Lightly-oiled air filters like Fram TG/Ultra, STP Premium, and the old blue P1's that Purolator doesn't make anymore.
Keep in mind these are NOT saturated in oil like K&N, but a much lower amount of oil. The heavily-oiled K&N is known to cause MAF failure besides just being poor media that lets too much dirt in the engine.
The lightly-oiled media, by contrast, is supposed to be MAF-safe. But that is my concern now. I think my MAF may be no good after about 35k and 3 years on it. I bought a Bosch MAF, which happens to be a reboxed OEM MAF. Car has 285k now, had about 250k when I installed the MAF. 1996 I30/Maxima, has a Fram TG air filter with the yellow media. Before that, it had the pretty blue P1 air filter.
And now I'm not sure whether the air filters may have caused the MAF failure. While this sensor failure is common on these cars, 35k still seems too soon.
