Interesting that Fram lists the short filter for MY2000 pickups. WIX lists the 51522 (which sounds familiar) that is 4 1/2" tall. I'm positive that initially I was using a tall AC filter on that truck that was replaced w/ the PF48. Starts when I switched to WIX to use a filter similar to the...

For die design 1.5X thread dia' for thread engagement was the standard in GM stamping plants. Going by that standard all of the filters are suspect. ;) 28 years as a tool & die maker in Oshawa, about half of it in the original Truck Plant.

I seem to recall my 2000 Silverado 2500HD w/ the 6 L, used a longer filter then GM obsoleted about 4 filters & started using the a short filter (the PF63?) which resembled a baby food jar. I think if you go to an aftermarket oil filter 'look up' you can see what they spec for the 6 L motors. My...

I am aware of the 'blue' Carquest filters. Not sure what the upcharge is from the 'red' ones is, but knowing the area I'm sure people would 'kick' @ the added cost. the get a daily delivery from the nearest store, so I'm sure they'd use them if a customer requested them. I was showing the...

In light of the latest revision of the PF63, 1999 version: 2023 version: 2024 version: I thought I'd start a thread where the various aftermarket equivalents can be posted. On my 2017 Silverado 2500HD w/ a 6 L, I had been using a WIX 57045 . Now that I have a 2024 w/ the 6.6 L gasser, it...

I remember a segment on Canadian TV back in the 80s. They had several counterfeited auto parts. Showed one oil filter & the element was basically a roll of TP in a can...

I'm sure I've seen that in the past.

Purchased last week at an O'Reilly store in NH last week: This was the 2nd filter I checked. The 1st was made in Mexico.

I just purchased a 2024 Silverado 2500HD w/ the 6.6 L gasser motor. The owner's manual lists the ACDelco PF63 or a GM12707246 filter. Is this another new version?

I checked the link about the air filter test (it included the Duramax filter and the results seemed to mirror the results that Hot Rod or Car Craft magazine did back in the 1980s. Their comparison test on was using an open element air cleaner assy that would be used on the street. Among the...

I have found the second filter mentioned here thru searching (its used on the 6.6 Dmax equippped pickups) but nothing on the first. The two filters are listed on the GM Parts page as fitting my 2017 2500HD gasser. Now looking at the owners manual it lists a A3181C 'Professional' filter (as per...

Thanx!

The same thing has been said about the overseas built 'hobbyist machine tools' (lathes, milling machines and bandsaws). Taiwanese products while not the same as the originals they have cloned, they are superior to the clones from China in build quality.

After I posted earlier in May I was down to Cleveland OH & stopped @ a O'Reillys to pick up 4 various filters that my nephew & I use. I was able to get all 4 US made WIX filters. However for 2 of the styles, the initial filter for 1 was made in China, while on the other, the initial filter was...

I went to the dealer to get a new air filter for my 86 Monte Carlo SS (I've had it since new). I had a NAPA filter on it, but realized what they sold me was too tall (lid wouldn't seal). When I gave the dealer parts person the AC PN, they had to look using the vehicle info. They came up w/ GM PN...

Seeing as the current oil that I have been using on my Polaris Ranger 500 EFI (NAPA 1358MP) is now being made in China I'm looking for an alternative. Are WIX filters still made in the US (the previous NAPA filter vendor) or have they been offshored as well? Does anyone know where the Polaris...

Purchased a 1358MP for my Polaris Ranger today in Canada. Imagine my disappointment later when I saw that it was made in China... What is the verdict on where WIX filters are being made? Are their filters being marked as to their origin?

Straight up on the bottom of the block, like all small block Chevs until the geniuses decided to switch the side the front drive shaft was on (GMT400 models). After that the oil filter was mounted using a 90* adapter w/ the filter oriented 'horizontally'.

Car in question is a '86 Monte Carlo SS w/ the L69 305 small block Chevy motor. Question about anti-drainback filters. GM/AC Delco has replaced the old standby PF25 filter (no ADBV) with the PF454 filter (ADBV). In this application is there a benefit using the new filter? WIX offers the...

Now where does Mobil Full Synthetic fall? I posted this on another non-automotive forum I'm on but has a lot of gear heads. I'm guessing the middle oil is the 'mid-grade' synthetic. Has labelling in the US changed as well since the improvement from SN to SP service ratings?
