AEM Cold Air Intake System For Lexus 2013-2021 3.5L V6 F/I Gunmetal Gray Aluminum P/N 21-806C
Description

The AEM Cold Air Intake System (P/N 21-806C) is engineered to unlock horsepower and torque gains for select Lexus GS350 models from 2013 to 2021 with the 3.5L V6 F/I engine. By replacing the restrictive factory air intake system, this performance upgrade improves engine breathing and overall efficiency. At the core is an oversized, tapered cylinder-shaped AEM Dryflow air filter made from oil-free synthetic media, delivering excellent airflow and filtration. The filter is housed in the original air box location and protected by a heat shield that helps lower intake air temperatures for better power output. The intake tube is constructed from mandrel-bent aluminum with a durable gunmetal gray powder-coated finish, designed to reduce airflow restriction while adding an aggressive under-hood look. This intake system is engineered to work seamlessly with factory emissions control components, including the mass air flow (MAF) sensor and PCV hose. Itƒ??s easy to install using standard tools and is backed by AEMƒ??s Lifetime Limited Warranty. Legal status varies by region, so always verify local emissions compliance before purchase.

Key features:

  • Performance upgrade: Replaces restrictive OEM air filter and intake housing.

  • Dryflow filter: Oil-free, synthetic tapered filter delivers excellent airflow and filtration.

  • Heat shield included: Lowers intake temperatures to support better performance.

  • Durable construction: Mandrel-bent aluminum tubing with gunmetal gray powder-coated finish.

  • Emissions-ready: Compatible with factory MAF sensor and PCV hose.

  • Low maintenance: Filter usable for up to 100,000 miles before cleaning.

  • Simple installation: Designed for easy installation with standard tools.

  • Warranty: Covered by AEMƒ??s Lifetime Limited Warranty.
