There is a spring in the filter? What does it do?magilson said:So no need to worry about the spring in the filter being too tight or anything?
any chance you could see what a K&N guts look like? and see if you can "rinse and reuse those you know just add oil......" lolT-Keith said:You should fill to the full line. It's OK to be a little under but filling to the full line is preferred. Remember to start the car then shut it off and let it sit a while before checking. Since the engine usually takes 4-1/2 quarts with the standard length, and the longer filter is barley and inch longer I have a hard time believing it would take a full 5 quarts. Always check for clearance before installing a larger filter, some people have problems. I just use a filter with more area like the Purolator instead of risking filter damage.
thanks for the compliment Ron, you seem like a knowledgeable guy and I see your idea, just thought I'd clear up the area issue.
