has anyone ever swapped the ek9 intake cam ? is it just a direct swap? or do you need adjustable cam gears? or a tune?
Im not sure what your asking here. Swapping from what cam? In what engine?
I wouldnt bother. You wont see any noticable gain. Certainly wont need to tune for it.
oh ok thanks i was just asking because i know that the ek9 has a more aggressive intake cam
what does the 3 degrees of extra duration do exactly? does it make the vtec crossover louder?
