Durability 1/5 Ease of Installation 5/5 Performance 1/5
Filter Foam Separated from Rubber Flange

Been using Twin Air since the 70's. Filter foam separated from the rubber flange on two out of the three filters that I bought. One filter had a gap in a 1 inch section where the filter meets the rubber new right out of the bag. The other fell apart after the first washing. Throwing away the third one. Can't afford to have a bad filter ruin my engine.

I bought the more expensive Twin Air filter based on reputation. My expectations were high because of it being a Twin Air product. The filter itself is fine, but the clamp is junk. The clamp is too small in diameter and makes installation more difficult. The clamp is flimsy compared to the Loudmouth No Toil filter. For 7 to 8 dollars cheaper, I would stick with the No Toil filter and clamp. The No Toil set up is better and cheaper.

Loudmouth filter

Easy to install and clean. I bought this filter as an extra when going to Moab, Utah for three days of riding. It is now my primary air filter.

It works

it's a filter. It fits the loudmouth intake. What more do you want?

Works as intended

Compared to the stock filter you get with the loudmouth system it is clear that this a superior product. The foam feels more durable and it also feels like it will be able to better filter out dust particals. I also noticed it had a tighter fit around the base. Overall good product and I will buy another one in the furture.


Great product, fast shipping

Great Product

Twin air filters are great. This one is used with the loudmouth intake system and fits just as good as the loudmouth filter. only complaint is that the retainer ring is a little too small and takes a second to get on the filter once installed.

A: As long as you use a proper filter cleaner to get the oil off and a little soap and water the filters will last you a long time.

I was looking for a No Toil loudmouth filter but don't see one available. Is this Twin Air filter pre-oiled or can I use No Toil cleaner and oil on this?
