500i/661 Air Cleaner System

Quick and easy added protection!

This Air Filter system is a must have in dry dusty conditions! Installed one of these on my 309 Machine ported Stihl 661C and it's awesome. Super easy to install, fits and functions as it should. Now make one for my Husqvarna 564XP! Thank you guys.

Awesome fit and quality

Air filter kit is great quality and fit , ease of ordering kit with oil was a big add for me having one place to source all my saw needs, keep the quality parts coming WCS

Nice Flter

I installed your filter on my 500 i. Ran 3 tanks of gas now seems to work very well. This filter is a must on the 500i the filter from Stihl is junk.
