bartkat Posted September 7, 2007 Share Posted September 7, 2007 It's just a resistor that makes the ECU think the intake air is cooler. It's not recommended. Quote Link to comment Share on other sites More sharing options...

ryukensfj Posted December 13, 2007 Share Posted December 13, 2007 Don't do it, if you are talking about the performance chips on ebay then don't do it. They can f**k up your car and you prob won't gain anything if it does. Quote Link to comment Share on other sites More sharing options...
