So picked up a Fram air filter based on their site. Naturally it does not fit.

The one they listed for a 67 Delta with 425 and 2 barrel (auto trans) is about 2" too small for ID and OD.

Are the K&Ns worth it and if so, can anyone tell me the part number for them?

Thanks

 

Keep in mind that any listing you find today will be for the conventional air cleaner housing, not the climate controlled version. Simply measure the element you have and select a replacement based on size, not catalog listing. If the old element has a number on it, the parts store should be able to cross reference it. I suggest you avoid the K&N filters. They flow more air because they also flow more dirt. Many tests by heavy equipment manufacturers have proven this with accelerated engine wear due to particulates getting past the K&N filter. Just use a good quality paper filter (not Fram, by the way) and replace it regularly.

 

And, I would add, if you can't find a number on the filter you've got (which will almost definitely answer your question), just bring the old filter into the store and hold it up to the air cleaner boxes - air cleaners are almost always packed in boxes that are the same size as the filters - find a few that seem close, then take out the filters and compare them.

I remember that the '61 Mercedes I had years ago ran the same filter as an '81 Chrysler K-car (which was, ahem, a lot cheaper than the one offered by our former enemies...).

Get whatever crosses to an AC A90-CW. The CCC system used the same filter element as the 4-barrel engine.

A90-CW was used 1959-67. It's an obsolete number but I'm told they can still be found.

 

Must be your lucky day.. there is one on ebay ... click here...

 

Cool. The guy lists the GM part # as 6422327 as well

 

I like his "exact application". 67 Toronado is one of many applications this filter is used, and I can't for my life figure out what ATC has to do with an airfilter.

25 bucks might sound like a lot for an airfilter element, but parts store pricing is not far off on most other "modern" filters. Get this one and you know it is the correct filter.

 

The seller is parroting back what he has found on the box or in a parts book, and has no idea. I have seen stranger descriptions in GM parts books, and you sometimes wonder if they might have made a different part for certain color cars, based on the descriptions.

 

Just go to your local NAPA or other parts store and get this: http://www.wixfilters.com/filterlook...asp?Part=42081

NAPA Gold filter number is 2081 (same number as WIX, less the first digit) is $9.49 at my local store.

Or $6.69 from RockAuto.
