yes, they will fit all rams 3.9, 5.2 & 5.9 motors

 

i got autolite plugs from autozone.. but im not sure if their the 3923 ones.. all i know is that their autolites.. is there a big diffrence if i didnt have the 3923's?

 

there are the 3924's which would be a stock equiv. plug. the 3923's are 1 step colder to help against pinging. there has been a 5 hp gain dyno verified on some motors so it is what's recommended.

 

oh i see.. are they the coldest plugs?? is that why its recommended?? also.. i'd recommend getting new gears in the rig to help with gas mileage and power.. i race my friends 02 ram 1500 with the 4.7l v8 (new body style).. had him threw 1st and 2nd but he got me in 3rd.. pretty much because i have a 5 speed manual and he has a 4 speed auto. but im thinking putting 4.10's in my truck would help me keep up with him since i have the stock 3.55's on 33's

 

no they're not the coldest, just 1 step colder than stock. you do need the 4.11's because of the 33's on there, it'll run alot better.

 

sounds good.. whats a good website for new gears?? how much do they usually go for???
