AEM HCA Cold Air Intake System For Lexus IS250 / IS350 2013ƒ??2021, 3.5L V6 ƒ?? Gunmetal Gray P/N 22-688C

The AEM 22-688C HCA (High Capacity Airflow) Cold Air Intake System is engineered to improve horsepower and throttle response for Lexus IS250, IS350, and RC350 models from 2013 to 2021 equipped with the 3.5L V6 engine.

The included AEM DryFlow synthetic air filter offers high flow and excellent filtration while being washable, reusable, and oil-freeƒ??lasting up to 100,000 miles before cleaning is needed under normal driving conditions. Installation is simple and can be completed with basic hand tools. Backed by AEMƒ??s Lifetime Limited Warranty.

  • Designed for Performance: Replaces restrictive OEM intake tubing to increase airflow and horsepower.

  • Application-Specific Fit: Compatible with Lexus IS250 / IS350 / RC350 (2013ƒ??2021) with 3.5L V6 engine.

  • Factory Airbox Integration: Retains OEM airbox for ease of installation and OEM-style fitment.
