So, my word isnt enough?
In my 3.7 which is the same motor with 2 cylinders chopped off, I put the 3923's in and it made a HUGE improvement to the idle and throttle response. Also made the truck run much smoother.

RE: spark plugs for the 4.7 motor...
I will try that, thanks.
As far as the cooling lines over the #3 coil, when you take the air hat off you will see 2 plastic clamps that hold the cooling lines together on either side of the engine. Pop them loose and there is enough play in the lines that you can split them apart to get the coil & plug out and back in. I think they affect the #4 coil and plug as well.

thanks for the heads up on the plugs, much appreciated.
the mmo is great stuff, over in the 2nd gen ram forum I posted info on my daughters sucess with it... IIRC she went from mid 20's for mileage to the low 30's. she was quite happy with it. once your motors clean, if you stick with high end oils (mobil 1 minimum IMO) you wont have any issues with crap in the motor.
