[Bradley G]

What's your favorite spark plug ? I was using Autolite 103# 's before , anything better than that for boosted applications?

TR6's are the norm. However if you have a car that runs like ass with them the 103 Iridums are excellent and not to pricey.

Not boosted but use NGK TR6IX plugs (gapped at .035) for close to 140k miles now. NGK TR6 plugs are solid plugs for boosted cars.
