Using this MAF housing conversion kit is easy. First, make sure your vehicle is a 2016 - 2021 Honda Civic 1.5T or 2017 - 2022 Honda CR - V 1.5T. When you're buying an intake system from us, simply pick the MAF housing you want. You don't need to buy this kit separately. To install, start by carefully removing the old components and then attach the billet aluminum MAF housing, the 4 - ply silicone hose, and use the 304 stainless steel worm clamp to secure everything. As for maintenance, regularly check the connections to ensure they're tight. Also, keep an eye on the MAF housing for any signs of damage or dirt. If it gets dirty, you can gently clean it with a suitable cleaner. Note that this kit is designed specifically for the mentioned models, so don't try to use it on other vehicles.
