e-3 & Me

I have a mildly modified sbc, in an old El Camino. I didn't pick up 100 horse power or anything like that, but it DEFINITELY has more power, and a smoother idle. They are pricey, but still a good value.Read full review...

Greatest spark plugs on the planet

I've used e3s on everything from my toyotas, chevrolet to lawn mowers.
They are the most dependable, cleanest burning gas saving plugs money can buy. Never had a bad one.

Will not change your world but will pep up your engine.

I can't vouch for all the claims made about these but I can tell you they made a small noticeable difference in my engine, all for the better.
