Review on π₯ E3 Spark Plugs E3.74 Premium Automotive Spark Plug: Unleash Your Engine's Potential with DiamondFIRE Technology! (Pack of 1) by Daniel King
A very happy customer!
Lots of reviews for and against this product but I was recently disgusted that the service station was trying to bill me for FoMoCo forks and decided it was time to get back to work with mine . I'm glad I did. I learned 2 things: 1) The Ford Coyote 5L engine is the easiest engine to change spark plugs ever! 2) These plugs are working great so far. By doing nothing on the dyno, I feel a steady improvement in my acceleration and a slightly lower rpm at cruising speed, which I attribute to the maximum power conversion with the plug it advertises. Great candles, glad I risked it!
- Fingers crossed
- Something else
