fellas no need to argue

!! thanks for the opinions and the technical info. i think i will wait on them for now cause im buying so much other stuff. as far as spark plugs go, i heard the bosch+4's are no good with our cars, what should i go with. i have the magnecor 8.5 and the +4's and am experiencing bogging but i think thats from something else. i got a busted cat sensor which might be the problem, we'll see.
