doing the plugs and wires this weekend. what are the best ones? was going to use topline bosch at autozone. also i have the 5.9 never messed with distributor so should i change cap and rotor? when should i change the distributor the truck has 90000 miles on it? any help would be great...

 

the cheap champions work fine as most will say least on the 5.7 thats the case

 

Cap and rotor should be every 30k miles, so I'd say it should be done, will take you 20 mins topps. Just remember to remove one wire at a time off the old one and place it on the new one in the same location.

Unlike the Hemi, which seems to hate everything but the cheap copper plugs, my '98 5.9 loved Bosch Platinums, dunno if the performance was any better but I picked up about 1.5 mpgs when I switched to them...

 

thanks for the info but what do you think about the distributor? u think that is one of those components that is replace when broke? if i do replace what is a top line one? should i order an msd from summit? any info would be great thanks again...
