Installing a new long block 460 in my project Flareside. What plugs is everyone using? By this I mean brand. Let your voice be heard!!

 

I use E3 spark plugs in my 400
Pretty good plugs if you ask me

 

I put Ford in Ford (Motorcraft).

 

Autolite for me in my 400. A good plug in general, works well, cost effective and if Autolite can't make a plug to work in a Ford engine who can!

 

All the car makers spend millions of dollars designing and testing engines. They usually recommend their brand of spark plugs. That should be enough evidence of what spark plug to run in any engine.

*I voted Autolite...

 

WOW! Nobody chose the option to call me an idiot. I am amazed. Thanks for the replies, keep 'em coming.

 

Back in the day, in my old F250 460, I ran Bosch Platinum.

Now I run Ford MotorCraft - like the book says!

 

WOW! Nobody chose the option to call me an idiot. I am amazed.

Looks like someone broke the tend- wasn't me.

 

I run Autolite.

 

I use Autolites but am curious about E-3s.

 

I run NGK's.

 

Autolite, NGK, or motorcraft all good plugs. Running NGK at the moment no issues.

 

Autolites, i have a bunch of NOS "Made in USA" Autolites on hand, i'm not sure what brand i'll use after this supply is exhausted...

the new Autolites are made in China and the quality leaves a lot to be desired when compared to the old American made Autolites.

 

I did use some E-3's for a very short time in a '87 Grand Prix, but had engine trouble and sold the car before they had a good test.

 

I use whatever I can get my hands on and won't make my wallet want to run away from me.

IMPO, spark plugs are really all the same... if they're making a spark, they're doing their job. I'm not paying out $10 per plug just cause it says "efficient" on the packaging...
