pureboiracer 0 Report post Posted June 21, 2007 sooo. i got some parts a few days ago for my conversion from pfl to facelift for me e30 325i. looked at the throttle body and got lost. ok so iv worked out there are 2 pipes conected to air filter pipe for the brake booster. 2 for the coolant hoses and one next to them for the breather pipe. now.... there is another fitting after the butterfly and one in the air filter pipe that goes into a black canister type thing with a plug in the bottom for the loom. does anyone know where these 2 pipes go?
