Spark Plugs

[k98dave]

Are the AWSF32C plugs still available or has that p/n been changed?

[Meotchh]

There are two available through RockAuto at $.83/ea. Also several on ebay: http://www.ebay.com/itm/like/181291310244?lpid=82

The listings are all for AGSF, whats the difference from AWSF?

[Meotchh]

Ooops. I copied the wrong link there.

As for the difference between the AWSF & the AGSF, I don't know.

from what I remember one is a partial threaded and the other is a full threaded part. in our cars it doesn't matter which one is used since the plug stops against the head. That is.... if I remember correctly. I would have to look it up when I get home. I know I have both on the shelf when I was hoarding parts before we closed our doors..

These all have tapered seats but I recall the short thread plugs had a blow out issue on the 4.6 motors alum heads. Even though we have iron heads I would think the longer thread reach is better.


Just found this

So if Im reading it correctly (did it twice) AWSFA32C translates to:
A-14mm
W-thread reach .708
SFA combined = Conical seat, suppressor, extra wide gnd electrode
32-Cold, extended tip
C- Copper center electrode

The AGSF32C numbered plugs lack the extra wide gnd electrode. Not sure if that's turbo unique or not.
