You have a couple of choices. I chose Egan because of its design, function and simplicity. Plus, the filter comes pre-oiled, which is nice.
When installed, the included o-ring creates a tight seal at the closure mechanism of the stock 500i cover.
Don't forget to included some Bel Ray foam filter oil in your order for future re-oiling.
Best purchase to make to keep fine sawdust out of your $1700 ms500i fits under stock cover
Really opened up the saw letting it breather more and cleaner with 0 particles passing through filter
I’m really liking the Egan air filter on my new 500i it’s keeping the fines out of fuel injection system witch in return means keeping the fines out of motor for longer engine life I like this product will enough I’ve going to Egans air filters on every saw I have that they a filter for stay safe sawing
Awesome product best fiter out there worth every penny
