Well, I did discover that it takes 2 filters, so I have ordered a second K&N thru O'Reilly's/Schucks Auto parts for $37.99 ( each).
I was really surprised when I took the filter case apart- There were large leaves, and lots of bees that had perished in the filter compartment.
My roadster is mainly driven on nice days, and a few vacations in Washington, Oregon, California, Wyoming , and Montana , so I am assuming I sucked up the debris & insects while on these trips.
Now that I have the cover off, I see that I have some oil build-up on the valve (?) covers, on the opposite side from the oil filler spout. I have 35,706 miles on the odometer.
Or, is that normal blow by ? I rarely take the car over 90 MPH, with spurts up to 135 MPH, but, I assume that may be a cause.
I am wondering if this is leakage, or residue from a sloppy dealer oil change I had once.
What is the best chemical or degreaser to use to clean this up?
