JanZverina Posted January 3, 2023 Share Posted January 3, 2023 Happy New Year! I'm looking for an air filter element for my '63 Riv with a 401. Wix lists the p/n as 42092 (different from the one for the 425, which is 42082). CARS Inc. lists them as AF636 for the 401 and AF646 for the 425. I want to make sure I get the right one, which has a lipped edge on the one side and which I think is flatter. Any leads/guidance appreciated!

RivNut Posted January 3, 2023 Share Posted January 3, 2023 (edited) As far as the CARS part numbers are concerned, the 636 number applies to the 63/64 single four barrel engine. The 646 applies to the 64/65 dual four barrel engine. Edited January 3, 2023 by RivNut (see edit history) Link to comment Share on other sites More sharing options...
JanZverina Posted January 3, 2023 Author Share Posted January 3, 2023 Thanks, Ed. Am I right in thinking that the one for the 401 is a "flatter" shape? I prefer Wix filters but understand that various components will go out of production after many years or be picked up by specialists. Link to comment Share on other sites More sharing options...

RivNut Posted January 4, 2023 Share Posted January 4, 2023 I'm not familiar with the different dimensions. It's ben a while since i bought either one. On their own website, Wix does not show any 1st generation Riviera air filters. The Wix part number is 42092. When I Googled that part number I was directed to Summit. They show out of stock but should be on hand in late February. No more than these cars are driven, I think the one from CARS would be fine. Around town when my 63 was my daily driver, I used an open element with an after market housing. Link to comment Share on other sites More sharing options...

I’ve been an Amazon customer seems like forever. This is the first instance I’ve seen of a delayed notice for delivery. They either ship or tell you it’s not in stock. Just relating my experiences with Amazon. I hope you get it and let the rest of us know so that we too can purchase what we need. Ed Link to comment Share on other sites More sharing options...
JanZverina Posted January 4, 2023 Author Share Posted January 4, 2023 Thanks for the info, everyone. Via AMZ, they're telling me 2-3 weeks. Re onlinefiltersupply, shipping is more than the cost of the filter but either way the Wix 42-92 looks to be available but we'll see, as Ed says. Thanks again for the responses. -JZ Link to comment Share on other sites More sharing options...

I know car collectors typically through nickels around like they are man hole covers so the price has to be right. 1 Link to comment Share on other sites More sharing options...
Limolarry Posted January 7 Share Posted January 7 Any updates on the 42092 Wix Filter? Are they available yet? Link to comment Share on other sites More sharing options...
RivNut Posted January 7 Share Posted January 7 I’ll preface that with a never. I’ve talked with James at Bestoffercounts and Steve with CARS. WIX. was the last manufacturer. They’ve bee purchased by a large German company. That company has no intention of producing anything that won’t put at least one of each of there products on the shelf every store in a chain. Just think how many NAPA, AutoZone, O’Reilly, and Advance Auto stores there are; way more than the number of stock 63 & 64 Rivieras out there. In other words “It ain’t gonna happen.” Best thing to do is put an aftermarket unit on your car, clean the old stock one you have to the best of your ability, and save it for the next show & shine. It won’t be part of your driver any longer. 1 Link to comment Share on other sites More sharing options...
BulldogDriver Posted January 7 Share Posted January 7 What Ed said! I’ve also researched the living crap out of this air filter. It ain’t going to happen guys. I personally feel the 3” aftermarket filter is the solution, though not the one I’d hope for but it sure beats having no solution. I’ve had an order in to several suppliers for almost 2 years now. It’s now become an amusement to get the “We can’t fulfill your order” email every couple months. It reminds me of how fragile the supply chain of parts for our cars truly is. If it wasn’t for guys like Gene, James, and the other that make the commitment to the hobby I can’t imagine what it be like out there. No that’s not true, I did have a ‘36 Cadillac before I woke up and let its next caretaker have it. Ray Link to comment Share on other sites More sharing options...

Are you thinking something like a K&N filter? Link to comment Share on other sites More sharing options...

OK, I thought that you guys found an air filter for another vehicle that was round and roughly the correct diameter and height, but it was missing the rubber flange around the top, so you had to make your own flange and stick it on. Am I remembering that wrong? That's the air filter make and number I was trying to get from you guys. I understand that the exact correct original style air filter is no longer available.

