Thank you! What does NGK recommend for torque? Also, those part numbers you listed, please search for me and tell me what they are for PZEV vehicles and non "California" emission vehicles. Thank you!

For both I4 and V6 - NGK website recommends the following torque spec:

Cast Iron: 10.8-18 lb. ft. Aluminum: 10.8-14.5 lb. ft. This engine is a pressure-cast aluminum head.

Rick, couldn't immediately find the PZEV spark plugs needed. Will post back if I do.

The following website lists the powertrain specs (this is for 2013 not 2014, but I would assume both years are the same):

Thanks @Accordnajkr for sharing this. Good to know how easy it'll be when the time comes to do this service.

Coincidentally, I'm doing this for my G35 and it is a pain in the @$$ getting to the ignition coils.

Why would anyone ignore Honda’s recommend procedure, and instead follow a parts supplier’s recommendation; especially when it comes to torque values to be used on a critical component like Honda cylinder heads. Do you have any reason to believe Honda’s recommended spark plug torque or installation procedure is incorrect?

Did you read NGK's explanation of why?
I didn't think so.

 

[lebowski]

Did you read NGK's explanation of why?
I didn't think so.

Not only did I read it, I’m positive I better understand what they are saying between the lines and that appears to have eluded your own understanding.

Are you of the opinion that NGK knows more about Honda’s cylinder heads than Honda? Seems like a very difficult position to defend.

But while I’m here, and you’re devising your defense of NGK over Honda, I’ll paraphrase NGKs position for you:

“Poorly trained and lazy people who change spark plugs can’t be trusted to read the required torque specifications, much less use an actual torque wrench. We’ve designed an ablative coating that will protect most of these idiots from their own incompetence (nothing is 100% idiot proof) that we think works pretty well. Now if you remove one of our fancy plugs, and wish you reinstall it, you will need to use anti seize compound because the ablative coating will have destroyed itself during removal. At this point, and if you are the idiot we think you might be, it’s probably best to seek competent help.”

Now in contrast here’s Honda’s position:

“Use a bit of anti seize compound on spark plug threads and torque the plugs to the specified value. What is not explicitly stated, but what is implicitly understood, is that you are able to follow instructions, have a torque wrench, and know how to use it.”

What is left is for you to decide which target audience you belong to, and to act accordingly.

Anyway, since we’re discussing spark plugs, one often overlooked but critical function of spark plugs is the removal of heat from the combustion chamber. An under tightened plug may not be able to transfer heat as effectively as it’s required to, which can lead to overheating of the plug tip, pre-ignition, and engine damage. I have personally experienced this phenomenon (minus the engine damage because I recognized the problem) which was cured by torquing the plug to the engine manufacturers specification, which was materially higher than the plug manufacturers recommendation.

In summary, you want to get your spark plugs torque correct, and the plug manufacturers one size fits all recommendation might not be what’s best for your particular engine. Logic tells me that the engineers that designed, and the factory that built, your engine, probably know what plug type and torque is best.

 

[WABOOM]

All of what you said is true, but NGK definitely knows what they are doing with spark plugs in Jap engines. More so than any other brand on the planet IMO. Combustion, heat transfer, ignition etc are their specialty.
At the end of the day we all do what we we believe and usually what makes us feel the best.

Your view of "Honda's position" is exactly why NGK states not to use anti seize on their spark plugs regardless of engine.

From NGK's website "Anti-seize compound can act as a lubricant altering torque values up to 20 percent, increasing the risk of spark plug thread breakage."

Even if you're following the instructions you will not account for the anti seize acting as a lubricant altering the torque up to 20%.

I have nearly 200k kms on my car with spark plugs that have been changed at 160k km. The spark plugs went in dry.

Do you think that Honda doesn’t fully understand the lubricant properties of anti seize and therefore didn’t take that into account with their specifications? Does it make sense to you that the lubricant properties of anti seize was just recently discovered by NGK, and that their specifications now supersede what Honda still writes in their factory service manuals today? Could it be that Honda engineers can’t grasp what you’ve embraced about spark plug torque, and that your knowledge is far superior to theirs?

Or is is most probable that Honda engineers fully understand the workings of the engines they designed, that they know of and fully account for the properties of the anti seize they recommend, and that their torque values reflect their decades of experience building millions of some of the worlds most sophisticated engines and are completely correct and appropriate.

Doesn’t it make sense that when Joe four pack doesn’t use a torque wrench, and over tightens the plugs because that’s what feels right, he’s more likely to damage a plug that’s lubricated with anti seize than one that’s not. Isn’t it logical that NGK would look for a solution to protect Joe, not from the correct factory recommendations and torque specifications, but from his own laziness, incompetence, and ineptitude?

Here’s the question I would like you to answer if you can: Why does NGK advise you to use anti seize on coated plugs that have been removed, and on their uncoated plugs, and how come what was formally specifically recommended against is now suddenly fine, and in fact necessary and recommended?

From the NGK link above:

“Torque is critical in the plug’s ability to dissipate heat and perform properly. Always follow the manufacturer’s recommended torque specification. An under-torqued spark plug can lead to excessive vibration and improper heat dissipation, causing spark plug and/or engine damage.”

Honda’s torque specification assumes the use of anti seize. If you use the average of NGKs torque range (~12.5 lb-ft) you’re only torquing your plug to roughly 65% of Honda’s specified value if you assume the recommendation anti seize increases effective torque by 20%.

You are quoting from a post you think is from Honda. No such citation stating this is from Honda.

There are several possible sources of the images and information provided by the OP in the opening post. In decreasing probability they are Honda or a publisher authorized by Honda to develop and distribute a factory service manual, primarily for the use of Honda dealer or other authorized technicians that from time to time will be required to work on our Accords.

Alternatively, it is some random publisher that has developed an independent service manual at great expense, and without the assistance or authorization of Honda, that has drawn hundreds of exceptionally well rendered illustrations (also extraordinarily costly), that has independently developed hundreds of procedures for frequently complex maintenance and repairs, all in the hopes that Honda technicians will purchase their unauthorized and likely unreliable publication (heck, they can’t even get spark plugs right) and risk their reputation and career on the outcome.

Which of the two possibilities do you think the more likely, Rick?

Better yet, do you know of an alternative Honda authorized and approved source of technical information and service and maintenance procedures, and if so, what does it say about the use of anti seize on spark plugs and the appropriate plug torque for our generation engines?

If you do, wonderful!, and please share. If you don’t, you have nothing other than a one size fits all recommendation from a company that states clearly to, “Always follow the manufacturer’s torque recommendation”, which in this case, if you choose the more probable path, directly contradicts the plug makers approach.

On a separate issue, I find it both odd and frustrating that in 2019, with the worlds information at our fingertips, we can’t be fully confident in even the most basic information for our Accords, one of the most popular cars on the road today. Despite our collective resources this is even so on what is probably the most popular forum for all generations of Honda’s. How is it even possible that six years after our generation model came out we still don’t know how to install or torque a spark plug in our engine with any real degree of certainty?

Of what value is any of this if all we are engaging in is idle speculation?
