Hi All, I was considering the IPD Plenum as well, did some research here and They have mixed reviews, The test results show No gain at all. others say they feel it ect. ect. I was an engine builder in my past life and can say that on a turbo car, Its hard to imagine that the staock plenum under several atmospheres does not flow as it should. The ECU tune is by far the best bang for your buck. I am looking for 50 more HP now... Thoughts ?

 

I have the vivid carbon pipe and tho it was tuff to get the sleeves over the piping it fit. I sprayed some grease on the couplers to help them slide on
