made some excellent filters with this. wish all OEM filters were made of this stuff. The filtration of the fine product is excellent and it will save your engine in dusty conditions. It prevents the entry of sand and dust into your engine so it doesn't grind your piston rings into powder, and can lengthen your engine life to easily 300K miles if you use it along with Mobil One Synthetic Oils. You can wash and reuse it several times. Do that every 20K miles or less. you can make different shapes and glue it together to make round air cleaner filter covers. once you put it on over your round style filter, the paper never gets dirty. on flat style filters you just tale out the filter, cut a piece to fit under the paper filter with a pair of scissors, and put the paper filter back in on top of it and away you go. Some filters don't have enough room for the foam to fit under or around without blocking the air passageways pretty badly, and this will cause a check engine light when the oxygen sensor causes the fuel map to go out of range. In this case you might need to make an external housing or mount it in a different way. BUT it is still a great product!

There are others, but this is the best quality foam out there. Durable and effective.

Have a 30 year old Tanaka. The filter in it was OK till I replaced the primmer bulb. It had to be removed to get to screws. It basically dissolved to dust when I tried to remove. This sheet of filter material allowed me to make a replacement for that filter with 90% or more of sheet left to use in future. Can make quite a few of that filter if needed.

I use it as a pre filter for my 2023 CRF 300 rally. Able to get 6 filters out of this one size. Definitely recommend to anyone with a motorbike.

Purchased this to make an air filter for our 2012 Polaris RZR 800. We made the massive mistake of using a popular after market filter on the machine because it was a washable, reusable foam filter. It let through the fine dust of Utah and cost us a top end job after 1500 miles. The fine print on the other filter says the warranty isn't valid in dusty, off-road conditions. My husband used Uni Filters for years while riding trials motorcycle competitions and so we tried it for the RZR. This works far better than the aforementioned foam filter or the stock paper filter.

Nice, thick and high quality filter media. Allowed me to make a new element for a long out of production part. Cut more easily with scissors than a razor knife to my surprise.

I am happy with the product. The quality is great and the shipping was fast, it worked perfectly for my 40 year old motorcycle. There was enough to make 3 air filters. ðŸ‘ðŸ‘

Worked perfect for a replacement filter. Cut it to size and worked great. Lots left for more custom applications

Bought it for my motorcycle to replace the original paper filter. Cut it to shape but haven't installed yet as I'm waiting for my paper filter to get a bit dirtier before switching over, but the foam seems to be of great quality! I think it will definitely help my engine filter better with a good foam oil.

I used this to make a couple of round air filters, GE silicone works perfect as an adhesive as long as you have a way to hold it in place for a day - cling wrap worked for me.
