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.

e3 easy pick

Summit RacingSummit Racing Verified Purchase

i run these in my daily driver c10 and it help the old dog 350. Run them in my pro street 81 c10 and they have a slight gain over other plugs as well as a longer life with the larger cams. And they work great in my old 64 gto with a stock 389 they just dont come with the little washers got to put them on yourself

Good product

Summit RacingSummit Racing Verified Purchase

I have not driven the vehicle since I have installed the plugs, so I can only comment on the look, feel and quality of materials used (very good). I find that the diamond fire technology seems to live up to its name so far. Once installed, the truck fired up much easier than it had previously, and the throttle response was great. The only drawback that I found was that you could not double check the gap if you use a circular type gap tool. A standard feeler gauge is necessary. ...read more

Could feel the gain in power as soon as I started my truck. 2 to 3 miles per gallon better on gas. This is a great product. Will buy again
