mcsquish Posted April 22, 2007 Share Posted April 22, 2007 OK, what is the opinion on this? Does it actually do anything to help with the low pressure area back there? I've thought about putting one on, but it doesn't do anything, I would rather save up for a AP. Thanks for the thoughts. And yes I did a search on this, but not many posts. ________ Bmw M History Link to comment Share on other sites More sharing options...
