BEST plugs ever. I put them in every car.
I bought these plugs to try out years ago. Since the very first set that is all I ever buy now. These plugs are the best money can buy. They work amazingly. I get noticable increase in power. Plus my gas mileage goes up better than any other plug I've ever tried. I have put them in everything from my 04 & 06 Dodge Grand Caravan to my 04 & 07 Jeep Liberty also my 06 Cadillac STS & 04 Chevrolet Avalanche. These are just a few examples of the vehicles I have used them in. I can say I am an E3 spark plug customer for life and would highly recommend them to anyone. I hope this was helpful. I just wanted to tell people how Awesome these spark plugs are. I can also say that they hold up over time as well. What a great product.
What kind of vehicle do you drive? 2004 Chevrolet Avalanche. 2006 Dodge Grand Caravan. 2007 Jeep Liberty
