Description
The Mishimoto Performance Intake Kit, part number MMAI-CTR-17, was engineered specifically for the 2017-2021 Honda Civic Type R (chassis code FK8) and its K20C1 turbocharged engine. Rather than reinventing the wheel, Mishimoto’s engineers built on the factory aluminum runner from turbo to induction boot, then re-engineered everything downstream — the intake hose, MAF housing, and airbox — into a single, freer-flowing air intake system that unlocks measurable gains without a tune.
This cold air intake replaces the restrictive, accordion-styled factory hose with a 5-layer silicone elbow embedded with heat-resistant fibers and reinforced with steel wire, so it holds its shape under boost while smoothing internal airflow. Paired with a precision-adjusted CNC aluminum MAF housing and a redesigned, powder-coated black airbox that houses the Mishimoto high-flow oiled air filter, the complete air intake filter and hose combination is 42-percent less restrictive than the stock airbox, filter, and elbow. The result is a max gain of 16.7 whp and 20.1 wtq while maintaining safe air/fuel ratios and running check-engine-light-free on the stock tune — everything a Civic Type R owner wants from a cold air intake filter upgrade without chasing a custom calibration.
Vehicle Applications
This intake kit is a direct fit for the 2017-2021 Honda Civic Type R, chassis code FK8, equipped with the K20C1 engine, and it also fits the 2021 Honda Civic Type R Limited Edition. The airbox retains the factory rubber snorkel and the dedicated intake channel built into the CTR’s hood, keeping the cool air intake path intact while improving flow.
