Velocity Stacks?
 

I want to know your opinions on the velocity stacks on 1krr's.


Short? Long? None? And why. I know the 04-05 guys switch to 06, but i dont know what the exact difference is between the two.

Is there a certain length for top-end or low end? And why have different lengths on outboard/inboard cylinders?

RE: Velocity Stacks?
 

I just installed '06 stacks in my '05. The bottom is the same as well as the giht but the top is wider. I only got them becuase I stripped the screws and they came with screws (on ebay), so the stacks were free basically. To take advantage of the difference you will need a remaped PCIII. I also have an elarged intake.
