Does anyone know the part number for the Champion Truck Plugs for the 5.9? Different places are giving me different numbers. Im getting 4071 and several others. Also thinking of just going with the Autolites. Thanks

 

4071 is the # for the STOCK heat range plug for the Champion Truck Plugs.

Autolite is 3924

 

I like the autolite 3923's. They got rid of the ping that developed going up hills after I installed my hypertech program. Plus, they were only $1.29 each, can't beat that price.
