Thanks for the response. I'm willing to try anything to get my Altezza up and running againNoyhing is really compatible. But if you can find a kit with the same maf sensor bolt in on a 3" pipe you can make your own with a 3" silicone 90 and a filter. I accually used the round peice from a stock airbox after i cut it out. It seems to work but i havent thouroly tested it yet. This is also alot cheaper than buying an apex or hks.
