It's mostly custom especially the chrome heat shields. I cleared the inside of the engine cover (with Dremel) after removing the square filters for more air under the cover.

Cut some tubes and add the K&N cone filters. I have to make the front air inlet bigger to be able to fit a bigger RAM tubing or you can keep the inlet and cut the stock plastic tube to feed the tip of the cone filters with cold air.

It's very simple and doable to newbies like me.
