As advertised. Don’t forget the K & N oil. It does not come with the filter. You can find it at a local auto parts store if you forgot it here on ACS. These filters shrink in size over time. You’ll probably get 3 years out of it. Maybe longer?

I bought the E-3450 filter element to replace the old filter in my RV6, which has a Lycoming O-360 engine. Works well!

Q: I need to replace the air filter on my Vans RV-4. I have tried the E-3450 from Autozone and it is just a bit small. Some Vans Aircraft RV owners have stated that the one I need is slightly larger and you have the correct size. The E-3450 I need has the following number stamped on the bottom: A077A6-B Evidently the smaller ones do not have the B suffix at the end. Would you mind checking before I order so I can make sure I get the correct air filter?

Yes, this product is stamped A077A6-B at the bottom.

Q: Is this K&N E-3450 filter for rv9?

This filter is for 0-360/0-540 engines. Please confirm your engine on the RV9.

Q: Does this filter need to be pre oiled before installing from sealed package?

No, this filter is pre-oiled.
