does anyone really think these things are better than NGK IT-20s? they say 3 times better than iridium and 5 times better than platinum.

don't use iridium or platinum. the porcelain on the denso's have been know to brake. platinum plugs are a no no on our trucks anyhow. just stick to simple copper plug. i was recommended the ngk br7's for nitrous.
as far as zex plugs go, i have no idea, nor do i care. plugs are not going to give you hp.
