Everyone is entitled to their own opinion, but I love the +4s. Maybe it has something to do with gas, driving habits, milage, etc. But the Bosch plugs get my vote.

Had Bosch, they work ok but very slowly over time( not a long time when your towin' a 5th wheel)you will notice that your engine will take a little longer to start. The Platium eletrode will burn down inside the ceramic and increase your spark gap and there is no way to fix that, but to chuck them.
I have had Champion Truck Plugs for two years and last week I took a couple out just to see what they looked like. WOW. They almost looked new, no carbon no brown soot and the ceramic was snow white.

I've tried a lot of different plugs over the years (53 in June). But if you have a chrysler/dodge product stick with Champion, that's what they were design to run with.

Spend your money on a set of truck plugs, there tough, they won't let you down when your haulin' *** or a heavy load.

 

so what would yall reccomend me to do. Take the plugs back? i havent put them in yet and if i take them back where do i get the autolite plugs at? Dont really care for champions cuz ive used them in different vehicles and they ran like crap. Thats coming from me, half chevy half dodge guy!! So what do yall think about the autolite wires too. Oh, and how do you gut your cat, mines rattling like a tin can.

 

I'd take those plugs back. I've heard nothing but bad about them. When I used to work at a shop we always had cars coming in with them that were having problems running correctly and we would usually get it fixxed just by chaning those out. When I asked about them at Advance a long time ago the guy told me not to buy them as he has had a lot of people come back saying they make their cars run horribly.

I'd go with Champion plugs personally. Several people on this site and others seem to have good luck with the Autolites so I put a set in mine. Soon after a slight missfire atleast thats what it acted like appeared. I couldn't figure out what it was until I decided to change my plugs back to Champions just to see if it helped. Sure enough right after putting those in it went away and has ran great since. I'd just go with them.


For wires I like my MSD's but Autolites probably arn't bad either. I don't know what to reccomend in the way of wires. I have a set of Taylor Thundervolts on my Honda and they seem good too but I've never run them on the Ram so can't comment on them for this.
