This is a red oiled disposable air filter available on Amazon. Has anybody used one of these? It looks promising. About the same price as a Mann AF for my MB.
This brings up a good point with these modern vehicles. 40 years ago it wouldn't matter. But with today's new complex vehicles that are laden with sensors, it's better to stick with OEM. It would also negate any warranty issues that might come up in regards to using aftermarket, non OEM parts.
I don't think the disposable oiled air filters are "dripping" with oil ... just enough to wet and soak into the media. Doubt they are going to pose and problems. It would be way more likely for an over-oiled K&N to cause excess oil issues.
