D9AZ 6731 A ARE $9.74 retail each. Ford mtr co has 23 of them in stock.

Good, I am buying 10 from Ford today for myself and anyone else that wants them

And clean oil is better than dirty expensive oil too!

I thought these were no longer available - stuff me!

Hey Uniacidz & Papa,

Can you please advise what is the color of the anti-drainback valve on these filters? I believe the "new" ones are red/orange in color (made of silicone) and not black (Nitrile rubber) as per pictures at the start of this topic. Can you guys please verify???

Thanks...

We will have 10 tomorrow from Melbourne, I will see if they have the Orange insides.

More than likely not.

We got the D9AZ 6731 A in today and they have a black rubber valve where as the AFL 1MC is Orange.
I am using the FL 1A in my AU and have had no issues.

Silicone anti-drain back valves (red/orange in color):
* Help prevent oil from draining out of the filter and engine when the engine is not running
* Resist the aging effects that an engine’s high heat can cause
* Silicone is superior to nitrile rubber (black in color), which can become brittle over time

I am led to believe these "black" ones are an older batch as Motorcraft now produce Silicone anti-drain back valves on all of their filters.

I think you'll find most (if not all) filter manufacturers are going Silicone due to the fact cars are being service every 15,000km / 1 yr. They are finding this black type anti-drain back valve going brittle.

I change my oil every 7,500km (around 6 months) and I believe the black type is still intact.
