What made you choose this particular product?
It's been a lot of debate a CAI don't do anything, but I lowered my intake temperatures 10 degrees over the OEM version. I have it routes to the front bumper.
Was it easy to install? Any installation tips that will help others?
It's made of 3 inch stainless tube, one foot long. Paint it with heat resistant paint to keep the heat radiation low.
