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
