I am selling a brand new, never installed Ultimate Racing Tial Blow off valve kit. I am looking to get $390.00 shipped for it. I am selling it because I bought it for my 135i. When I took everything apart today I noticed that the pipe that attaches to the throttle body in the 135i is way different from the one in the 335i. Thus, this kit will not work. I am looking to move this fast so it will go up on ebay on Monday. Feel free to email me with any questions. The kit is still in its original box and comes with all hardware and instructions. I have even mounted the blow off valve on the intake pipe for you already for a quick and easy install. Thanks.
