cryptnix Posted August 16, 2004 Report Share Posted August 16, 2004 So I hear that these plugs suck royal shit. I also heard that these are only good for cars that run or at least they need premium to not misfire. If you can make sense to what I'm trying to say please inform me of why these are bad plugs to use in our cars ... Quote Link to comment Share on other sites More sharing options...
sl3196 Posted August 16, 2004 Report Share Posted August 16, 2004 I had autolite double platniums in my cutlass and they never gave me any problems. Quote Link to comment Share on other sites More sharing options...

sl3196 Posted August 16, 2004 Report Share Posted August 16, 2004 Just don't use splitfire! Quote Link to comment Share on other sites More sharing options...
cryptnix Posted August 16, 2004 Author Report Share Posted August 16, 2004 well needless to say i notice a performance increase when i run premium but then thats just a higher octane so its obvious the fire is gonna burn hotter ... stupid question but the only thing that stands is its price, but does it do anything to the motor?

Brian P Posted August 16, 2004 Report Share Posted August 16, 2004 stay away from anything BOSCH especially the +2 or +4's that make outrageous claims but do nothing of the sort. Platinums are fine preferably AC's or autolites but it's never a good idea to keep them in for 100k like they claim. More like 50k tops. I always run resistor AC plugs in all my cars cause I can't get myself to not touch the ignition components for more than 30k. Meaning if I used platinums I'd still be changing them at 30,000-ish miles Quote Link to comment Share on other sites More sharing options...

93CutlassSupreme Posted August 16, 2004 Report Share Posted August 16, 2004 platnums arn't worth the price they loose their gap just as quick as coppers, unlike they're claimed to do Quote Link to comment Share on other sites More sharing options...

DOHCRagtopguy Posted August 16, 2004 Report Share Posted August 16, 2004 The Bosch platinum plugs don't work well on our cars because of the dual-spark cycle. It fires twice, once on power stroke and once on the exhaust or waste stroke in order to decrease emissions. I would recommend AC Rapidfire 8 plugs, I've been running them in both of our LQ-1 motors for a couple of years now with no problems.

mgenin Posted August 16, 2004 Report Share Posted August 16, 2004 I have been using the Bosh Platum 4+ plugs in both my Toyota and my Lumina 3100, and you really notice the difference. Some people say that its just better to stick with regular plugs, because of the price and you should be removing them every 50, 000 km, so they dont seize up or rust. Just remember, ALWAYS put a copper anti-seizant compound when installing your new plugs, and ALWAY finger-start your plugs, especially when going into an aluminum engine head.

White93z34 Posted August 16, 2004 Report Share Posted August 16, 2004 and ALWAY finger-start your plugs, especially when going into an aluminum engine head. so how would you go about doing that on the LQ1? Quote Link to comment Share on other sites More sharing options...
Brian P Posted August 16, 2004 Report Share Posted August 16, 2004 I have been using the Bosh Platum 4+ plugs in both my Toyota and my Lumina 3100, and you really notice the difference. What do you mean "notice the difference"? Notice the increased driveability problems, or what? I personally think you see nothing more than placebo, as BOSCH plugs work so poorly on GM ignition systems, that the mechanics at my job outright refuse to put them in. They lose $ when the cars they work on come back w/ problems. I can't speak for your Toyoka, however. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted August 16, 2004 Report Share Posted August 16, 2004 We put the Bosch +4's in our Grand Am back when we still had it. The thing ran like ASS. No lie. Lots of hesitation. Threw Rapidfires in there and it ran perfect. However, my freind put them in her Honda and it runs great. Go figure.. Quote Link to comment Share on other sites More sharing options...
Manny Posted August 17, 2004 Report Share Posted August 17, 2004 The spark from our GM DIS coil pack is too “hot†for Bosch platinum plugs. The extremely thin center electrode actually recedes into the ceramic insulator after a few thousand miles, and the car begins to run like absolute “chitâ€Â. I read this on a website somewhere, and I didn’t believe them until my car started running really crappy and I pulled my plugs to see for myself. Fouled each and every plug. Visibly worn beneath the center electrode. I replaced them with regular AC resistor plugs and cured the issue. If you must have a platinum plug, go with something that has a thicker center electrode. I tried Champion Double Platinum and didn’t have the same trouble associated with Bosch. Personally, I like Champion Gold Plus. Quote Link to comment Share on other sites More sharing options...
