ACS splitter is the way to go, they have 2 one is called T5 and the other is T2 they range from 200-375.......As far as performance the throttle body spacer will do nothing...go with bbk longtubes ad a ported intake manifold...also a ported tb will be good to.....Hope this helps
Hi Richie! was looking for throttle body spacer for my 2010 camaro rs/1lt v6 that would not impact my engine cover. I heard if some are too big engine cover won't go on right....and was wondering your thoughts......also catch can that you do not have to empty and headers....just wanted to get an idea....Thxs!
