92Cutlass4Dr Posted April 3, 2003 Report Posted April 3, 2003 I'm planning to replace spark plugs tomorrow, and i want some quick recommendations. i don't need anything special, my engine is totally stock. I've heard here that Bosch Platinum are bad because they deteriorate with the waste spark. So, how about NGK or just basic AC Delco? Thanks in advance Quote
JS91Z34 Posted April 3, 2003 Report Posted April 3, 2003 Double platinum plugs dont deteriorate in the waste spark system. Some manufacturers actually require double platinum plugs for warranty purposes. I put NGK's in a couple of my cars. I have double platinum in my Z34. Quote
stlunatics2oo3 Posted April 3, 2003 Report Posted April 3, 2003 ac delco rapid fires are awesome don't get autolite they suck Quote
BlackSunshine Posted April 3, 2003 Report Posted April 3, 2003 Basically, platinum spark plugs are good for long life. The problem with them is they give off a weak spark because platinum is a poor conductor. The AC-Delco plugs are the best ones for your car, if not them then Champions are good as well. :guns: Quote
NOHC_WBody Posted April 3, 2003 Report Posted April 3, 2003 I've used AC-Rapidfires in all my cars since I found out about them. I'd go so far as to say I swear by them. Quote
cutlassdude96 Posted April 3, 2003 Report Posted April 3, 2003 I got Rapidfires in my too. GO with the rapidfires 8) Quote
PJB Posted April 3, 2003 Report Posted April 3, 2003 Ive always used Autolites in my truck and had no problems. My car has new Autolites too. Quote
NeverSayDie Posted April 3, 2003 Report Posted April 3, 2003 My Bosch platinum 4's were still going strong after 60,000, but then I took my heads to the machine shop with out taking them out...they're kinda flat on the electrode end now I'd go with the Delco's though. I couldn't tell any difference with the $40 anyways Quote
godofthunder Posted April 3, 2003 Report Posted April 3, 2003 Ive got ACDelco Professional Platmium plugs, really nice. I replaced mine, and the wires with the Professional serries wires over the winter Jon Quote
musthavemuzk Posted April 3, 2003 Report Posted April 3, 2003 ok so which rapidfires will work? mine is the 3.1 in a 90cutty and where can i find them? Monty Quote
cutlassdude96 Posted April 4, 2003 Report Posted April 4, 2003 any parts store should carry them, you want #6 plugs Quote
ismellrealbad Posted April 4, 2003 Report Posted April 4, 2003 i have brand new autolites in mine. they seem fine, although next change i will get AC delcos based on the feedback from here Quote
92Cutlass4Dr Posted April 4, 2003 Author Report Posted April 4, 2003 Replaced the plugs today, but i decided to be cheap. I went with the AC delco stock plugs. i might be selling the car with in 6 months and since the car is stock, i figured why bother. I also replaced my front speakers (JL Audio TR 4" speakers) and went tire shopping. it was a pretty productive day. Thanks for the advice. Quote
