dude if you haven't already, I recommend you get the headers asap, and at the same time change the plugs. Plugs on the factory manifolds seems impossible.
That's what I did, boy my car ran like a turd when you gave it some gas on the highway because ofthat. I tookit easy until I could swap in my headers (several long months).
