The only difference IIRC is the 2500 doesn't have VVT and MDS(honestly not exactly sure what things it does or doesn't have), so the plugs should be the same. Point is no matter if it has or doesn't have VVT or MDS, this has no effect on the plugs, the engine itself is physically the same.

I think I'll give 'em a try. Just hope there are no warranty issues.

Question

Just about to change my plugs...

Wondering if there has been any update on the MOPAR POLICE PLUGS - or the aforementioned DENSO plugs?

You guys still loving 'em?

TIA

I'm still very happy with the Mopar Police Plugs, no issues what so ever...... Hope they last the full 100k miles as advertised

Question

And they have arrived...



Debating on installing them myself or having my mechanic do it for $100. After hearing all the complaints about installing them, its tempting to let someone else do it.

Can someone confirm the GAP (.043) and torque?

Thanks

I'm not sure what the gap is supposed to be on the hemi but if you try to gap them with a typical gap tool you will damage the iridium electrode. You may damage just by checking the gap depending on what tool you are using. You should use a feeler gauge, not that hard disc that the auto parts stores always have at the counter.

Found an informative YouTube video from NGK on the proper way to gap iridium plugs.

Arrow

TO further clarify the gap question, I sent a message to the NGK folks from their website. Here was NGK's response:
Quote:
Hello,

These plugs should come out pre-gapped to 0.044", this is indicated by the -11 at the end of the part number which would be 1.1mm or 0.044".

My Owners Manual specifies .043, so I replied asking them to clarify - should the plugs be set to the engine spec or stay at the plug spec?
It is a minor difference... So there you have the rest of the story... We'll see what their response is.

____________________________________

WOW got a quick response:

Quote:
Hello,

The correct torque spec would be 17-21 ft lbs. and this plug will come out at 0.044 we were the OEM provider for this application and show that 0.044 is that the OEM gap is. However 0.001 will not make a difference.
