I just hosed the K&N cone filter from the inside out and it is now soaking in a bucket with some dish sope I didnt have any simple green. im gonna let it dry for a few hours maby 2-3 hours do you think that is enough? also Is it nessary to reoil the filter after cleaning? If so can i get away with it for a day or 2 with out doing it?? and if i need to reoil the filter how do I go about doing it? Thanks guys. Im also in the process of checking my plugs 3 down 5 to go just did an oil change and makeing sure thare tight damb 2000L's with the less threds!!
