Had the dealer do it at 30K. $289 parts and labor.

 

installed the autolite Irdiums last night with 100,000 kms on my truck. Pretty painless, I had installed the OEM plugs at 50,000 kms so I learnt a trick or two from the last time. I also put in a Poweraid throttle body spacer in too while I had my intake off.

 

Throttle body spacer does nothing on a port injected engine except make noise. They work on carbureted and throttle body(injectors IN the t//b) intake systems.

 

Just changed my plugs in my 2009 1500 Laramie at 30,418K miles. Was certainly a challenge, but with an assortment of extensions the job went pretty good. Patience, persistence, and not minding laying across the engine on your belly are requirements for this job. Used the OEM NGK plugs w/o anti seize. Took about 1.5 hours. Got the plugs at local dealer for $72. My ribs are a little sore but worth saving over $200.

 

Should have at least used he factory Platinum's. You'd be 130,000 before doing them again. Maybe next time.

 

$207.15 for plugs

 

Those are a pulse duration plugs. They are the ones causing running and charge system issues. DO NOT USE.

 

Do you have a part number for the factory platinums??

 

No. Dealer parts man does.

 

Appearantly you haven't been to my dealer...
Last time I picked up parts there kid asked me if I wanted fries with that :-/
