🌬️ Uni Filter UP-123 1/2" Push-in Breather: Optimal Airflow Solution for Superior Engine Performance Review

As usual I shopped everywhere but ended up buying this filter from AMAZON as it had the best overall price. The filter fully corresponds to the description and fulfills its function.

Good product but ID (bore size) would be more helpful when ordering. This specifically fits into a 1/2" ID hose and creates a flow restriction.

Worked great on my 2003 Triumph America. It's still there and works great so far. He does his job and it's as simple as that. UNI is the bomb and still offers very reasonable prices compared to K&N or any of these companies.

The product was more than perfect for my KTM 690 SMC crankcase breather. Even if you think this filter is made of soft rubber, you are wrong, it is all hard plastic. Still, it worked better than I planned and was able to slide the bleeder straight into the hose without an adapter. The hose clamp was great too.

FYI: This is the correct size replacement for the Suzuki DR650SE's stock secondary breather filter, which is located under your seat. You may have to fiddle with it a bit when putting the seat on. As with the OEM filter, try to keep it as far from the pipe or airbox opening (if you have modified the airbox) as possible. with this or the OEM. Using this filter and placing it properly can actually eliminate some slight spikes. Bonus.

I found these on another site but the sizes confused me so I did my own research and ordered from Revain. "Push-In" means that the connector is pressed into the inside of the hose or fitting, thus measuring the outside diameter of the filter connector. Then "push-on" would obviously be a measure of the inner diameter of the filter connection.

The product was more than perfect for my KTM 690 SMC crankcase ventilation. But I assumed "1/2" was the inside diameter and actually the outside diameter. Even if you think this filter is made of soft rubber, you are wrong, it is all hard plastic. Still, it worked better than I planned and was able to slide the bleeder straight into the hose without an adapter. The hose clamp was great too.

For reference, this is a replacement for the standard sized Suzuki DR650SE secondary breather filter which is located under your seat. You may have to fiddle with it a bit when you put the seat back on. As with the OEM filter, try to keep it as far from the pipe or airbox opening (if you have modified the airbox) as possible. with this or the OEM. Using this filter and positioning it correctly can actually eliminate some slight spikes. Bonus.
