Probably a little odd to be selling used spark plugs but I bought these on NGK's recommendation and they did not work for me, will not use them and hate to throw them away. Gapped them down to .024 (as per NGK), drove 12 miles to the track, made 4 1/4-mile passes and drove home. NGK said the engine would start, idle and drive better and it certainly did, but at full boost the engine felt flat and made less power. I am trying to push 900+hp and I am sure they would work good for someone with a DD making much less power.
