"I found that there may be a very slight increase in fuel milaege. There is a noticable increase in power, especially at the low end. However I did notice that there was a raised ring around the seat of the plugs, that I hope isn't going to damage the seats in the engine." —Randall N from Whitefield, NH bought a Pulstar Performance Series Spark Plugs for a 2000 Pontiac Firebird.
