Just Purchased First FJ - Came with K&N Performance Air Intake
Hi Community - as it can be seen, this is my very first post. I just purchased my first FJ Cruiser yesterday. It is a 2011 Trail Teams in Army Green with Convenience package and TRD upgrades. Very nice and all but the previous owner put in a K&N Performance Air Intake System (K&N Part 77-9034KP). To avoid MAF problems and possible engine longevity issues, I am looking to return to the stock air intake system. A few questions I am wondering about before the attempt:
-Is engine longevity actually an issue with these systems? If so, would it be better to replace the K&N if the system has been active for at least 20,000 miles?
-How expensive would the stock assembly alone be? I was hoping someone had the stock components I could buy used, rather than searching part-by-part to fill.
-Would taking out the K&N parts not only cost for parts and labor, but require a system recalibration?
