Best advice I can give u for the Stillen kit is to go with the Air 2 Air kit upgrade
Topgunz - air to air upgrade
Stillen kit has a lot of cooling issues with its Air to Water set up...The A2A kit solves that and other issues like getting true "intake temps" which are post blower with the A2A design. It als9 gives you room to grow and upgrade on the power band side.
