Hi Guys. I just pulled the filter at 13K on the Rogue as it was a bit low on full throttle power and the OE filter was saturated with oil on the dirty side. Wondering if any of you guys noticed if the Japanese filters in the Nissan seemed to be oiled from the factory. This 2.5 has a big plenum for oil/air separation not near the filter box so I don't think it's engine oil. It doesn't smell like engine oil either. Thanks. I might clean the MAF that's a few inches from the TB, next.

not the same thing.
K&N's filter are too heavily oiled, enough to ruin a MAF. The cotton media isn't very good, either. lets too much [censored] in.
Totally different from the OEM oiled air filters, and also Fram TG and Purolator P1 air filters, which are more or less standard media with only a SLIGHT amount of oil on them, not nearly enough to hurt a MAF.

Porsche uses that very same, cotton gauze oiled filter tech in their most expensive vehicle.

Again, no mistake, paper filters better. But K&N and others using this technology are not as bad as the extreme characterizations.
