AWeb80 Posted October 6, 2005 Report Posted October 6, 2005 Should I just get stock replacement Delco's or do any of you use the bosch platinum ones.... Will i notice any difference.....i've got like 40K on the plugs.... Should I look into iridium plugs? Price doesn't matter. Quote
sdwhite Posted October 6, 2005 Report Posted October 6, 2005 I've been told not to use Bosch Platinum 2's in my 3.1. Quote
Prospeeder Posted October 6, 2005 Report Posted October 6, 2005 AC delco rapid fires i hear are great plugs Quote
digitaloutsider Posted October 6, 2005 Report Posted October 6, 2005 Do NOT use Bosch platinum plugs period. Don't use anything Bosch if you can help it. Horrible products, and our waste spark system EATS up their platinum plugs. If you want a performance plug, look for Denso/NGK Iridiums. I'd really just stick with plain-jane AC Delco's in a stock 3100, though. Quote
93CutlassSupreme Posted October 6, 2005 Report Posted October 6, 2005 how many spark plug threads have we had lately? AC Delco plugs Quote
DOHCRagtopguy Posted October 6, 2005 Report Posted October 6, 2005 AC Rapidfire 8's are the ones I swear by. NO BOSCH PLATINUMS SHOULD BE USED!! Quote
badassoldspower Posted October 7, 2005 Report Posted October 7, 2005 Bosch is evil evil stuff I would go with some NGK's or Delcos Quote
gp90se Posted October 8, 2005 Report Posted October 8, 2005 since $ isnt an issue, go with NGK iridium tip plugs and let me know how the car feels after. we have run them in a couple cars and usually gives the car a little more kick, but havent put any milage on the cars yet. They are supposed 2 last 100k and increase mpg. but you really cant go wrong with delcos/ngks Quote
IBuiltMine-o1oo Posted October 8, 2005 Report Posted October 8, 2005 before i found this site, i put a set of bosch 2's in. the are fing sweet at first, but now i have noticed its taking an extra second to start the car...still runs good, and ive notice quite a difference in acceleration. My car had the original plugs in at 115k!! 2k on the bosch and time to replace! that was a waste of 30 bucks... Quote
pwmin Posted October 8, 2005 Report Posted October 8, 2005 regular delco's. it's easy to change them out, so i wouldnt go with platinums (iirc, rapidfires are Pt also). obiously, check your plugs for tracking and your wires for corrosion. Quote
AWeb80 Posted October 8, 2005 Author Report Posted October 8, 2005 I put the AC Delco Rapidfire 8's in and wow....can definatly feel a little more power top end....nothing huge but, its there....and throttle response and idle From ~2800-5000 RPM, there is more getup and go....of course I had ~40k miles on them, they still looked good, but it was only like $20 and a little time. Quote
pwmin Posted October 9, 2005 Report Posted October 9, 2005 glad you had a good experience with them. havent tried them in my gp, but they didnt seem to work any better in my camaro's old 305 Quote
DOHCRagtopguy Posted October 9, 2005 Report Posted October 9, 2005 Bingo-Another happy user of Rapidfire 8's. The first time that I put them in my LQ-1 I thought it was a brand new animal! The difference is amazing to me. Almost like the difference in my old 327 when I put in a Mallory dual-point distributor. Oops, I'm showing my age again. :oops: Quote
Prospeeder Posted October 9, 2005 Report Posted October 9, 2005 wow, i should look into those!! are the rapid fire 8's pricy? Quote
AWeb80 Posted October 9, 2005 Author Report Posted October 9, 2005 u, like 4.50 a plug i think....not bad IMO Quote
Prospeeder Posted October 9, 2005 Report Posted October 9, 2005 ih thats it, thats average i notice, so no biggy Quote
AWeb80 Posted October 9, 2005 Author Report Posted October 9, 2005 I dunno...I know they are sweet. Just got back from cruising our strip and the car feels great. Quote
mfewtrail Posted October 9, 2005 Report Posted October 9, 2005 wow, i should look into those!! are the rapid fire 8's pricy? Use AC Delco R42LTS in your TGP(stock plugs...about $2 each from most parts stores) or if you can find a box of OLDER Rapid Fire 8's(you likely won't find these unless you search ebay for a while....), then they're fine to use(the newer ones are platinum) "The small round tip is the new platinum version of the rapidfire. The old version, which had many small ridges in a cone formation on the tip, did very well in the TGP's. HOwever, the small round tip besides being platinum, doesn't offer as many sharp edges for the spark to fire from. It was one of the unique things about the rapidfire, also how it was named. Now its just a platinum plug. " I took that from the TGP board(a quote from Chris A., the platinum rapidfires aren't recommended for TGP's). Quote
THe_DeTAiL3R Posted October 9, 2005 Report Posted October 9, 2005 I'm gonna have to get some soon. Car was idling a bit choppy the other day, and it just doesn't have the power I think it should. I think I'll go with rapid Fires as well then. Quote
Euro Posted October 9, 2005 Report Posted October 9, 2005 are rapidfire 8's cool with a relatively stock 3.1? I mean Adam im not sure if your motor is stock or what... i need to change mine, my gas mileage=teh suxor and i wanna say my plugs are 116k mile original :oops: Quote
AWeb80 Posted October 9, 2005 Author Report Posted October 9, 2005 Eurosport94 My engine is totally stock...just k&N drop in and it has 114,500 miles. Quote
Euro Posted October 9, 2005 Report Posted October 9, 2005 ok thanks man...so im in the same boat as you Quote
DOHCRagtopguy Posted October 9, 2005 Report Posted October 9, 2005 I believe that Rapidfire 8's would be just fine in a 3.1. Yes the newer ones are platinum tipped. I can't honestly give an opinion on them I haven't used them yet. The Olds is due soon for a change, I'll let youse know. I recall paying around $4 apiece for mine. That was like 2 years ago. Quote
