NGK TR6 plugs FTW.

In my Ecotec I tried Iridium's and Super4's, complete waste of money. Go genuine or any mid-range product from a respectable brand.

If "performance plugs" were ever to make a difference it would be in a very high revving engine, which these are certainly not.

I have LS1... would NGK iridium plugs make any difference... at least cleaner ignition & better fuel economy.

What do you guys think of "Autolite" plugs?

what about Denso Iridium Plugs?

They wont make any difference, just use the TR6's.

These are the best plugs of all, they are better than NGK, Toyota stock and use these, but are expensive, save your money and just use the standard plugs. You will not notice anything, listed plug has right design ,reach etc. Only use these plugs if you only want to change them every 100,000. Champion also have an iridium, they may be cheaper than the other 2.

Autolite more common in America as the Nascar sponsored plug, i have seen a few people mention they are not that good. Brisk, Atomic and Silver plugs seems to be a new fad as well and may need some looking into. http://www.e3sparkplugs.com/technology.htm
