Best air filter kit

[aalsalem]

Hi, got a 2009 softail 107ci with stage 4 hillside cycles heads, woods cams, 58 tb and all the goodies and looking for what's the best preforming air filter kit ? Anyone got any ideas ? Don't really care how it looks, just looking to get the best numbers out of my bike.
Thanks for any help

Quick and easy is the S&S Stealth with the 1" taller filter.  You can use your own cover or pick one of their many styles.

Added later:

I should mention that with the 1" taller Stealth, removing the breather on the dyno showed no improvement.  That means it was easily supporting a 148 hp / 145 tq 120" engine.

Currently have a zippers performance MaxFlow Replacement Element on it, is the S&S better than the zippers ?

I would ask Hillside. Or you tuner.

Stealth or HPI.

I'll throw in my $.02 worth. R & R Cycles, comes with external breathers and the taller filter.     Coff 06
