Guest JAMIE T Posted October 19, 2005 Share Posted October 19, 2005 Hey, I'm just wondering if the large plenum intakes are much improvement on cars that are keeping the ITB's? What are the benefits? Quote Link to comment Share on other sites More sharing options...
AKWIKZ Posted October 19, 2005 Share Posted October 19, 2005 Actually I just got one. The size difference is substantial. They are a two piece design, with one side having nice air horn type runners. It also has a four inch inlet as opposed to the stock three inch. The main reason I got it was to cure the number 6 cylinder problem. They have a tendency to run lean on high boost because of the dog leg runner feeding number 6. The Greddy one is a full plenum all the way back feeding all the runners in the same fashion. It was not cheap, and it was a pain to get. Mine took almost four months from when I paid for it. I would suggest finding a place that can verify they have one in stock.

Guest JAMIE T Posted October 19, 2005 Share Posted October 19, 2005 hehe, I wasn't going to buy one, I was going to fabricate one like it. Greedy = too rich for me! The no. 6 runner is why I am considering doing it. Also, increasing plenum volume is good also. Quote Link to comment Share on other sites More sharing options...

What else did you say you needed Brian when you asked me at the Show? I totally forgot. Quote Link to comment Share on other sites More sharing options...
