Has anyone run the E3 Diamnond fire plugs in their wings. They made a vast improvement in my car and I was just wondering if someone has tried them in their wings and what they thought of them and the results.

What improvements were made in the car??
What did they replace? How many miles were on the old plugs?
Thanks

Better idle quality, improved throttle response and lower emissions, proven by testing at local emmission shop here in Georgia. The replaced Autolite 25, which I have always used in the car. The plugs had 29,000 miles on them

I've been toying with the idea of getting a set of those E3 for my bike. If you've done it already, let me know if there worth the price.

I have done it in my car, the results were very noticable. I was thinking about doing it with my wing.

I haven't had the need to change plugs due to the low mileage, but I may go to Iridiums when I do.

I worked for a company that made spark plugs and at that time there was no difference in any brand of plug ! I made every kind of plug you can name and all of them used the same bonding material as the other , for instance Autolite and JC PENNY plugs were the exact same plugs along with SHELL , towmotor , ETC ! We had two base materials used in them , your regular plugs use a copper & glass mixture to bond the center electrode and terminal inside the insulator or the resistor plug uses a RESISTOR POWDER to bond the center electrode and terminal . Prestolite and Autolite were made side by side usiing the same materials . I donated my vehicle to the research and development team to test different plugs for the years that i worked there and i never saw any difference in any of them . My opinion is one is as good as the other if you get the correct heat range plug !
