I'm looking for e3 spark plugs for my 92 300 I6 but can't find thm anywhere. Does anyone know where I can order thm? Are the plugs for tht motor the same as the 302? Any help is great. Thanks!

 

Go to a Ford Dealer and order 6 spark plugs BSF42C, calibrate to .042"

 

don't wast your money on E3s I have returned more of them then I have sold!

 

They might work better on other applications but certainly not ours. Any spark plug that is not copper has a hard time working in our engines.

 

Skip the snake oil plugs. They are just like split fire etc. I also read that the E3 is china made junk.

Stick with Motorcraft of Autolite plugs.

 

i asked about those when i was in oriellys one day.....the guy told me to stay away from them....lol, not even for the lawnmower!!, they are pure junk....

he is a ford technician for his day job, and he said the same thing ive heard here several times....motorcraft or autolite are the only things to run in these trucks

 

not even for the lawnmower lmfao!!! I use copper core in my 5hp push lawnmower it works fine. Yes our truck don't accept crap that is why they don't work correctly.

 

I too work @ Oreillys, when we had a spiff on the E3s I sold 4 or 5 sets.

late 90s Taurus 2000 miles and the car would not run, all six plugs looked bad 2 of them the center electrode was melted right out of the insulator tip.

98 Chevy 5.7 would not even run, brought plugs back in 6 hours.

Honda had a miss after 2days, the ground electrode WAS GONE!




autolites are at the top of the page, so that's all the parts guys think they can sell.

 

Wow thanks guys. I'm glad I asked before I spent that much money. You guys are awesome.

So what would you recommend to be a good plug? I don't like runnin junk!
Thanks again everyone

I'm glad you didn't waste money on those. Use the factory type Motorcraft or Autolite plugs.

 

Motorcraft BSF42C

 

I know the point has already been established, but just for reference, my friend ran some E3's in his 300, and when he went to start it, for the first time, nothing..........

I run normal Motorcraft Copper Cores, and now my friend does too.

 

E-3s have no place in ANY engine!...........A guy I know installed E-3 marine plugs in his 150hp Mercury 2 stroke outboard, ran for about a hour.....then started progressively running worse, until he was towed back to the boat ramp by the Coast Guard.........Put the old plugs back in, ran with no issues............garbage.

 

I ask myself this question. "How in the world did they make it to the market"? Company should be sued. I mean cmon. They won't even make a lawnmower run.