RivNut Posted January 9 Share Posted January 9 Jim Cannon and I have been messaging each other about this filter situation. He gave me a NAPA number thinking it was about the same size as the filter I linked from Amazon. I called my local NAPA jobber and asked about ordering one. He looked it up and said that his computer suffixed the number I gave him with an S meaning special order from the manufacturer. In order to even check it out, I would have to pay the $50 price of the item plus $10 - $12 shipping - non of it refundable if didn’t fit. But, he said that his computer showed there were 10 in stock in the NAPA distribution center in Miami, FL. He went on to say that perhaps someone in Miami might be able to get a local store to request one without prepaying or paying shipping charges. If there is someone in Miami who would do this or wants to pay upfront on a hope and a prayer. The NAPA part # is 46974R. NAPA Online shows this as the correct filter for a 1963-1964 Buick Riviera. He said that his reference said it was a WIX filter. What are the chances that there are 10 WIX filters remaining in the Miami warehouse? Someone check this out and let the rest of us know. Hopefully you all realize that the lip on the OE filters just covers the gap between the lid and the base. Running a 16” x 3” filter that does not close the gap filters all the air that enters the carburetor; no unfiltered air gets to the engine. For your weekend drives, use a 16” x 3” filter, then put your old filter in for a show ‘n shine while the car sits. Take it out, drop in the new 16” x 3” filter and drive home. 😄 1 2 Link to comment Share on other sites More sharing options...

The Red FRAM Element I have now is 35 years old but fairly clean still. Careful tapping it against a 6X6 wood fence post. Tapping too aggressively starts to de-form the mesh! It would be too much to ask for a RED element as in my FRAM which I'll never throw-out because it goes with the RED pancake air cleaner better than BLACK! 1 Link to comment Share on other sites More sharing options...
Jim Cannon Posted January 10 Share Posted January 10 I have one of those Fram filters, too, new in the original box. I have never used it because I thought the black rubber flange ring looked better with the red filter housing. The Fram rubber flange looks orange to me. 2 Link to comment Share on other sites More sharing options...
Jim Cannon Posted January 10 Share Posted January 10 Ed, that NAPA filter number is indeed a WIX number. That's where I first found it, on the WIX website. They say it is a Racing Filter. O'Reilley also has it in their online system as Special Order. Rockauto does not. I have 2 NOS filters here, a lifetime supply, so I am not going to order one. I was just trying to get people the information that could help them. 1 1 Link to comment Share on other sites More sharing options...
BulldogDriver Posted January 10 Share Posted January 10 I am almost 2 years into trying to get a couple of these filters. WIX was the last manufacturer of these filters that I can deduce. No one that I have contacted, more than I can remember, have these in stock. With all of the auto order bots that everyone uses today, you aren't going to get a real time response on these filters. They'll take the order then cancel it when their supplier gets back to them with “no gratis”. Fortunately I do have a spare one, but wanted to get a couple more. I see a 16”x3” being ordered in the near future. I’m going to drive the wheels off by car. Was the plan when I bought it and still is.

RivNut Posted January 10 Share Posted January 10 I just talked to the counter guy at the local O’Reilly parts store. I called and told him what I found on their website and would like to order one. He looked it up and said it’s a special order. Me: From your warehouse? Him: No, from the manufacturer. Me: That’s typical. It’s not going to happen unless some discovers a cache of NOS ones on the top shelf, behind an old desk, which is covered with a tarp, and stacked with old personnel files, which are history because everything is now computerized.

Wait a minute, guys... Don't cross up the WIX number that matches the NOS filter, with the flange on top with the WIX number for the basic 16x3 racing filter. I am sure you are not going to get the original style filter any more. But I do think you will find the basic 16x3 racing filter 46974R, because it's less specialized.

RivNut Posted January 10 Share Posted January 10 (edited) Jim, et al The number that you gave to me earlier, 46974R, is the number I asked the counter man at O’Reilly’s to order for me. I covered this in my post of two hours ago. I looked up the part number on the O’Reilly’s website. When it came up, it noted that it fit my 1964 Buick Riviera, which I have noted as “my vehicle” on their site. I saw no reference to it as a racing filter.

XframeFX Posted January 11 Share Posted January 11 (edited) 23 hours ago, RivNut said: It’s not going to happen unless some discovers a cache of NOS ones on the top shelf, behind an old desk Which is the case with Legacy Bosch platinum sparkplug: WR9FP and supplied under at least 3 stock numbers for being pre-gapped to various specs. 4226 comes to mind. They are long discontinued but show-up occasionally as "Clearout" - LOL. Just have to be sharp to catch it with lots of screen time. Time you'll never get back! So, this Forum, good to share your time to help others! Our Low MPG Nailheads will return even worse values with high differential filter elements. A good Post here which heralds the end of this part but has us collaborating together. Unfortunately, no Cigar. As for the air cleaner element, not likely to be like that Bosch sparkplug. Too small an application. I had hoped K&N would've stepped-up to the plate as their claim to fame were CUSTOM FILTER CHARGER Elements. Sure wish I purchased a spare before the window closed.
