"Air Hog" air filter

"Air Hog" air filter
This afternoon, as I was getting ready to head to Wally World to get a few groceries I took a notion to check the air filter on my '95 Cutlass convertible. It looked kind of grimy so I picked up a replacement while I was there. Both the new filter and the old one are Fram but they couldn't be more different. The old filter turns out to be a Fram "Air Hog" reusable filter. The things were apparently discontinued years ago but the cleaning kits can still be had on eBay for about twice what I paid for a conventional paper filter. I'm not sure how many cleanings you get out of a kit, so it's hard to decide whether it's worth it. Nonetheless, I put the "Air Hog" filter in the new filter's box and stuck it in my tool shed pending a decision. I don't know whether I'll bother to clean it up and reuse it and with a brand new paper filter in place, I really don't feel much pressure to make a decision right now.

I've never seen a fram Air Hog, but if it's like the K&N filters, then reusing them is simple.
You can use any cleaner/degreaser - I use simple green. Spray it on the incoming air side, let sit for a bit, then GENTLY run water from the engine side of the filter to the incoming air side - flushing all the trash out. Don't use a pressure stream - that'll tear the filter.
Let it dry in the sun. Once dry, fog it with the K&N filter oil which you can get just about anywhere for cheap.
K&N's cleaning kit just adds their cleaner. It's nothing special and overpriced, so just use whatever you have. Even 409 or a kitchen cleaner will work fine.

From what little I've been able to gather about them, the Air Hog filters were Fram's attempt to compete with K&N's reusable filters. I remember seeing them advertised in the late '90s and early 2000s, but it seems they were discontinued around 2007, which would make the one I pulled out of the convertible more than a decade old. Good tip on the Simple Green. I'll give that a try and look at putting the Air Hog back in when the paper filter is ready for the bin.

I learned it from driving my Jeep out in the desert. With the K&N there was fine dust inside the air box (on the filtered side) and all the way through the air intake tube to the throttle body. I have never seen that when using a regular paper filter. This may not be a big deal in wetter areas that don't have the amount of dust that we have here in the desert.

made for race applications, you tear them down a lot and rebuild them, it doesn’t matter, not for classics.
I stick with the 542, it has the oiled foam on too.

Human, it looks like you have the exact same car I just bought for my wife. Hers has the 3.4 and 26,000 original miles with original paint. She is the third owner. I looked for one of these cars a long time before the right one came along. I did have to put a battery in it yesterday and that is interesting.
