The products you show are for different purposes. The MHP is CF Inlets before the air boxes and the Eurocharged is CF Air Boxes. Both products are more for looks than performance although mthis says the Inlets do add a little (you will never feel it) HP and the Air Boxes (except for Renntech) do not add any power.




Airboxes unknown from my data, but I suspect about the same (edit: yes, about the same - 0.08 and .75mph)
but should i clean it every 20 mile or its same the stock air filter

No need to clean so often, but as previously said, once a year or so should be good enough.
