Just wondering if you guys still do twin throttle body set ups for ecotec v6?? And a price if so??

Unfortunately, we stopped manufacturing those due to a lack of demand. Also, we have found that you can get approx 90% of the gains by using our 25mm manifold and 12mm plenum spacers as well as our 69mm throttle body and cold air intake for approx 20% of the cost when you take into consideration that the twin TB manifold required a custom tune to make it work.
