You dont need a spacer, and .022 seems to be the general consensus on the gap. You will need a thin wall spark plug socket, or take a grinder to yours. You have to make it fit inside the raised part on the rotor housings to seat the plugs all the way. Theyre shorter than the stock ones.
I had to switch to colder plugs in my GTU due to preignition problems. After 15-20 min of driving, my power would just go to ****, no matter how much I retarded my timing. I could never run 87 octane for the same reason. And my last set of brand new stock plugs lasted 5K miles before the electrode was gone. After I switched to the B8 and B9 EGV's, My car immmediately ran much better, and I havent looked back. 6K Miles, and I havent even needed to gap them of clean them once. And I can run 87 octane again, and my timign was put back to where it should be.
