Spark plug Change - What is needed for intake gaskets? (3.6)

[andrei]

Would you pay double the price for spark plugs painted red? There’s no performance benefit from using NGK over champion. The champion plug is the plug that all engine testing would be done with. It is the correct plug.

Any plug that runs it correctly, is a correct plug.
I don't see anyone claiming any benefits over the other. I don't see any talks about performance either. Take a break from internet, your PCM is overheating.
His justification is above and beyond the typical quoting of what is written on the package, or every other retard on here claiming that OEM is the way and only way.

You have said plenty and proven everything there is to prove. No need to continue.

There is no end to talks about Jeep leet engineers and their high rigorous designing and test criteria around here, just as there is no end to some of the dumbest and never ending design flaws that keep putting wranglers out of service... two simply dont go together, enough of this nonsense.

I found the OEM Champion plugs at NAPA for about $7 ea.

Not that it matters, but to throw some kindling in the fire, spark plug threads are very unlikely to be "cut". They are more than likely to be thread rolled. But, stranger things have happened.

On both of my JL’s I’ve owned, I trusted my and the automotive community’s consensus on quality(especially material quality), not necessarily performance. The 2.0 comes with Mopar rebranded NGK’s. The 3.6, the often found in lawn mower’s only Champion Spark plug. The plug where I and those I associated with or even the hot rod/engine builder mags I followed even into the online days thought of where you actually see Champion plugs used. I was genuinely surprised to see this was the OEM plug, much less see it hit almost 100k miles no issues.

It’s just my preference to run NGK. 30 years in the dozens of vehicles I’ve owned with no issues. 5k miles so far with them and the 3.6 runs perfectly. That said, the Champions would have likely been just fine.

Referencing, the spark Plug debate:

I just keep it simple in life, and use only MOPAR OEM original parts, when replacing mine. The factory felt comfortable with them, so do I. But everybody to their own!

Did anyone get mopar part numbers for the green gasket set? I'm going with Denso plugs and new coils, Denso has never failed on my Honda v6 with agressive driving and have proper gap set at factory, out of the box.

I'm old and have seen the introduction of NGK and other previously primarily foreign marketed spark plugs rise in popularity in the US. But that shouldn't diminish the expectation of quality and technology from legacy brands like Champion, AC, Autolite, etc. Afterall, they pioneered most of the tech in spark plugs used today. Of particular note to me, Champion was basically the only or automatic choice for my airplanes. They have been making platinum plugs since at least WW2. My guess is NGK has a similar history in Japan. Champion continues to dominate the aircraft spark plug market and also is a major supplier of turbine engine ignition components.

Nothing inherently wrong with NGK or other brands; but make sure if use a non OEM plug the specs match OEM specs exactly. Differences in heat range and resistance can screw up modern vehicle electronic systems, such as ignition timing, knock sensing, etc….

I got a good deal on a used Harley a few year back because “wasn’t running well after recent tune up”. Put stock Harley plugs back in, ran well.

You might as well stuff a few hundred dollar bills under the intake while you're at it, if you feel like wasting money.

Right? I know engines... nothing lasts forever. 100k on odo and 5k+ RPM use daily, WTF know it all! Gaskets determinate, plugs and coils get weak. No brainer.

Dont be ignorant/arrogant dumb ass, always check for proper gap, ALWAYS, regardless if they claim it was pregaped from factory or not.

 

[roaniecowpony]

... and have proper gap set at factory, out of the box.

Maybe it's just me, but I've found that plugs specified for a particular application from all major brands, come pre-gapped to the proper gap. Shipping damage being the exception. I haven't had to bend an electrode in decades.

Yep, no need in replacing a coil unless its failed. I have 285K on my Civic, original coils. 145K on my Odyssey original coils. I've never replaced a coil on any of my vehicles.

I have not changed mine out yet (waiting for Mopar Dielectric grease to come in), I ordered and got:

68217514AB, Plenum Seal, QTY=6
68232614AA, Intake Manifold Gasket, QTY=6

Based on what? OEM is champion. The plugs the engine is designed for.

Make sure you never change the brand/model/size and air pressure in your tires. Those are the tires that your Jeep is designed for.

Are you familiar with the term “false equivalency”?

Feel free to pay more for the exact same performance from a different spark plug. Comparing plugs to tires is absurd. Do better.
