I’m not a big fan of trucks, but my friend James did a good write-up on his Chevy Colorado cold-air intake install, so if your interested, here is a link.
If you’ve ever thought of dabbling with car modifications, a cold air intake is one of the easiest things to get started with. It won’t turn your Neon into a race car, but it’ll make a small difference, and combining it with a few other changes and a computer ugrade can create a lot of power.
