The gasket-matching has been said to be worth a few HP on ICEolator installs with stock intake manifolds. The ported IM + ICEolator has been said to have a combined gain in the range of 30HP.
Sorry I am still a little... confused....
Can I purchase a ported IM online for my 1LT? If yes, where?
If I choose not too... will the ice-olator add all the stats it says on the site?
