Default O-360 RV-8 K&N filter question

I purchased a flying RV-8 last year and am now preparing for the annual condition inspection. This aircraft has a Lycoming O-360 and the standard Vans airbox.

I want to purchase a second K&N air filter, but does this setup require cutting a notch and sealing the filter like on the O-320? I previously had an RV-6A with the O-320 that required a notched filter.

If the notch is required, what is the correct sealant to use?

Unfortunately this aircraft did not come with the builder plans and the drawings I purchased on a flash drive from Vans did not include the FAB plans.

Depends on the carburetor used. I think typically the answer is no, you dont need to cut the filter. But if the accelerator pump is in the way then you will need to cut it. The correct sealant to use is pro seal, the same sealant used in the fuel tanks.


Do not use RTV, it can break down from the fuel and get sucked into the intake.

The filtered air box was ordered separately from the kit. See this Van's web page for applicability. You can probably contact Van's for a set of FAB plans.

Below is a link to the filter element (E-3450):

No the filter does not get trimmed with the 360 carb.
