Anyone tried these plugs? Always had good luck with NGK so I’m tempted to try ‘em.

Haven’t you been successfully using Motorcraft?
Why change brands on a critical part where gapping has become an exact science?

 

[FanaticalKilla]

Because when I was reading, the only other plug that tuners recommend are these!

I change my plugs at 20000 and do not need the extra life of Ruthenium's. The iridium NGK 6510"s have performed fine in my 2.7. They do have a good rep!
I went to NGK as they do not play games with the part numbers like MC. KM

I’d save the headache and just stick with motorcraft. NGK is the supplier, but Motorcraft are built exactly to Ford’s specs.

Ford did not cheap out on plugs. They are constantly revising them.

The stock plug is already very cold.

I have them in my 16. They have performed flawlessly so far. I need to pull them and check the gap for wear but I am stock and put them in at 28 thousandths so it will be interesting to see what they’re at when I pull them.

My plugs at 70k miles. Motorcraft stock. I was very very impressed and did another set of motorcrafts 1 heat range colder. That was about 2k miles ago, ish. Full disclosure, I had a misfire on cylinder 6 today, first one since I changed my plugs to the last set 72k miles ago. Truck settled down after about a quarter mile from the misfire, was out of limp mode before i could take the next exit and is running fine now. Was also with a new tune revision so I am not sure I blame the plugs yet but it does give me a reason to pull cylinder 6 and share a couple pictures. Tomorrow evening. Current plugs all gapped to .028 in case anybody is keeping score. Also, ocured in 3rd at 45k rpm

I'll admit much of my thinking dates back to 1960's but back then with the copper core plugs re-gapping was largely a waste of time. Often resulting in short use after putting them back as the gaps quickly grew to be worse. Figured they took a heat set and after warming up to full temperature they went back to excessive gaps. Always replaced them if expecting to put mileage on, plugs even today are not that costly. KM

Just pulling them to look out of curiosity not for any other reason.

That is why I pull, check, but put in new. I figure why waste the labor on reusing old plugs. KM

 

[Tim_M]

I agree and will probably wait till there’s a really good reason to pull them. Time is a precious commodity and with three kiddos it is hard to come by so I try my best to not waste it.

OHH, small hands would be a big help! Especially on the rear passenger side plug. KM

Maybe one day but they are too young right now to get all in under the hood…9, 6, and 4. Oldest is almost there.

Many of us were in our teens when the transmission was invented…. 👴

Helping pull engines at 14 on the farm, funniest was when they didn’t get the timing right and the old International back fired through the carb. Burnt cousins brother in laws eyebrows clear off.

My Daddy always made me pour gas in the carb while he cranked the engine. I don't think he liked me.
