https://amzn.to/1VwDSw5Torque plugs come at least 20 lb-ft: There space varying institutions of think on this one. The consensus seems to it is in though that the factory spec (approx 13-14 lb-ft) for the spark plug is also low which reasons the plugs to loosen over time and evenually spit out of the engine. FordTechMakuloco recommends 20-25 lb-ft and also others swear by 28 lb-ft. In mine opinion anything end 20 lb-ft is great because you"re currently 50% greater than the factory spec. Ns installed in between 20-25 ~ above mine. None of the manufacturing facility plugs were loose with 110K mile on the engine with original plugs. Because that the record, the factory Ford shop hand-operated torque spec for spark plugs is 9-20 Nm or 78-176 lb-in (pound inches not pound feet).Spark plugs: please only use Motorcraft plugs. There room "fancier" spark plugs ~ above the market yet these engines seem come run ideal with Motorcraft plugs so perform yourself and also favor and also stick through them. The persons I used were the Motorcraft SP479Coils (COPs): The ideal coils to use if you have to replace one is Motorcraft, yet they are really expensive. Beware cheapo aftermarket persons as most of them will not last prefer Ford/Motorcraft. Personally I would certainly not introduce replacing every 8 coils just because you"re changing plugs, they"re no really a maintenance item like plugs are. Yeah they carry out wear out and also fail yet I would recommend you find the one coil that"s failed and also replace the individually v a high quality part such as Motorcraft DG508Spark plug boots: If you uncover a cracked or split boot down where it meets the plug, you should try replacing just the boot instead of the coil. The boots come off and also they"re prefer $5 so try that an initial to watch if it resolves any kind of misfire you could be having. I doubt a many of human being would blame to the whole coil if they observed the break-up boot. The boots is cheap and also easy to replace. Also, placed a little dielectric grease in the finish of the boot once re-installing. It"s not crucial to to fill up the finish of the boot, simply a quite moderate quantity is all that"s needed.Start with: part folks imply to start by law the hard plugs first, ns say begin with the basic ones an initial so you gain a feeling for the process. I actually adjusted the plugs in order from 1 v 8, possibly I"m OCD

As you can see, spark plug #1"s electrode is worn down but the rest are actually pretty good. I think the #1 worry was as result of an exhaust leak. Once I purchase the van it was leaking from the former of that exhaust manifold (one broken stud) and I don"t know how long it was favor that. I"ve because had that fixed.I had actually one plug the wasn"t coming out nicely (#4). Over there was significant resistance once I to be unscrewing it. If you find that, stop. Run the plug back down tight, climate loosen it about 1/4 turn. Put in 1/2 teaspoon of carb cleaner and also let the soak (ideally overnight). I did that and also then I worked it earlier and forth the following day and got it the end no problem. I believe what occurred was there was some carbon deposits collected on the plug threads the were sticking into the burning chamber. Do not use PB Blaster, use carb cleaner or Ford"s very own version PM-3 https://amzn.to/1Hlkh6D as that will soften/loosen the deposits.One side, then the other: I read this tip before I did my plug change. Someone claimed to execute one bank, then begin the engine to do sure every little thing is good before law the other side. I would actually speak don"t perform that as beginning it heats increase the engine, heads, etc. Leaving the engine cold, execute them all, and if over there is a difficulty when you"re done, deal with it then.If you have actually tips I have actually not noted here that would be useful to 2 valve Triton engine owner who space looking to readjust their plugs, please short article below. Ns am by no means the expert on spark plugs however I read a lot of misinformation the end there prior to tackling the plugs on my F-150.p.s. As an aside, the shorty ratchet ns bought is a Snap-On FK80, that worked an excellent back on #4. I find myself making use of it an ext than my much longer ratchets now. Examine it the end
