If I was you I would seriously consider go the extra $$ and get a Breathe intake instead. I am probably going to get one to replace my Polaris, remove the internal air box baffle and retune. I am just trying to work out the best course for retuning. I will probably also get the TPUSA 813 cams while I'm at it. But that means finding a set of used cams to swap with.
Cheers, Richard
