So that's still officially the K&N filter for the 2003-2008 Mazda RX-8. Has K&N officially said the 33-2284 filter is for use with the 08 Viper? (I know K&N was looking for a 2008 Viper a few months ago for testing at their Riverside facility but haven't heard anything since.) You didn't happen to get any before and after dyno results did you? Thanks!
Did it also include a piece of paper stating that even though it may fit another vehicle, it is only intended to be used for the it was designed for? Last few I bought, for different vehicles no less, had such a paper.
Problem is, the RX8 flows no where near as much airflow as the Viper. It may "fit", but it also flows much less CFM. A call to K&N will confirm this.
it is not designed for the viper but does fit perfectly....as for air flow well i guess only a dyno would show for sure...certainly didn't result in any power loss...it is a lot thinner than the stock filter
