I bought my 4x4 2012 ram 4 door new in 2012 and have loved it ever since. 85,000 miles on it and not so much as a door ding (knock wood). I'm gonna do my own spark plug changeout this time around and wondered what is best to go with. Also, there's no miss and it runs great. However, I was told by the dealer when I bought it that the plugs would slowly die without my noticing it and fuel mileage would dip. The set I'm running now has about 50k on them and it seems to be going through gas quicker.
I did my plugs in my 5.7 Challenger a few years ago and ordered Mopar plugs. My recollection is that the Mopar plugs are NGK. The Challenger is fairly easy to get at the plugs, though changing 16 is a pain.
Isn't the 5.7 recessed in the Ram due to the cab forward design? If so the rear plugs will be a pain to get at.
I recently bought a new 6.4 2500 and dread the day the plugs need replaced, looks like a nightmare to get at the back ones. I think I'll pay to have it done! But that's a long way off....
Btw I recently heard somewhere that NGK has anti seize built into the threads, I used a lot when I changed my Challenger's and probably shouldn't have!
I'd certainly try it myself before paying that quoted price!
The 2500 is so tall that even though I'm over 6' tall, I'd need a stepladder to work under the hood.
I think it's plugs are rated for 100K miles and I have 800 on it so far, so it's a long way from plugs...
My trusty 2014 Dart just passed 100K miles recently and I bought some NGKs from Rock Auto for its first plug change. I should get off my butt and do it, 4 plugs and right out in the open so no excuses accepted!
Great to hear you're liking your ram, I have a 2012 Ram hemi crew cab that I plan on milking the plugs untill it has has real issues. Mileage has more to do with my lead foot than anything. Kinda sounds like the dealer wants to change your plugs early, I'd follow the service interval and milk it from there, I've heard ppl getting 150k out of plugs untill they have misfires or noticeable issues. I also plan on holding out to do the exhaust manifold studs....
got an 03 ram with 5.7 and let plugs go till 65k miles. Service manual recommends 35k. I recommend you pull coils and wires and spray rust blaster down the holes and let it sit a few hours. while your waiting pull the driver side tire and remove the plastic inner fender so you can access the rear plugs. You will need an assortment of socket extensions and swivels and patience.
