I've heard mixed reviews. Some say no difference. Some swear by them and say they add 2-3 MPG. Others said they didn't even work in their car and they had to put the oldies back in. Any of you running E3's in your MINI? Notice any difference (good or bad)?

Thanks!

 

Nope no E3, I had these NGK BKR7EQUP, then switched to NKG Iridium IX BKR6EIX, next time I want to try Brisk Racing Silver plugs hear good stuff about them..

 

If you believe Horsepower TV the E3 plugs are the best thing since the internal combustion engine. It's an eye brow raise for me. They are a sponsor, so of course they are shown in a good light

 

firenewt, I saw that too. And I thought the same thing. But after they did that 'ignition box' thing or whatever they called it and compared the spark, I was less skeptical. Idk, I just can't decide.
