Going to replace my spark plugs in my 05 f150 5.4L 3 valve. Does anyone recommend one over the other? Also how well does the new E3 plugs work?

 

E3's - not well, as it hasw recently been revealed - see end of this thread: https://www.f150online.com/forums/ot...ark-plugs.html. Sad - as they indeed looked promising. I feel bad for Sam too - he really put his heart into this.

AND - props to Thomabro for posting this and revealing the problem first: https://www.f150online.com/forums/v8...4-problem.html. We are in your debt.

Short Answer - Motorcraft SP507 or SP515. Champs or Brisk if yer willing to try something different and/or you really, really do not want to run another 2-piece plug for the rest of yer life ...

Time to get comfortable with Advance Search, sir. It will serve you well. (But - I will continue to try & help if required).

Motorcraft...

 

I have a new long block going into my truck, and I also was wondering about what plug to run.

I initially thought the 1 piece Champion was the no brainer. After searching a bit on here, I found that to be not true and decided to just use a brand new set of double plat Motorcraft plugs with plenty of anti-seize AND brand new COPs to make sure everything is kosher in the ignition department.

 

Very interesting on the E3 plugs. Anyone ever run E3's in older cars, like 1967 ford fairlane? Someone asked me about puting E3's in a 67 fairlane with a 351C. I said I had have no idea. Never tried them before.

 

I am running E3's in my 2006 F150. I currently have no regrets in running the. I am pretty pleased with them.
And they do have a 5 yr 100k mile warranty plus a Customer Satisfaction Guarantee on them.

I have also ran E3's in my 2001 Blazer too. Had decent results.

As far as a 67, I don't know. My neighbor has one is his carb lawnmower? but now where near the same as a car. lol.

 

I use brisk racing plus with zero issues I don't know if they make non blower plugs

 

Yes they do make brisk plugs for nonsupercharged truck that's what im about to order for my truck.

 

Brisk plugs are a great alternative....
But fall short of the Motorcraft platinum electrode design....

 

The corollary position would be:

- Brisk shrouds the arc less
- Brisk is easier to gap
- Brisk silver requires far less voltage to fire (silver being far more conductive than platinum)
- Brisk is a one-piece design
- Brisk does have a compatible heat range plug (sort-of, lol)

- Brisk electrode does wear faster though....

that one....

 

We have had 3 or 4 members post that they had misfires with the E3's after a few miles and they were replaced.

If you run Brisk, you will be changing them every 25k.

Best plugs for your Fairlane are stock copper Motorcraft or Autolite.

 

I always forget about that. Also are the motorcraft cop's better than the MSD's?
