Argenta said:Nothing wrong with K&N filters IF your engine has a map-sensor inlet, but the S54 has a Bosch airmassmeter/MAF. This WILL eventually clog up from the oil in the K&N filter, and misread. Just a question of time.ChawenHalo said:barneybear said:As long as folk think they increase power, they will always sell!
And whats wrong with a K&N / Green coton type filter? No replacement needed; easy servicing (not sure about more power but it does get you more intake noise).![]()
I got the engine light on last year, from previous owners using 'very sporty' filters.
cleaned everything up and from now on only dry/paper filters in my car. Engine light out!
It won't if you oil the filter correctly.
