My AFM power pipe was the worst thing I've ever bought for my car. Read the stangnet reviews about it. Here's my complaints;
-No oil breather line, had to fabricate a filter for the hose that now just sits on top of the valve cover.
-Horrible fit. You'll have to play with it for awhile and twist it everywich way to get it to fit right.
-The pipe hits the alternator and oil cap, and now the ceramic coating is rubbing off on those two spots.
-The pipe is made to rest in the hole in the fenderwell, there is no attachment to hook it into the side of the fenderwell. I had to line the whole fenderwell with rubber so the ceramic coating wouldn't rub off.
The way the pipe is built you have to fabricate your own way of keeping it in the fenderwell otherwise it will bounce around all over the place since the only thing keeping it in place is the rubber sleeve to the throttle body. AFM even admits this and told me the pipe is really only designed for strip cars.
Also the pipe puts the air filter right down at teh bottom of the fenderwell so don't drive through any puddles with it or you'll lock up the engine.
I also didn't feel any power difference with it, $229 down the drain.
If I had to do it all over again, I would make my own CAI like Vib and some of the other guys in here. If you have any other questions about it PM me.
