Rapidfire vs. Platinum?

I had to make a decision between buying Rapid-fire or Platinum Spark Plugs (both from AC Delco) for my 96 Jimmy. I went ahead and bought the OEM part, the regular AC Delco Platinum, thinking I couldn't go wrong with that...but, does anyone know what the difference between these two spark plugs is???

I was told by the autopart guy that the rapid-fire were a "hot" spark plug. He couldn't explain it better, or I guess I didn't understand him. Can anyone?

Rapid fires are good for our trucks as oem replacements.... They allow a hotter spark as well (good if you run an MSD 6x or what have you...) Though I run platinums right now with no noticeable decrease in performance from my MSD.

What model number of platinums are you using in a 1995?

It doesn't list them as an option for that year? I might try them out.

Let me know.

Perfect, remember to use a gap of 0.060.

the part number for delco plats for 1995 is 41-803. I was told the 41-932's wouldnt work. Go figure.

I am going to do a tune up on my g/f 95 jimmy, and was looking around for cheap delco plat plugs. I tried all over and they all tell me the delco 41-803 plats are the ones I should get. 8 bux a plug. The retards at autozone even tried to sell me some autolite crap wires and shit, I was like, um, hell no, only ac delco for gm vehicles. But anyways, ok, I'll prove it to you I know what I'm talking about. go here http://www.acdelco.com/html/catalog/index.htm and enter 41-803

oh, yeah, and if you get your plugs changed over to delco plats, post here, and let us (me) know if there is any better performance or any better gas milage. What plugs and wires are you using right now?

No offense intended, but there is no Vin W 1995 4.3L Blazers under 41-803 .

I also go to http://www.acdelco.com/html/catalog/index.htm, to check out the actual part numbers for my truck. By the way, I am currently using Taylor Spiro Pro Custom Spark Plug Wires. I've had them for over a year now, they're pretty good.

Oh...and I also went with the AC Delco Platinums. I figured I could'nt go wrong with OEM parts. The one I had before these were Bosch Platinums +2.

oh, I'm sorry, I guess I figured a 95 jimmy would be the same as a 95 blazer. There is a Jimmy in that list. Is your engine vin number a W? If so, I dont see why 41803 plats wouldnt work. I dont know what to tell you, but I am sorry.

I understand, but realistically, you don't want to take a change like that.

Use what is meant for your engine.

Just to keep everyone updated, I just bought 41-803 delco plats for a 95 jimmy, and am going to do a tune up probably wednesday or so after class. I have not been able to track down the delco wires with the straight distributor boots. No one around here has them, I may just go with the autolite for the heck of it. I will keep you informed on how the new platinum plugs help performance.

Go to the dealer for the wires and don't install those plugs if they are not intended for your engine.

You are just asking for trouble.

no, they were made for my motor, and I got ac-delco plugs for it for 45 bux. Tune up day is wednesday, I will let you know how it turns out.

not plugs, I meant plug wires for 45 bux, and plugs costed 6 bux each. not bad. I also bought the ac delco fuel filter, and plan on cleaning the throttle plates, and redoing some cracked vacuum lines. And also balence and rotate the tires. should run like new when I'm done with it, (I hope).
