Hello:

Doe's anyone have any feedback on Iriduim, or Platinum plugs compared to the stock? I am getting ready to change plugs, and I am considering Iridium plugs. Any pros and cons would be appreciated on both iriduim and platinum.

Thanks

Cons... Price
Pros: Better fuel economy, better response, less resistance, less emmissions.

Go with Iridium, you'll be happier with them. DO NOT use the multi electrode platinums from Bosch or such. They will **** up your engine.

I am using NGK IR's... i felt a little extra oomf after installing them and a smoother idle, but i also replaced the plug wires at the same time.

Maddog. Why would you replace the plug wires so soon. Also what brand of wires.

I would not touch the wires...no reason too...

aaaaah it says Taylor plug wires. (or am I hallucinating? Lots happened to me back in the '70s )

I read in the below response that the Iridiums are better, the other spark plugs are junk, and will foul up the 5.7 Hemi engine. Could you please explain why? I have bought 16 of these Bosch +4 and was going to put them in. Please advise.
