Spark Plugs for an '09 4.7 liter?
 
I am due to change the upper bank of spark plugs in my '09 Ram with the 4.7 liter. I have checked out the local auto parts stores and dont really trust them. Something is up with selection, they seem to list hundreds of spark plugs for my engine and I know that isn't right.

So, What kind of spark plugs do you guy run? Or what kind have you put in your 4.7? My local dealer says he only has 7 in stock but will order more in. Said he didn't realize they were that low.

You can use either the Bosch FR8TE2 or the FR8T1332 which is what's used in the bottom row.

Would the FR8T1332 be an upgrade? Would I gain anything by using them? Or is it just easier to keep them all the same?

The bottom row plugs are iridium. They went that route because they're a bitch to change. If you want to use iridium up top, these are the ones to go with.

Can you only get them at the dealership?

I wouldn't think so but I haven't searched the parts stores for them.

(I know its old) Just adding this in case someone wanted to get these plugs from another source.

Intake (upper) = Bosch Super Plus (this is the correct Nickel Yttrium plug) FR8LCX( stock # 7962 )

Exhaust (lower) = Bosch PlatinumIR Fusion (this is the correct Iridium plug) FGR8LQI0 ( stock # 4508 )
