Confirmed!
just to add to the confirmation i also have the expensive plug in my 08.
Confirmed!
And in the middle of model year too - that'll be fun... Just like the oil level/temp sensor that you have to order with the engine code to get the right one...Wow a old school plug didn't see this coming
Confirmed!
Confirmed where? Source?
Thank You.Here is the spark plug out of an 08 Bullitt. Car was built on 02/08.
The HJFS 24FP is the part number. SP509 is the motorcraft number. $10 each thru my local motorcraft supplier.
So I'm woundering if the new heads will work with the old engines.
Looks like they will. This is going to get really screwy though. 1st, Ford changed the valve covers, now they actually change the heads to allow for the change in the spark plugs. The aftermarket crowd is going to be pissed as well as the consumers. Oh well...
I wish they would have gone with this spark plug from the start!
Ford had to wait for factory warranties to expire.
I wonder if there is any flow diff or did they just tap the head for another plug...
