Always go with NGK spark plugs and leads on the fords. That or genuine Ford. I've found that with other brands you get misfires.
Oh yeah never ever use any engine oil filter besides Ford/Motorcraft either. Other brands have plastic overpressure valves and retainers. Motorcraft have metal ones.
Part No is:
Motorcraft AFL 1 MC
You can get them on ebay for as little as $10 + $7 P&H. I ended up buying 4x ages ago and have 3 left.

And never ever use 10w50. 10w40 would be common choice. Don't get ones with Zinc, Cars with cats are poisoned by zinc.
I'm going to try out 10w30 and see how that goes in mine. It should be fine.
