little help at the end from our messageboard
In this tutorial, Im going
to try and show you how to correctly identify an original 1970 BOSS 302 air cleaner
snorkel with Ford engineering number D0ZF-9A626-B. Hopefully this will help the person
just starting out in the hobby or some that are already in the hobby and want to reference
the correct parts. As to common belief, the 1970 BOSS 302 snorkel is not unique to the
Mustang and Cougar. The 1970 429 SCJ Torino also sported the Ford engineering D0ZF-9A626-B
snorkel. The snorkel I will use for this tutorial is off a Dearborn BOSS 302. This snorkel
is an early take off part with original paint and is a good candidate to reference from as
it has never been modified and is the way it left the factory.
Note paint runs give the
appearance this part was dipped. Details like this are usually lost during restoration.

Following two photos are from John
Slack. One final detail that many fakes get wrong is the flange that attaches the BOSS 302
snorkel has a 90 degree edge all of the way around the opening that bolts against the air
cleaner body. Snorkels from other Fords have a small step on the face that bolts to the
air cleaner body. This is about 1/2 inch wide or so and is actually at the bottom of a
regular Ford snorkel and is an assembly indexer. When a regular snorkel flange is cut down
this step is evident.
