My new JLT filter was massively over-oiled from the factory leaving significant visible oil in the intake tube and TB blade, to the point I needed to wipe it out with a cloth. It had no impact on MAF accuracy. And cleaning the MAF resulted in no difference afterwards either. My wideband tracked everything identically before and after I noticed the excessive intake oil. So I think we can retire that old wives tale.  |
I agree! I've had K&N oiled filters on intakes for 3 vehicles I've owned(combined 12 years of oiled/re-oiled filters). Whether they were new filters with the kits or filters that I have cleaned and re-oiled, I have NEVER had any issues with oiled filters messing up the MAF.
