I do. They seemed to smooth out my idle a bit. I can't say they produced any more power, but my car does run well with them.

Re: Iridium Plugs whose got'em

I have the NGK BKR7E-11 Iridium plugs installed. I called NGK tech support hotline and told them the modifications I was installing and these were the plugs they recommended.

So far they've worked great - I pulled one after 10,000 miles for inspection and it was burning clean......

Here's a great read from the NGK website.

We install them on all the cars we work on as the factory ones are not the best for performance. Much better idle and throttle response, nothing substantial as far as power is concerned.

I run the zex plugs 2 degrees colder. Not a noticable difference but Nitrous and platinum dont mix.

Re: Iridium Plugs whose got'em

After doing the mods to my car, I re-gapped the stockers to .034 and the car runs great. I don't see where buying different plugs does any good.
