I am impressed with the plugs. I went from burning 3/4 of a tank of gas to only burning a half.

Best Plug I have Ever Used

Summit RacingSummit Racing Verified Purchase

Installed these plugs in my '72 Chevelle and they made a huge difference. My carb tends to run alittle rich and would foul my delco plugs occaisionally. I used these and Wow what a differance. I will not use anything else.
