Motorcraft
SP-534

 

[reynolds243]

the OEM SP-534 work just fine as that is what most guys are putting in and you can find them at Oreilly for like $3.99 a plug

Frankly SCAP probably knows which plug is best better than anyone. I just figure since the rest of my engine is stock, I am sticking to Motorcraft.

My truck only has 37000 miles. Is it normal to need to replace so early?

 

[nitetrain5]

Sorry it's a 2012 also

Mine has 12K on it. I have seen so many stories on here, I have been planning on finding time to re-gap mine for months. I just went ahead and bought new ones to swap out. Only cast 5.99 each at the stealership.

Is seems someone at the Ford factory was using the plugs to open beer. The reported gaps on stock trucks are pretty ridiculous.

Turbo vehicles eat plugs. They're pretty inexpensive to do yourself.

The best plugs are the ones you chose.

I replace every 10k miles.

I'm using the MSD plugs, and I think they are great.

 

[Rio94gt]

MSD plugs here gapped @ .025
Of the 4 plugs I have ran I like these best so far. 1/4 mile will tell for sure.

Is it normal for ford spec to be .32 but when you pull the plugs they range from .35-42?


Btw mines a 2012 with 40,000kms

Been thinking about buying a set of plugs for mine, upper rpms it has a slight stumble and power delivery isn't so smooth. Anybody going with a colder plug for the higher boost from the tunes? Or has any tuner notice a difference tuning with a colder plug?

Did you check/reset your gap before you loaded your tune?

 

[taubr unit]

Yea, gapped all mine at .028. Both mpt and let tune idle rough so I don't think it's a "bad" tune. Its not missing at idle, just a constant roughness, lol, like it has solid motor mounts. I have around 14k on the truck so I'm up in the air about the plugs.
