Spark Plug Advice, please... E3 Dimond Fire plugs

Hi all,

Can you share your wisdom on the E3 dimond fire spark plugs.... vs say ACdelco plugs I run in my 38 Willys BBC....

Do the E3s really give you better performance on the strip....@4X the price of the ACdelco plugs??

Thanks!

I havent personally run them, but i know a good many who have tried. Their take on the matter is that they are nothing more than snake oil.

What kind of ignition system do you have? MSD recommends inexpensive, standard plugs be used with their ignition systems.

I refuse to believe that accel is the only manufacturer of shorty spark plugs, can somebody give me good part numbers for some shorty header plugs for 283(MSD equipped) that are not accel or arnold lawnmower plugs.


thanks ,

The newer AC Delco plugs are shorter than they were 15 years ago. Atleast they were for my 93 chevy, they clear the headers fine.

I bought a set of diamond fire plugs and the motor ran like crap.
snake oil is an understatement!
All plugs are the same (they all create the spark).
save your money
I did notice a difference through running Iridium plugs though.

Fast 79 Malibu says the NGK's are the same length as the Accells and are much cheaper. Check this thread>
Shorty Sparkplugs
Just get the parts store to look up your application for part #. NGK's are very good plugs.

I've never tried the E3's but did try the Splitfire 2V & 3V split type and all they did was enhance my engines slight detonation problem. LOL! I asked the ?? on here (do they help fuel mileage) and got the same (snake oil) response. LOL! So I will agree just a gimmick because the Splits didn't give me anymore fuel mileage
