Review on 🔥 E3 Spark Plugs E3.74 Premium Automotive Spark Plug: Unleash Your Engine's Potential with DiamondFIRE Technology! (Pack of 1) by Shane Sanchez

So far so good, 2016 Ford Fiesta set to automatic. It's been a few weeks now and the car drives a lot better, seems to have more power and has helped with gearbox issues where my car was struggling to shift on time and fuel economy seems a lot better too. Have it in collaboration with Wix's new air purifier. I have to say that when I first put them in when the car was still hot, I put them in too tight and when I first started the car after the 1st time after fitting the car has vibrating like crazy and sneezing and driving it was difficult. So I parked the car, unscrewed the spark plugs a little, and then tightened them back up with less effort. After that the car started and runs normally. So if you have this problem in this or any other machine, just try what I did. I have also used electrolysis.
