Mishimoto Red Performance Air Intake - Honda Civic Si, Acura Integra 2022-2026

The Mishimoto Performance Air Intake is a direct-fit upgrade for the turbocharged 1.5L Honda Civic and Acura Integra that cuts intake restriction by 50.7 percent versus the factory system, letting the engine draw air more freely and sharpen throttle response. An injection-molded MAF housing in glass fiber reinforced nylon holds its shape under heat while matching the stock sensor placement, and the included Mishimoto high-flow oiled air filter maximizes filtration without choking airflow. Dyno testing confirms gains of up to 4.9 whp and 4.7 wtq along with a more aggressive intake tone under acceleration. The kit installs with basic hand tools and requires no tune.
