Description
The Mishimoto Performance Air Intake, part number MMAI-ACRD15-18, was engineered specifically for the 2018-2022 Honda Accord 1.5T to replace the factory intake tract with a precision rotational-molded airbox, a CNC-machined aluminum MAF housing, and a high-flow oiled filter. Together these components cut intake system restriction by more than 46-percent, giving Honda’s turbocharged 1.5L a more aggressive tone and measurable power gains without a tune.
This cold air intake pulls cooler outside air through an enlarged fresh-air inlet positioned between the grille and hood, insulating the filter from engine bay heat while a silicone coupler and CNC-machined MAF housing keep airflow smooth and air-fuel ratios accurate. The washable, oiled air intake filter is built from multi-layered cotton and protects the turbocharger and engine while supporting long-term performance. Drivers looking for a genuine performance air intake system that improves both sound and output on their Accord will find this setup delivers up to 7.8 horsepower and 7.2 lb-ft of torque to the wheels, installed as a direct-fit upgrade in under an hour with no other modifications required.
