wish this would have been posted a few days ago I just changed my plugs to the 534's last weekend and can't justify the change so quickly? What do you guys see as the main difference between these plugs making them run so much better?

Were these back to back runs? I have a hard time believing this. Something else must of changed. If this is true we would be using them in terminators and gt500's. I understand going to a colder plug but never have I heard of gaining 30rwhp with just spark plugs. Not to mention only 6!

Bullsh....

This test and yours don't jive. You are testing a different plug but i doubt the silver gave those huge gains.

On another forum guys are saying they have a very noticeable difference. Not sure if its that high of numbers or not, but gonna be good enough for me to try them.

If they have a superior spark, they may help with the fall on face condensation problem. Switching from SP-528 gapped at .035-.040 to SP-534 gapped at .028-.032 has helped some, so who knows.

Ya, kinda thinking the same thing. Unless the stock plugs were 100k miles and completely worn out. Then ya, there would be 30 hp difference.

yea, this sounds like a folk tale. If that was the case, they wouldn't be that cheap either. 30hp/tq or 30 anything would be 300+ and people would be putting them in anything that would take a spark plug. that includes civics and lawnmowers. haha

on the other hand, a few people have responded and said it made idle smoother and better throttle response.
