running bosch platinum+2's in mine. had a durango a little while back and put them in there and the 5.2 seemed to like them. so i put em in my ram and like em.
dont remember where i saw it now but there is a dyno test with bosch platinums vs autolite copper 3923 and the autolite won out. I have used both and there is a bit faster start to the autolites plus they are cheaper
I just put in bosch platinum plus 2s, only plugs i run in my vehicles. They held up great in my mustang and proved themselves once again in my dodge:box2:
well i had bosch platinum +2's in my truck for 8 months and they started fouling out, so no more bosch for me. i replaced them with e3's. not but a dollar more...plus i had a 5 dollar off coupon.
My Ram is running with the Autolite AP5224 (Single Platinums) and they are side gaped like the higher priced racing plugs. The more spark visible, the better the fuel and air burn. The 3923s are good too, but in some instances, they tend to make the O2 sensor life shorter in the Magnum engines.
All I know is that the Champion plugs cost me a mere $300 to get them pulled out of the block. The original owner never changed them from the show room floor up to 60,000 miles. Those dumb plugs were frozen and three broke. A shop had to EZ-out them and breaking the EZ-out in the process.
I was running a set of Bosch +4's and found that after 30,000 kms that my fuel mileage went goodbye the truck started to stall out after I fired him up first thing in the morning so I pulled those plugs and found out that the electrode was missing in 2 of the plugs went to the local dodge dealer and they said do not run these plugs due to this issue goes for both +2's and +4's ( apparently magnums like to eat them) cause u can send the electrode threw the top of the pistons i lucked out and didnt WOOOHOOO !!! so now im running a set of NGK Platinums takes a little bit more to start up but i have better mileage then when i bought my truck a year ago NGK's OR E3's all the way !
I just put in a set of NGK plugs a couple weeks ago, went ahead and swapped in some MSD 8mm plug wires while I was at it and a new dist. cap, she was runnin good before but now she's runnin great!!
