Thanks glc. Installed last night. They are wonderful on test drive. Will be putting 50 mi on them today. I'll post any problems if they arise.

They arrived lickedy split too!

 

Are they any good?

 

Supposedly every bit as good as Motorcraft.

Rock Auto's prices on the DG511's are $34.89 compared to Motorcraft at $45.79. The DG508's are $31.79 and $41.79. A set of 8 at just over 100 bucks from this Ebay store is a great deal.

 

Just put 25 miles on them on the way to work. Flawless. No codes. New OEM plus and the Delphi's got me to 17.5 MPG when I normally see 14.7 to 16 on average. (Not instant read MPG.)

Local retailers wanted 400 or so for Motorcraft and about 500 for Delphi.

 

Looks like they are now out of stock on both sets.

 

It was almost 28 bucks when I posted the 3V link. About the same price as Wal Mart.
