1966 3x2 Smog
 

Follow-up on post #9 with the ‘66 Tri-Power with A.I.R.
Engine code WV (1550) produced.

This is a spare unit showing some up close views of this “one year only” complicated system.

The “Special air cleaner” for the air injection pump is unique.

The large plastic cap on the back unscrews to access the filter inside the snorkeled air cleaner.
This filter has a flat piece of perforated metal sandwiched between oiled foam.

Looking inside the air cleaner shows the accumulated dirt on the intake side of where the foam filter would be.

I have another separate air cleaner with the metal plate that has different wording on the cap.

NOS A224C oiled filter in plastic bag.

I purchased this ‘66 3x2’s smog unit about 40 years ago from an older gentleman at a swap meet. He said it had been sitting on the garage shelf for years.

----Thanks for all this great info, Chris! That air injection pump air-cleaner was also used on 67 442's as I had one. The system was incomplete, probably because the 442 migrated to Minnesota where I bought it. The missing pieces were just about impossible to track down.....Bill S
