Uni Filter NU 4115ST 2 Stage Air Review

UNI makes great ATV filters and this one is no exception. Great replacement filter for Honda ATC-250ES, much better than the original filter. This filter requires a metal baffle from the original filter and obviously needs lubrication.

This is a good quality air filter. I used a 250 for my big red tricycle and it fit perfectly. NOTE: It does not come pre-lubricated with oil, so you need to purchase oil separately. UNI is a good brand and they hold up well. I would recommend this air filter to anyone.

This air filter was a quick replacement for the Honda ATC 250 ES Big Red. The Honda store asked $35 for it and I believe this UNI air filter is the best quality at half the price. I used a different filter oil that was a little thinner than I thought the filter needed. I'm not sure about the UNI oil spray, but I'm hoping the oil I'm using doesn't break down the foam too quickly.

It's a bit expensive BUT this filter was the right one for the Honda Big Red 250ES. All of the other filters are too small for the metal mesh that comes with the standard airbox, but this one fits like a glove. I've been trying for weeks to find the right filter and after speaking to quite a few people on the forums and groups I'm in everyone and their moms recommended this filter and it really worked! Save yourself the headache, it's 100% worth it
