so i want to buy headers but i'm not paying a shop to put it on, my friend and i will d the work, but I want to do a tune up as well but i am having trouble getting to the back spark plugs and i'm concerned about the plug boots and the casing around them. Are the casing and/or the boots connected to something? cuz i tried to take off the boot but it was on there pretty good and i didnt wanna chance ripping the wires out of the boot (i have done that before) so do i just need to use more force or do i have to disconect something? and how do i get to the plugs in back? thanks
oh and one more thing, my car is ETC, is there anyway to rev it from the engine bay?
