Good upgrade

Put this on my ttr230 to upgrade from the stock filter I had. Bike seems to be breathing better and throttle response has improved

Great Product

Have had really good luck with these filters and raced in California off-on for two years, never failed and withstood the normal cleaning with solvents & soap/water. Good product!!

Gives you way more air flow

This is the air filter I've been looking for. It gives you more horse power and way more air flow. Also it is a item with amazing quality.

Good quality reusable air filter

Quality of product is important and for something as simple as an air filter this is very important to protect your engine. Overall i like how this filter fits and I like how it feels much higher quality than the OEM filter. My

Always A Good Purchase

I bought this filter for my girlfriends 2003 CRF 150F. Fit was just as snug and correct as the stock filter. Holes all matched up no problem. It even came with 2 UNI stickers. I've been running these filters for years and they've never failed me, I don't expect this one to be any different.

1997 Honda xr250r uni air filter

Overall very pleased with a new uni air filter for my XR 250. It fits well and comes with the better than OEM metal cage inside the air filter. You may have to do a little trimming with scissors on the inside of the filter that connects to the air box. Overall very tight fit. I do not recommend and no toil air filter it fell apart after one season. But I still use their oil products on my uni air filter.

Great filter

It's hard to beat an uni the price,durability, and performance!!! The bike has a noticeable change in torque for the better!! It's a little louder at the pipes and I'm saving on fuel!! Plus I ride desert and the filter is great no holes tears rotting !! Outside if the filter is caked but inside is clean!!

Awesome protection

This is a crucial part to any off-road machine, the duel stage setup of UNI is un-beatable at protection and flow. I submerge it in a tub of oil and then squeeze it really tight and run it. will buy more when needed.

Probably the best air filter on the market.

I like how these filters are constructed .... two layers of foam are better than one! The UNI filters seem to last longer than other brands of filters due to the quality of materials used. To help prolong their lifespan, I choose to oil my air filters with No Toil oil instead of standard petroleum based products. That's because the biodegradable cleaner is a lot less stressful on the foam than solvents are. My UNI filters last several seasons without failure because I rotate them (buy two or three), I never oil them far in advance, they are kept in plastic produce bags, and they are kept in a cool dark place to prevent sunlight from breaking down the foam.
Taking air filter maintenance seriously means your engine will perform and last for a long time.

FILTER

This filter is very hard to install once the filter support is installed its very difficult to thread the attaching bolt. I have used this filter on many Hondas but the CRF150R I will think twice before I reorder.

Q: Does it come with a frame to support and seal the airfilter?
Over 5 months ago
The airfilter I have doesn't have a frame and it won't seal on its own so I'm lookin for something that already has a frame and seals without having to buy anything else.
