Default Re: cleaning a k&n air filter

Actually the test results are valid because the AC Delco A1618C is the exact same size as the K&N 33-2135.

Just because the H2 uses a larger filter doesn't mean you can ignore the test results, the pass-thru is still valid regardless of the media surface area, and other test values will follow a linear relationship based on filter size.

The stock paper filter design wins hands down in all aspects against any gauze and oil filter.

K&N air filters do a poor job filtering, and poor filters = shorter engine life.
