E3.68 E3 Premium Automotive Spark Plugs (8 PACK) - 100K miles / 5 years Warranty

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.

Never tried the product Mechanic told me they were garbage plugs and he refused to put them in. My problem is it took me several weeks to get a refund? But yet it took you less than 30 seconds to take my money 🤷‍♂️

Ran great in truck, installed in 6.4L HEM.

Working good
