Description
The Mishimoto Performance Air Intake (MMAI-ACRD20-18) is purpose-built for the 2018-2022 Honda Accord 2.0T, targeting the detuned K20C4 turbocharged four-cylinder that took the place of the Accord’s outgoing V6. This isn’t just another generic cold air intake filter swap — it’s a complete air intake system anchored by a precision-adjusted, CNC-machined aluminum MAF housing paired with a silicone coupler, engineered to unlock flow that Honda’s factory intake leaves on the table.
Where some cold air intakes promise big numbers without backing them up, this Mishimoto air intake delivers measurable results: a 50-percent increase in flow over the stock system, with max power gains of 15.6 whp and 12.9 wtq while maintaining safe air-fuel ratios and requiring no tune. A Mishimoto high-flow oiled air filter pulls maximum airflow from the front of the vehicle and sits inside a robust rotational-molded airbox that blocks underhood heat soak for a genuinely cool air intake experience, while a carbon-fiber lid tops off the engine bay with a cleaner look. Whether you’ve been comparing an S&B cold air intake, K&N cold air intake, aFe cold air intake, or Injen cold air intake for this platform, this kit stands apart with its dedicated intake filter tuning, tune-free calibration, and the Mishimoto Lifetime Warranty for worry-free installation.
