Your 2016+ Honda Civic 1.5T is packed with turbocharged potential, but the restrictive stock intake system is limiting its performance. The Mishimoto Performance Air Intake is engineered to increase airflow, improve throttle response, and enhance turbo spool, giving your Civic a noticeable boost in power and efficiency.

Designed for maximum cooling efficiency, the intake includes a fully enclosed, powder-coated steel airbox to shield the filter from engine heat, keeping intake air temperatures low for consistent performance in any driving condition. With a direct-fit design requiring no modifications or tuning, installation is quick and hassle-free. Whether you're looking for improved power delivery, a sportier turbo sound, or better overall efficiency, the Mishimoto Performance Air Intake delivers. Plus, with the Mishimoto Lifetime Warranty, you can upgrade with confidence. Give your Civic the airflow it deserves—upgrade today!
