Default Spark Plugs.....Hmmmmm

Alright...My buddy tells me that platinum is not good for the bonne, and I have also learned that Bosch is garbage on the bonne, but what about Irridium????? I know AC-Delco Makes both Platinum and Irridium plugs. I was looking at the performance plus plugs and they look decent if it wasnt for the $5 price tag per plug.... So what do ya guys say about Irridium???

iridium is excellent. delcos, ngk, yep, they're all good. but honestly, TR55s are excellent for a low price plug. some of the highest performance cars here run them.

Never run Platinum in any Forced Induction application. Turbo, Nitrous, or Supercharged.

Moving to General Chat. Spark plugs are a tuneup item. There is no performance gain advantage other than to re-gain lost power after spark plugs begin to degrade.

The main difference...one is platinum and one is not. TR55s are better for SC'd cars. Either one would be fine for your car.

The platinums will probably last longer but the copper'* are cheaper...it all comes down to how often you want to change them. I highly doubt you'll see any performance gain over one another. I prefer to go with cheaper plugs and more frequent changes.

As stated, you won't see any real performance gain, so no plug is "better" than the other in your case. If you have old plugs, either one will be an improvement. Any "gains" from the plugs will only be what was lost due to old plugs.

Do a search. There are probably 76 million posts about "Why can't I use Platinum plugs in a forced induction car?"
