4.6 engine spark plug question

Hello all,
Was curious to learn what a good cost effective cross-over would be for the OEM Motorcraft AWSF32pp spark plugs?

If you look around on the net, there are deals out there on the OEM plugs.

I am a fan of Motorcraft because they just work.

Also make sure you gap the plugs to the engine specific gap.

Use only Motorcraft, do not use antiseize, and torque them to 28 ft/lb. Aftermarket Motorcraft part number is SP432. $4.99 each retail at O'Reilly, can be found online for less than $4. Try rockauto.com.

Thanks for all the replies. I found SP432 plugs on EBay for $3.75 who excepted a offer of $3.50. Any one interested let me know, I'll pass on the link. It has been a while since the plugs where replaced and need to have my memory refreshed as to where the dielectric grease is applied to a non COP set up?
Thanks again!
