lol I cant say for 100% sure but a friend of mine told me someone he knew drilled a hole though the manifold... but don't get your hopes up lol just, deal with the opti for a while and get used to it its no that hard once you've done it 3-4 time with in a year lol or you could just buy an msd cap and rotor, they have an extra bolt that keeps it tighter or you could go with coil pack conversion still uses opti but just for the sensor inside...
