Called my local Dealer here in Ga. $210 includes parts and labor. He suggested to have the throttle body removed and cleaned for $89 plus a full fuel injection cleaning for $99. What everyone's thoughts... one concern I have is should the fuel injection cleaning be done first not to screw up the new plugs?

 

let the dealer do the plugs, you can get some TB cleaner and do it yourself, it's really easy. The FI cleaning is not really needed but if you want to do something, get a bottle of Techron concentrate and put it in the fuel tank when you fill up

 

dont waste your money on tb cleaning etc. imho. my throttle body was clean as a whistle at 40k miles... they are just selling snake oil. especially on a truck which is fairly new

 

Let the dealer install the plugs, but only if you have confidence that they wont crack the insulator(s) on the new plugs installing them. If it starts to skip/misfire, they likely cracked one or two or more of the new plugs. I`ve seen dealerships even break the coil packs/broken connectors. Most dealer monkey`s are just that, monkeys, ram an slam, break ****, and they dont give a rats azz. Always remember, today its all about greed... quanity before quality is the way it is today. Nobody is going to care for your vehicle more than you do.

Before you change the plugs....
Add a full bottle of GUMOUT (high concentrated formula) fuel injection cleaner to a full tank of gas.
Run the tank down to almost empty. Then go change the plugs.

Dealer wants to remove the throttle body to clean it...??? No, absolutely not...!
You can do this yourself before the plug change... one spray can of GUMOUT carb/fuel injection cleaner.
Pull the air intake tube off, spray entire inside, done. I`ve found that most dont need it though.
If you install a oil trap can within the PCV and the TB, that stops alot of oil being sucked down the intake.
Also a GOOD quality air filter keeps the TB & intake track clean as well.

 

Part number for the NGK's that we should be using on our 09 Hemi Ram's??
I see the Autolite part number but not the NGK part number on this thread. Went online and there are 2 options. One of which is a Laser platinum (PLZFR5B13EG) and the other is Standard (LZFR5C-11)

Not sure which one is needed/better or meant to compare to stock. Thanks guys!

 

XP5325 is the Autolite Iridium plug for the 5.7 Hemi. I don't know the cop car or hybred 5.7 Hemi Ngk Platiumn plug number. They are 100k plugs. Well worth getting so no more 16 plugs every 30k. Some makes the TB gets nasty some don't. Don' know about Hemis. I looked in mine with a flashlight at 30k and it was spotless. My vettes 6.2 was somewhat nasty. I pulled it and cleaned it.

 

hey, Ya'll got me skeered bout doin my plugs....wait 16 of "em!!? uh... what was or should have been the factory original plugs... cuz thats whats about to come out of my 05 durango hemi ... and i certainly will be using the same thing since i got 200k from the originals!! autolite? ngk? champion? platinum? iridium? copper? Thanks yo... J.R.

 

Factory are ngk copper

 

Different years and different applications used different plugs. My son's 2003 hemi and a friends 2007 use different numbers. The plugs that I removed from my 2010 Ram 5.7, and listed by Chrysler in the service literature, were NGK SPLZFR5C11. The odd thing was neither of the two auto parts stores I went to that carried NGK spark plugs listed that number. I ended up buying NGKs from my dealer for $3.15 a piece.

Use a 100,000 mile plug. The NGK Platinum for the 5.7 Hy-bred or Cop car. Its taking a while before release to aftermarket on the factory plug. It will happen eventually. I'm using Autolite XP5325s Iridium. 5 year unlimited mileage guarantee. Bought through Amazon.com with a $2.00 per plug rebate through Autolite. I've had them 8000 miiles. Bit smoother idle and maybe a hair better fuel mpg. To heck with changing 16 plugs every 30,000.
