There is a good read on it on the rawtek website. Helps reduce temps and also helps prevent sludge buildup. Additionally and the main reason I want it is that it comes with a boost tap directly off of it. I have a p3 multi gauge and it’s phenominal, however, when the Malone tune was written, the boost gets taken out of its slot. This means I am unable to read boost electronically. I have a tap but I have been too lazy to put the car on the lift, remove the pipe, and tap it and route it and then worry about a possible leak. Just takiing our the egr valve and asv and putting the pipe in place with the fitting would make it much easier. I was able to find the info I needed. Thank you!
