I'm confused did you get a drop in K&N filter/ i.e. replaced the oem filter.
or did you order the stillen intake that comes with a cone shaped K&N?
I get it you did both

That is correct. There is a large resonator below the stock airbox that is omitted with the Stillen set-up.esemes said:i think the Stillen setup ditches the baffles/resonators found on the oem airbox setup, rught???

Buy a K&N Air filter cleaning kit at Pep Boys, Auto-Zone, etc. Then remove the filter, spray the cleaner on the filter, than rinse with water. After the filter dries, spray it with the filter oil supplied with the K&N cleaning kit.stormace said:How often will I need to clean the Stillen, and with what?
