So I ordered Motorcraft Spark Plugs for my 2001 SVT Cobra (using my VIN to get correct part) and here is what I got:
Motorcraft SP-433 AGSF32WM Platunum
When I pulled the plugs from the block to change, I noticed the plugs appear identical (overall length, size, gap) but had a much shorter cut thread length overall on the barrel shaft. The old plugs had a different part number too:
Motorcraft AWSF 32E Platunum
The plugs appear identical, but the old threads maybe go up from the bottom 1/2" until a smooth taper and the new ones go up probably a full 1" to the plug taper.
I called Ford thinking I have the wrong plugs. They confirmed the AWSF 32E plugs were the original plugs and part # for this car but were superseded by the AGSF32WM plug. Normal - parts change a lot.
I explained the concern and they checked, double checked, and triple checked that the new part was proper for my car. They transferred me to a 'specialist' and he confirmed the new plug number and said the reason for change is that plug is used in multiple cars now most likely. Since the block is tapered, the plug will go in and stop (which it did I confirmed) and some threads would stick out the top of the block. The important thing was since the block is tapered, the plug will still only go in the exact same amount and everything will be fine.
Anyone else see this, or changed to new Motorcraft plugs recently? These are supposed to be plugs for 99-04 Cobras.
