Great Product
I just received these plugs and put them in my 2011 Civic 1.8. I was in the 90k mile range and I've been noticing a gradual decrease in power over time. I put my new plugs in yesterday and instantly noticed a gain in power.

Throttle response is back and the slight delay when I jam on the throttle is gone. I haven't had them in long enough to see if I gain any mpg, but I'm sure I will. I saw these plugs on Horsepower TV years ago when they first came out and they were raving about them. I'm glad I purchased these plugs and I've been talking them up to everyone.

For something you're only going to replace every 100k miles it's worth every penny.

Also HP TV had mentioned a slight HP gain like 2-3hp with these plugs. In a big v8 you probably won't notice it, but in a 4 banger that you use as your daily driver you'll notice the response instantly.

Amazing Product
I owned a 1985 Toyota Corolla GTS and I was recommended these plugs. I was somewhat skeptical at first, but once they were installed, my mind was completely changed. These plugs are amazing. Better throttle response, increased MPG, and I never had a fouling issue with them. I will run these plugs in everything that I can. Would recommend to anyone.

Fantadtic Product!
I used these plugs in my 1986 Toyota Mr2 and they worked wonderfully. Right away I noticed more throttle response than with the recommended factory plugs. Also quickly noticed a 4-5 mpg increase in my fuel range. Definitely satisfied with E3 products and will use them in all my future automotive applications.
