no, its literally not possible to buy a better air filter.
Air filter technology is highly specialized and thus extremely difficult to do properly. I mean, think about what a filter is made of. Foam, glue, and plastic.... all HIGHLY specialized materials. Only certain companies have access to the best quality foam, let along the best quality glue and plastic.
You should definitely just stick to twin air. You should also ONLY drive Ford trucks, wear Levi jeans, ride Harley motorcycles, and drink Budweiser beer. Literally nothing else could POSSIBLY be as good as those brands, much like no filter on earth could ever be as good as a twin air.
