i just got my 8.5 CraneCams fire wire i ordered a few days ago and im going to switch the plugs with ac delco rapid fires. the reason why i am having trouble taking off my saprk plug wires is because they seem to be stuck or something, i can take the ends on the rotor/distributor off with ease but the actual plug hooked up to the spark plug wont budg at all, there is a metal thing coverign the plug that i can slide down i yank the plug hard "not like pu$$y hard but manly hard" but at the same time im worried i may damage something by pulling ot hard, should i just yank the **** out of it or is there a better way?

also so kill 2 birds with one stone, since my engine is bone stock at this time besides the modded air intake, will i actually fell an increase in acceleration by adding the crane cams & the rapid fires?? how much more of a pluse is it? and how long should they last me.

P.S. chekc out my new sig

If you dont care about the old wires, just take some pliers and pull. The terminals are probably stuck on the end of the spark plugs since ur car hasnt been been tuned up and a while and most likely rusted on or something of the sort.

The rubber boots tend to bond to the plugs if you don't use a tune up grease. Don't jerk the wires, you'll just end up hurting yourself. Grab them firmly at the boots (it helps if the cars been sitting overnight so its not hot) and twist them till they break loose. After that they should come right off.

To answer your second question, unless your current wires are bad or your current plugs are fouled or ancient, you probably won't see any noticable performance difference. I also wouldn't put a lot of faith into Rapid Fire plugs. I mean how good can they be if after how many years GM redesigned them? I've run stock AC plugs, Rapid Fires, and Bosch Platinums... anymore I'll use the Bosch plugs because they're CHEAP and they work.

have to agree AC rapid fires suck. I have heard many a bad word about them. I have autolight platinum and they work great.

 

I never re-installed those metal sheilds over the plug boots for that exact reason; I couldn't get the boots off. Use a ton (as in, overkill) of dielectric grease in the new plug boots. Use a q-tip to slime it in there. I also put some of the dielectric on the spark plug's ceramic insulator with my finger. You won't need the dielectric grease (aka "tune up grease") at the distributor cap.

Make sure you hear the faint "click" of the new plug wire as you attach it to the spark plug... that way you know the plug wire's connected.

Also, what I do for every car I work on, is draw a diagram of the plug wires as they go from their positions on the cap to their positions on the engine. That way I have a back-up diagram in case I goof up the firing order. Rememeber, on our 2.8's, the #1 cylinder is the frontmost PASSENGER cylinder. Just about every other engine out there uses the frontmost driver's side as #1; not ours.

thansk for the responses guys

sweet got it tomP , if you could be so kind as to make a diagram of the way the plugs are supposed to be in order "i mean hooked on the distributor that would be awesome. i am car blonde at this time so anyhtign would be helpful lol

 

Well, I would, but every car's gonna be different. People think that the location of the #1 plug wire on the distributor cap must be in a certain location relative to the engine- but in reality, it can be anywhere. For a long-winded explanation of this, with a few lame text-pictures, check out my old message at: https://www.thirdgen.org/messgboard/...ML/000866.html

I'll e-mail you a quickly, badly-windows-paintbrush'd example of what a spark plug wire layout diagram looks like, though.

I had the same prob. Sence i was replacing the wires I just pulled the dam wire out of the boot. Then used a pair of neddle nose pliers and pulled the boot off. Then I was able to grab the litle metal clamp and pull it off with no prob.

Proboly not the best way, but I got pissed off.
