Poor fit, not impressed

This air filter had bits of rubber debris on the flange that would have ended up in the engine if I hadn't cleaned it first. After removing the stock o ring as instructed, the rubber lip on the flange of the KN filter would not seat into the groove that the o ring came out of on account of the excess rubber material left over on the flange from the injection process.
When this filter requires servicing I'll replace with a new OEM filter that has a reliable fit and seal.

Works like it should

I have bought k&n products for every vehical I have owned. They have yet to let me down.

My 2009 gl1800 deserved no less. I have never owned a wing before, and just getting to the air filter was time consuming. I watched the video and it wasn’t near as bad as I thought. Some people say they had to cut this to fit, not so. The raised lettering on the rubber goes up!

Perfect fit.

Very happy with k&n, and wingstuff fast delivery.

Good find after attempted rip off

After my local dealer tried to rip me off by trying to charge me $40,- for a OEM air filter i found this baby on here, ordered and installed it.Lots of stuff to take off to get to the right place but its an interesting experience to do some things yourself instead of paying someone an outrageous amount of money for it.
I love this air filter....my wing feels like it got a bit more "get up'n go" power because it sucks in more air now.
Also....this filter is washable and should last a long time. Well worth the money.

no problem

Being a auto technician ...changing the K&N on the GL1800 seem no harder then changing a cabin filter on a volvo

A different improvement in performance and mostly gas mileage ( Big must!!)
