STILLEN 2009-2015 Nissan Maxima Hi-Flow Air Intake Kit [A35] - Dry Filter - 402962DF

Increase horsepower, throttle response, and induction sound with the STILLEN Hi-Flow Air Intake Kit for the 2009–2015 Nissan Maxima (A35). Designed and manufactured in-house at STILLEN’s U.S. headquarters, this intake system replaces the restrictive factory air box with a high-flow, free-breathing design that delivers real, noticeable performance gains — all while running perfectly on the stock ECU.

This intake features a polished aluminum intake tube paired with a custom-fitted polyurethane fresh air duct, ensuring cooler outside air is directed straight to the intake inlet. The result is improved airflow efficiency, quicker throttle response, and an aggressive induction sound under acceleration without unwanted drone during daily driving.

At the heart of the system is a high-quality STILLEN washable dry air filter, designed to provide excellent filtration with low restriction. Unlike oiled filters, this dry filter requires no re-oiling, making maintenance quick, clean, and hassle-free.

Dyno testing shows average gains of 8–10 wheel horsepower, along with improved torque delivery and potential gains in fuel efficiency during normal driving. Best of all, the STILLEN intake is a true plug-and-play upgrade — no tuning required and no check engine light.

Installation is straightforward and can be completed with basic hand tools, making it an ideal driveway install. Visually, the polished aluminum tube and molded duct dramatically clean up and enhance the engine bay, giving your Maxima a performance look to match its performance gains.
