Re: Hemi spark plug change interval?
I just changed my plugs with NGK OEM plugs @ 47,000 taking 1.5 hours from start to finish
The plugs removed looked excellent with the gap @ .044. My mileage was still 17 city/highway and 20-21 highway.
As others have noted on this form the procedure was relatively simple and I would recommend not spending $$$ to have a dealer do so.
Based upon my experience I will wait for another 60,000 before replacing the plugs,
