Using this conversion kit is straightforward. First, make sure your Honda Civic is from 2016 - 2021 and has a 1.5T engine. If you have a Canadian model, you'll need to get a USDM windshield washer reservoir conversion kit separately. And note that if your car has a factory CVT cooler, especially in Spain or Turkey, this kit won't work for you. The air filter isn't included, so you'll have to buy one. To install, use the parts in the kit to turn your PRL Motorsports Short Ram Intake System into a Cobra Cold Air Intake. You'll find an HDPE rotomolded lower intake tube, a 4 - ply silicone hose, two CAI brackets, two 304 stainless steel worm gear clamps, and a hardware bag with a billet clutch line relocation bracket. For maintenance, regularly check the connections of the tubes and hoses to make sure they're secure. If any parts look worn out, replace them promptly.
