K&N filter - to lube or not?

[timvan]

My LTR has a K&N filter on it which I took off and cleaned up last night. I dont think it ever had any love, but it still wasnt nearly as dirty as any auto filter.

Considering a lot of boats only run a flame arrestor, do you think the filter needs oil to increase its filtering and reduce its airflow - or run it rather dry and call it a makeshift flame arrestor?

Oil It, it will still get plenty of air.

It has to be oiled to filter properly

Yup, oil it.

Oil it but don't get too crazy. It's easy to get carried away then have the oil fowl the MAS. This can cause the engine to run rich and idle poorly. I started cleaning with MAS with a dedicated MAS spray cleaner about a week after cleaning and oiling my K&N filters on my cars and boat.

Hmmm...so what exactly is the filter filtering from air entering a motor box in a boat? I've always oiled filters on dirt bikes and lawn mowers for obvious reasons, but a boat? I don't have an LTR or a K&N, but was surprised by the responses.

My thoughts as well, thus why I asked. If the lake is dusty, im doing something wrong

They are designed to work with oil, they are not like a regular filter.


I don't see the stuff in the air in my house either but I know after a week there is a dust layer on top of the fridge.........

I would lightly oil it. Notice the word lightly. People have a tendency to over charge k&n's in my book. Boat collects dust and dirt. Both go to the bilge. If they get dry and shook from a rough wake---they might get airborne. Engines suck lots of air--especially under load and making hp. Dirty air is a wear item and you already have a good filter. Why not use it.

Lightly spay until there is a light even coat of red.
