good experience. Entered 67 Mustang 302

Noticeable difference in performance and smell of smoke and gas. They sent me the wrong plug and the supplier kindly refunded my money. All in all a good experience. Came in '67 Mustang 302 with Edelbrock 600 CFM carburetor and MSD ignition box.

Pros
  • Free for educational purposes
Cons
  • Not sure

Great for spark plugs

I use these E3 brands on all my petrol engines, they work great. This candle went to 91 Ford f150 with 300 6 cylinders. Seems to run smoother now

Pros
  • Great for a small house
Cons
  • Modern

E3 for spark plug and wire win

I didn't think I'd notice a real difference in an Obs Ford truck but it's quite noticeable. Sent and delivered quickly too which is also a plus :)

Doesn't work as advertised, truck drives terrible

My 1992 Ford F-150 4.9 liter engine had to do a lot of miles to set up but otherwise worked great . Decided to try them out to see if I could get a little more power or better gas mileage than they claimed. They've been in the field for over a month and since the start of the installation the trucks' acceleration has been slowing down and idling horribly overspeed. I am very disappointed as they cost twice as much as standard plugs and now need to be replaced. The cover, rotor and connector…

Pros
  • Good product for the price
Cons
  • I vaguely remember
