Description
The Mishimoto MMAI-CIV-22RD is a direct-fit performance air intake system engineered specifically for the 2022+ Honda Civic Si, delivering a 50.7% reduction in restriction versus the factory air intake. Dyno-proven testing shows gains of up to 4.9 horsepower and 4.7 ft-lbs of torque, along with a more aggressive intake tone under acceleration. This isn’t a generic universal piece—it’s a purpose-built cold air intake designed to bolt in place of the restrictive stock system.
As a complete air intake system, this kit lets the engine draw in air more freely, which is the fundamental job of any cold air intake: reducing restriction so the engine can breathe and respond more sharply to throttle input. The injection-molded MAF housing is built from glass fiber-reinforced nylon for durability while integrating seamlessly with the factory MAF sensor and stock wiring. Rounding out the kit is the Mishimoto High-Flow Oiled Air Filter (part number MMAF-3005S), a multi-layered cotton intake filter designed to maximize airflow while maintaining strong filtration, paired with a red silicone coupler for a finished, factory-style look. Installation is described as simple and straightforward, making this an accessible air intake filter upgrade for owners who want a noticeable difference without a complicated install.
