Condition:
Instead, it would require an entirely new approach in the design of the plug's electrode to improve the ignition of raw fuel inside the engine's combustion area. The first step would be to get rid of the antiquated J-wire electrode.

Never dissapointed!
I've used these in a few of my project/daily drivers and always good results! I ran them in my 83 Chevy both in the worn out 305 and hopped up 350 that replaced it (same set of plugs) and never changed them over 4 years without issue. I also ran them in a 97 Thunderbird v6 and avg'd 1-2mpg improvement in both. On the 97 being computer controlled I did have to disconnect battery to reset the ecm to make it run right but smoother and better than ever afterwards. I just installed this set in my 79 Mercury Cougar which has already had upgrades like HEI and 4bbl/intake and right away noticed smoother idle and better throttle response! These have always worked great for me, but if your car has ecm/fuel injection reset the computer after installing, just like you would (should) for a sensor replacement!Verified purchase: YesCondition: New

Responsive
I had iridium type Motorcraft spark plugs which I paid the same or more! After installing EC3 spark plugs my idle was smoother and the engine was so responsive on acceleration, you could hear the difference!Verified purchase: YesCondition: New

Little more
Yes a little more I could tell the difference after tune up cap & rotor E3 plugs and wires . My truck with 4.3 ran good before doing so . Live in WV hilly so not hard to notice the first ride an test I could tell and hope to improve gas mileage too ! But I like 5 years 100,000 mile warranty inside the 4 pack box . Hope they make your run better also ! Drive carful 😎!Verified purchase: YesCondition: New

Only Spark Plugs I Use
I love these spark plugs!! There's nothing like a strong ignition system. I been using these plugs on all my vehicles for at least the past 5 years, and not one fouled plug since. With a good coil, plug wires and these plugs, you will be amazed at how much better your vehicle will run!! Strong ignition components are key to a well running engine. 5 stars all day, all night!!Verified purchase: YesCondition: New
