New and Improved Air Filter Kit!!

This filter kit is smaller than the previous model so there is now a gap between the filter and the oem filter cover. This allows for better airflow around the entire filter, and more time between filter cleanings (see photos).

This air filter kit includes one filter cage (Egan Performance Saws, made in USA) and one pre-oiled Uni Filter (made in Australia), as well as one o-ring that fits around the knob that secures the cover to the saw.  (See photos showing how to install this o-ring on the knob)

This kit is designed to fit under the OEM air filter cover on Stihl models 500 and 661.  Testing has shown that the Uni Filter does a better job of filtering out fine particulates than the OEM filter, while also improving performance.

Limit of 2 kits/order please.

Please note: on 661s, the round black plastic piece that's underneath the oem filter will need to be removed prior to installing these filters.

Please note: Back orders will be filled in the order that they are received.  Please allow 2-6 weeks for shipment if back ordered.

Good stuff!

Does what it's supposed to do.

HUGE DIFFERENCE!!

That straight shot and air filter combo really opened up that 500i. That 500i now has no problem burying that 32in bar.

Great Fit

Put on a new 500i prior to ever running. It should perform very good and clean for a long time with good cleaning and oiling as needed. Great fit of the filter and rubber nut washer.
