Best Cams I ever had.

If you looking to build your motor, don't overlook these set of cams. Perfect fit and no modification needed. I love the engine noise and the engine power is very noticeable.

Fantastic Cams!!

Just installed a set of these cams on a 2005 STI. Havent gotten it to the dyno yet, but the car doesnt feel too bad driving across a parking lot. Added A LOT of sound which I know is a big concern to some people. Overall a great product!

  • Q: Estimated power  BooSTin 3 years ago


    How much power do you think I can make with a protune with just 475 wheel horsepower should I go for these or just keep stock cams

    • A: There would be gains over a stock cam at the high 400WHP range. The problem is there is no way for us to determine even the range of gains, as other variables such as tuning, fuel, head work, turbo size, ect are all playing effect on the engines power output.

  • Q: hp   bigwillwrx 3 years ago


    could i run these cams with less then 500 hp?

    • A: You certainly can but I doubt you would see as significant gains if these were being installed in a 500+ WHP vehicle. Thank you.

  • Q: valve springs and valves  Marco 4 years ago


    which valves and valve springs would you suggest for these cams?

    • A: These cams can be used with any direct replacement valves and valve springs as log as the springs are upgraded.
