changing stock filter to a K&N filter. did you have to make any modifications to fit the air filter (awfully small space for the filter)
thanks

 

i'm going to guess you mean a cone type filter, as a drop in, well, just drops in. You'll need to remove the stock air box and snorkels, then get yourself a GOOD air flow meter adapter to accept the cone filter. No mods needed if you get the correct size cone filter.

found the product number that correlates to my protege at K&N site. i doubt i need to make any modifications, i hope? what do u think?

 

The part number at K & N for the protege is for the panel filter. That is for the stock air box. It is a flat panel to replace the OEM one in there.
