I was looking for a set of these to replace the ones in my car/have a new set on hand and I e mailed AC delco and they told me this.

"We appreciate your inquiry regarding the Rapidfire spark plug.
We searched our system and found the following information. The old can be
identified by a copper star or ridged center electrode. The NEW platinum
style will have a tiny platinum pad on the center electrode. However, most
of the old style should be gone by now."


here is the part gm # for them that I gave them.
25164643

I emailed them back asking if they can locate some of the old ones for me. If not I will have to run a different spark plug. Damn it, these worked out great.

I will post back with any updates I get from AC delco.

cool. keep us updated.

well i work at autozone and we stock them regularly, so y is it hard for u to get them?



DRIVE HARD OR DONT DRIVE AT ALL!!!

platinum or non platinum?

you got a autozone part #?

non platinum. if u just go in there and tell them u need ac delco rapidfire #5's then they should come out with the non platinum ones. unless ur talkin about the platinum ones. at least i think there non platinum.

that part # i asked about and those refer to #12's from what the guy told me

i went into the ac delco store and they have the #5's but the part # on the box is 25164643, are these the right plugs?

Are they really?That sucks.I gotta go over there tommorow and have them reorder the right ones.25164643 are the right ones,but according to jake they are the old ones.I dont know if they changed the part number for them.Ill try to find out tommorow if the part number changed when i return the plugs i ordered.Thanks for telling me.

so damn confusing.

keep us updated peter.

thanks

Look at the box.

If it has the Gold boarders, its Platinum.
If it has the Silver boarders, its NON-Platinum.

I have a couple boxes of the Platinum ones, I can post a pic of. They dont have the part number on them, just a UPC and the #5.

im a dumbass, if i would have reread jakes first post i would have answered my own question. im gonna go buy my plugs

i am talking to killerquad(jake) and he works at a chevy parts counter.

he is currently running a ac delco plug that is 2 steps colder . We all know he is running gobs of nitrous with great results. He has some chart with the part #'s and heat ranges , but they were at his house.

so when i get that # i will post it.

but the #5's will work just fine and what do we gap them to?

well i guess autozone sells the platinum ones by what speedracerz says. cause the ones i have are the ones with a gold border. srry to misinform u all


DRIVE HARD OR DONT DRIVE AT ALL!!!

what do we gap them to?

without an upgraded ignition system i gap mine at .40 and seam to have no problems.with the ignition.
