    1953 Hemi V8 Engine Vintage Spark Plugs

    I have a 1953 Chrysler Hemi V8 enginethat my Father and I put into a 1940 Ford Pickup, in 1958.. I have been buying the wrong spark plugs for my engine for over 15 years! I remember my Father showing me (30 years ago), that the original plugs did not use a gasket, like all other plugs use. I never could find the correct type, so I continued to buy the ones available. The Autolite AR82 Spark Plug do NOT use a gasket, therefore allowing the spark plug to go deeper into the Hemi cylinder heads, providing more horsepower, and better gas mileage. Thank you for the NOS vintage Hemi plugs! They work the way they were supposed to.

    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.

    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.

    I have the confidence these plugs will help my fuel econimy

    Five Star product: I installed these E3.40 plugs in my 1990 Ford pickup and have noticed an incredible noticeable ower increase, along with the 10.5 racing plug wires and new cap and rotor kit. I am hopeful they will also give me better fuel mileage also .

    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.
