I changed the air filter myself for the fist time in my Accord, I got a Honda OEM unit of course
After cleaning the MAF sensor and installing the new air filter, I checked to make sure the fit was snug, thats when I noticed a crack. I looked closer and saw that the "lip" of the top of the air filter housing was gone, I can feel the rubber seal of the filter even with everything nice and tight. Not sure how long its been broke but if you go back and look at my UOA the silicon is not high. I am due for an oil change in about 600 miles and I will be doing a UOA so it would show high silicon if its not making a tight seal right?
