I checked fordparts.com for replacement plugs and came back with AWSF32PP (double platinum i assume) for $8.92. However, i called my local dealer and they gave me a price of $10 on a AGSF32FM plug. So i call Autozone, Advance Auto, and Pep Boys and got a price of $5.09 on SP432's. I'm lost here... which is the proper plug?

 

www.motorcraft.com

 

fordparts.com and motorcraft.com are same site. They list 2 plugs..

SP413: Nickel, $5.68
AWSF32PP: Platinum, $8.92

But when i called the dealer they told me I needed the AGSF32FM's @ $10

 

Use what ever plug you want lol I've ran different kinds with no difference in how long they last and how well they perform you would have to show me proof that one plug is different than another lol just my opinion

 

Just get the motocraft plug so I don't get a 8 page thing on how they are different from a professor that's never put a spark plug in his own vehicle lol

 

Sounds good enough for me. What is ur opinion on the wires? The motor craft wires are $156 while aftermarket sets are $50 to $60. That's a pretty big difference in my wallet.

 

Do what you can afford look at it this way if you spend 50 on wires and your truck runs that's always the route I would take same your money for other mods like tires rims and so on

 

In case anyone was/is shopping for same parts, I found them about half price at www.rockauto.com . Searching thru the forums, I saw alot of people reccomending buying parts from there so i gave it a try. They were right.

8 Motorcraft AGSF32-FM Platinum Plugs (AKA SP432) = $28
1 Set of Motorcraft WR5934 Spark Plug Wires = $61

Plus $8 Shipping comes out to $97. Dealer wanted $240 for the same parts. Thats alot of beer money!
