Like most others, I didn’t like the Jackson racing turbo air filter location. For the most part, the turbo kit is a good system, except for the air intake location in front of the rear tire. I bought a Donaldson filter housing with 4” inlet and 3.5” outlet. This is 1/2” bigger than the Jackson filter. This should allow for more flow in the future. Plus the filters are $36 and easier to change. Here‘s some pics of the filter and piping. I am getting a 135deg. Elbow for the intake side of the filter for the dunes, and use the Donaldson top spin pre filter for the dirt. It’s a bit bigger than I wanted, but want to protect the turbo
