Spark Plugs Customer Reviews

Reviewed by Gerard S (Akron, NY) Reviewed for a 2010 Chevy Cobalt — 2012-09-05 09:18:57

Engine ran smoother immediately after installation of the new Pulstar Plugs. RPMs dropped by 100-200 revs at 65 mph. At this point, mileage appears to be improving; however, cannot say for sure until after running through a few tank fills. Science behind design appears credible. Note slight increase in acceleration. If honeymoon continues, highly recommend as well worth the price.
