Submited By: Piotr S. on 02/12/2011 i brought this piston head with "ICS Aluminum Piston for Extreme Upgrade" (from Evike.com :D)
the rubber piece seemed like 1mm smaller then form the one that i had, so i just swapped it, other then that looks realllllly nice just like other guy sad increases performance ... well its better that it wont brake with m150 spring for sure..
