2016-2021 Honda Civic 1.5T (Non-Si) Cold Air Intake System Big Bore

The PRL Motorsports Cobra Cold Air Intake System for the 2016-2021 Honda Civic 1.5T (Non-Si) utilizes a 4-inch volume from the air filter into the MAF housing. It is available with two MAF housing choices: Standard Bore and Big Bore. Both use the factory MAF sensor but have different diameters. The Standard Bore housing provides factory-spec fuel trims without tuning, yielding gains of 15 horsepower and 12 ft/lb torque. The Big Bore housing, with a 50% larger air volume, requires a tune (Big Bore MAF basemap calibration on Hondata and/or KTuner) and delivers 20 horsepower and 15 ft/lb torque gains. This system reduces pumping loss and provides an unrestricted air path with ambient temperature air. Canadian models require a USDM windshield washer reservoir conversion (supplied by Teknotik). It is not compatible with the factory CVT cooler found in some international models (Spain, Turkey, etc.).
