E3.68 E3 Premium Automotive Spark Plugs (8-PACK)

I installed these in my 2014 Toyota Tacoma (V6) and actually gained about 1 mpg. I check my mileage on every fill up and these have actually made a difference. It's common to 'feel' some improvement when installing new plugs because the old ones are usually ready to be replaced. The units I replaced had about 50,000 miles on them and the truck was running fine but the recommended replacement interval for standard plugs is 30,000 miles. I personally think this is overkill so I go 50,000-ish.These actually seem to perform in my truck a little better than the standard copper core plugs the manual recommends. I know this sounds like snake oil and a spark plug shouldn't make a difference but I'm about 3,000 miles into these plugs and they are consistently giving me about a 1 mpg increase. The truck seems to pull stronger so I can run a gear higher than before on the twisty, hilly roads of southern Indiana.I highly recommend these plugs.

Put these in when I did the motor. Did a lot of research on line and decided on the E3. Noticed a little difference but could be the new motor too. Still running these after 18 thousand miles and have had no problem, even when towing. Some people said they would not work in the Hemi, but they seem to be working great in mine. I also have 2 sets of iridium plugs if these decide to get cocky. They came with the motor.

Bought these for a nissan titan that really did not need them but I thought why not. After some reviews I thought I will try this out. They worked great for a couple of weeks and then I started to have a miss in my truck. Pulled coil packs and found one melted so replaced it. Today a week later started having severe miss on the highway almost did not make it home. Pulled the same coil pack found it totally melted. Then I pulled the plug and found the glass was spining in the metal socked of the plug the electrode in the plug spins freely and looks like it is about to fall out. Not sure if these have a warrany or not but this one plug has cost me two coil packs and could have cost me a engine. buyer beware. I like the idea of these but not happy with the results of them

My neighbor recommended the brand, I had them installed and sure enough, my gas millage went up.
