K&N Grease?

809 Views 8 Replies 5 Participants Last post by  ducpainter,

This summer I replaced my air filter with a K&N filter. The filter came with a small tube of grease. The instructions said to grease the permiter of the filter. I did.

Is this necessary, does the filter not fit well enough to seal?

Has anyone not applied the grease?

Super Lube is what was provided by K&N to use.

It looks like a tight fit between the filter and the air box. Why should I apply this lube. It hasn't made a mess to date but I'm sure someday the grease will work it's way to where I don't want it.

I believe the grease closes any little gaps/imperfections between the filter and the air box and stops any dirt from entering the filter via the seal by providing a tighter fit. I don't think you need a whole lot of grease, just a thin coat.

Again, I'm just guessing.

But it does remind me of a joke involving a penguin and his car...

The 'structions say it's to seal near the screw recesses that hold the plastic filter support to the airbox. I used it. I even added a little in the subsequent airbox removals to get the jetting right.

There's still some junk in the airbox. I know a couple of knowledgeable people that don't care for K&N filters because of that. If I go to a more effective filter I'll probably have to re-jet, and I'm too lazy.

I have the same holy air box cover as you and ride in the rain with the OEM paper filter without problems. I think BCM likes BMC filters for the reason you mentioned. I doubt the filter itself will require re jetting since the big change is opening the air box.

When I see one for the 25 or 30 dollars I paid for the K&N I'll try it. [thumbsup]

Bruce was one of the knowledgeable ones I referred to.
