^^^^ what he said. Gap them to .050 Always check the gaps on all of them, regardless of what they say they come gapped with from the factory.

Those plugs and that gap are perfect for a bone stock engine, all the way up to a fully built 454ci with 650 RWHP.

You have to use different plugs and gaps when you start spraying nitrous or going turbo or super charger.

just get the ngks that what most of us use. The gap needs to be at minimum .45 to max .55.

I ran the NGK TR5's in my 382 gap @ .035 with 11:1 compression. This is what MTI put in, when they built this motor. Plugs always looked great, and pistons tops looked brand new, when I tore the motor down. Motor had alittle less than 30,000 miles on it.
