Hey Guys, I have heard, and it seems possible that the oil used in a "recharging" a K&N filter can foul the MAF. Have any of you had any experience with this? My last MAF went bad pretty soon after I oiled my last K&N on my S4. My TT need a cleaning and are weighing the options of cleaning vs replacing with a dry filter. Let me know you thoughts and experiences with filter cleaning. Thanks!
