well I found the AFE on ebay for 60 dollars he had it on his car for 1000 miles then got the RBC manifold. I noticed on the description on the p2r and the afe where different on how they make power.
P2R- creating a larger volume of air in the intake manifold and optimizing the air path to the cylinders.
aFe- a serrated/helix design that creates turbulence in the air flow at the point just prior entry into the engine optimizing the combustion cycle.
Anyways was just wondering what people thought between the two. I guess I will see soon enough wasn't going to guy one but for 60 dollars free shipping why not right?
I went with the aFe spacer and it does help some. I feel there is more to the design with the aFe but who knows you can not tell unless we see before and after on a dyno from both.
