I'm not finding a place to buy the Autolite double platinum plugs. I've checked Autozone, Pep Boys, Advance Auto Parts, Federated, NAPA and Rock Auto. We do not have O'Riley's in MD... My 2010 V6 will be hiting 100k within next week or two and I want to get tune up stuff ready. Is everyone just EBay/Amazon buying them?



Rock Auto shows people like the DENSO Part # 5326 and NGK Part # 7159 plugs?

OEM plugs preferred. Autolite XP5143 (Double Platinum) or AP5143 (Single) for the Gen 2 V6.

Wires are a personal preference, many aftermarket around the same price as OEM. Search.
 
According to Autolite's web site they are the correct XP Series plug.

Seems the single platinum AP 5143 plugs are available everywhere. :banghead:

 
I would use the Motorcraft SP412 single platinum finewire since the AP5143 isn't nickel plated.

Either choice is good for another 60-100K. Gap @ .054 and buy a counter pack of anti seize. :banana:
