bosch or pure one are just as good, and only cost half as much. the air filter is a lot more important that the oil filter. even supertech at wallymart is a good oil filter.
There has been speculation that the K&N filter is the same as Mobil 1, with the exception that it has a nut on the can like an aircraft filter. Is there any insight about whether, or not the media is the same? Autozone is running a $29.99 sale for 5 Qt.s of PP and a K&N filter (up to $14.99 value). I've been using PP and M1 filters exclusively with geat results in my Tacoma.
