Description
The Mishimoto Performance Air Intake (MMAI-CTR-23) is a fully sealed, flow-bench-validated cold air intake engineered specifically for the K20C1-powered Honda Civic Type R and Acura Integra Type S. Flow-bench testing shows this air intake system reduces intake restriction by 17.9% compared to the restrictive factory airbox, and back-to-back dyno testing confirms 14.9 whp and 25.3 wtq gains over stock — with no tune required.
Unlike an open-element cold air intake exposed to underhood heat, the Mishimoto system uses a fully sealed, rotomolded airbox that isolates the included air filter from engine bay temperatures, preserving cooler, denser intake air for consistent power delivery run after run. Whether you’re cross-shopping this cold air intake system against an S&B cold air intake, a K&N cold air intake, an aFe cold air intake, or an Injen cold air intake, the sourced flow-bench and dyno numbers behind the MMAI-CTR-23 show exactly what a cold air intake system is designed to do: lower restriction and deliver more usable air to the turbo without sacrificing reliability or drop-in simplicity.
Vehicle Applications
This intake filter system is a direct-fit upgrade for the 2023–2026 Honda Civic Type R (chassis code FL5) and the 2024–2026 Acura Integra Type S (chassis code DE5), both equipped with the K20C1 turbocharged four-cylinder engine. Installation is completed with basic hand tools and requires no cutting, drilling, or fabrication on either platform.
