Right the other day i was offered a P-flo kit for my S3 for pretty good money. So it would have been silly to turn it down, particularly as the all intakes give a fairly equal gain (yes debatable i know). Well i had a friend with me and we got to it. Although any silly fool can fit this intake, its easy! So if any of you are worried you'd make a hash of it, REALLY you cant. Firstly removing the factory intake system. Pretty easy. Just removed the constant tightening metal rings and riggled the top cover off and it came off with ease. Also taking the MAF out and putting it to oneside. A couple of screws need un-doing where the air original comes in through into the engine-bay. (little black ones) So with the plastic bits from the originals pushed aside. Simply push the rubber reducer on the turbo end and jubilee it on. Then put the main intake pipe into the other end of the rubber and once again jubilee. Fix on the smaller pipe, Push on, use the metal clip already on the original pipe. (3rd Picture) So then the main pipe goes across the back of the engine and down past the left hand side of the battery housing. There is a fixing screw to put on halfway down the pipe as it goes by the battery housing. So now, jubilee time again. fix the filter on. Moving back up the pipe, make sure you put the MAF sensor in, simply screw back in. Use screws supplied not the audi screws, the thread is different. There was a heat shield included. I didnt use it. I have heard chatter problems and metalic sounds happen. I tested it and really....tested it. It got warm but never stupidly warm. I could put my hand on it and grip it without getting burnt so heatsoak isnt too bad. However if in stop start traffic i can see it getting hot. Ill probably wrap it in silver foil tape to reflect the heat. The noise isn't excessively loud at all. Its just right. Just makes the engine sound more beefy. Rev's are much free'er flowing. Darth Vader does live in the glove box to some degree but its not loud loud. Just right. If i get enough people asking for the Darth Vader sound from inside the cabin ill shall do a video. If anyone needs help fitting this, Ill help. PM me. Here are some pictures of it fitted.
