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 (CF 0690 - 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. Please refer to the video below for proper installation tips.

Limit of 2 kits/order please.  If you order more than 2 kits, or other items with two kits there will be some additional shipping charges, which you will be receive an invoice for.

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

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

Exactly what the saw needed!

Quick shipping, perfect fit and excellent filtering.
Excellent compliment to the cone pipe I built. Free flowing exhaust=need for easier in flow of fresh air.
If you have a 500i dont hesitate to order this filter kit.
