Just browsing as you do at various parts...
Short question really, when combined with other bolt ons (exhaust, high flow cats, filter etc) and a remap, are the much gains to be had from either the Kinetix Manifolds?
On the flip side what are the options on a Revup?
I here that a Plenum Spacer provides no gains, though have heard some talk of using a spacer with a pre-revup upper plenum?
Sounds a lot cheaper than either of the above options anyway.
