What is the correct replacement air filter for 70 model 442 w OAI? All the online lookups say a212cw which is the 14" Dia filter, but that is too big. Looks like it needs to be 13" dia?

 

AC 366c if memory serves me.

 

Ok wow - seems to be out of stock everywhere.

 

Like everything in life, there are usually exceptions:

Of course

 

AC 366c is definitely the correct filter/number for the OAI-equipped car. The filter isn't as thick (cross section thickness) as others and the OAI inner metal lids are stamped to only work with this thinner design.

I have a Wix version of the 366c here and it's PN 42102. If still available the price would likely be A LOT LESS than the AC version (on ebay).

EDIT/ADD: Looks like the Wix version (42102) is available at MANY auto parts stores, internet vendors, etc. O'Reilly's shows it for around $19.

 

Had to order one - what is the world coming to?

 

They haven't been openly available for 20 years

 

The odds of a regular auto parts store selling a 366c are slim to none. Think about how many OAI cars are already restored....those cars will probably NEVER need another air filter. So....who in their "right" mind would keep these on their shelves? Makes perfect business sense to me.

 

Huh? You expect a commercial business to carry a part for a half-century-old car that was rare even when it was new in the hopes that someone might need it, when that warehouse space could be used for inventory that is actually needed today and turns over frequently so they can make a profit?

 

212 must be a fit for all, the parts guy said its for my TA, it isn’t. I got a new one in the box.

 

212 is the generic 14x2 filter used on nearly all GM 4bbl. The 366 was used on the 70-72 O.A.I. cars.

 

A212CW is a 14 x 3, not 2.

And I was trying to be funny with my "what is the world coming to" - Buford T Justice

 

You are correct, thanks for catching that.

 

I caught the Joke, I’m a Pontiac guy 🤣
