STILLEN 2016-2021 Nissan Maxima Hi-Flow Air Intake Kit [A36] - Dry Filter - 402967DF

Unleash improved throttle response, torque, and induction sound with the STILLEN Hi-Flow Air Intake Kit for the 2016–2021 Nissan Maxima (A36). Designed and manufactured in the USA, this intake system is engineered to replace restrictive factory components while retaining OEM drivability and reliability.

The STILLEN Hi-Flow Intake utilizes a polished aluminum intake tube paired with a custom-molded polyurethane fresh air duct, allowing the engine to draw in cooler, denser air for improved combustion efficiency. By optimizing airflow and reducing intake restriction, this system enhances horsepower, torque, and overall engine response without requiring ECU tuning.

A high-quality STILLEN washable dry air filter with increased surface area provides excellent filtration while maintaining low airflow resistance. Unlike oiled filters, this dry filter design requires no re-oiling, making maintenance clean, simple, and convenient.

This intake delivers an aggressive intake sound under acceleration while remaining smooth and refined during daily driving. It installs easily with basic hand tools and is fully compatible with the factory ECU — no check engine light and no tune needed.

Beyond performance, the polished aluminum tube and clean ducting noticeably enhance the appearance of the engine bay, giving your Maxima a performance-focused look to match its improved response.
