I know that this has been talked about MILLIONS of times....

I need a tune up and I am confused as to if I need copper or irridium plugs. Currently I have a cold air intake ( yes, open filter in engine compartment... looking for a way to shield it currently) and I would like to get a smaller pulley when I can get a scantool.

I think that the copper plugs are the way to go, but not 100% sure.

Also, what O2 should I get??

I went to my local Advance Auto store today to check on prices and the guy basically looked at me like I was an idiot for wanting NGK TR55s copper for my L67. He went on and on about how platinum is so much better and that copper is junk. He also said that there are alot of GPs that run around there with the platinums or iridiums. Then he told me that SOMEBODY was feeding me a line of BS and that copper is the worst for these cars, then I said that this information about Bosch being junk, copper is good, and that Bosch O2s are junk came from an online forum of thousands of members all over the country, even people in other countries. The guy still stood there acting like I was an idiot and that he was some sort of "spark plug / car god"

Looks like it is off to Auto Zone or Napa.

once again, I know that this has been talked about alot, but I just want to make sure that the answers I found will fill my personal needs.

I don't care if I have to change the plugs at 30,000 miles either, just want the best plug for my situation. Thank you.

Copper NGK TR55s are an excellent plug for a great price. tons of people here run them as do I, they're great. Gapped at .060

Oh. And that guy is just ignorant. Bring him here. Feed him to the gearheads.

Platinum is not the best by any means whatsoever and coppers are just fine. Some of the highest HP cars here run them.

Copper is fine. Platinums shouldn't be run with L67s. Iridiums would last longer, but my TR55s looked great after one year.

Ask the guy if he runs Hamsters or Mice.

or rice!
