OP- why are you switching from Mann to K&N?
Not really a switch. K&N was available locally for $7. Looked nice and made in Korea so I figured I'd see how it goes on a relatively short change.
Though it might be an omen. Last time I used a K&N cartridge I sold the car a month later... lol
In 5k miles (175k) it's getting a big service and I'm installing the LN spin-on adapter so I can run 3506/3675 canisters.
