensuring trusted quality and reliability, supported by US-based customer support.
