The K&N 77-9034KP is a 77 Series High-Flow Performance intake for the 4.0L V6 in the FJ Cruiser and 4Runner. It replaces the factory filter and intake tube with a mandrel-bent aluminum tube and an oversized, washable oiled-cotton filter, a mandrel-bent aluminum intake tube and a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The manufacturer's estimated gain is 11.13 HP @ 4862 RPM and 13.2 lbft of torque. Owners on user forums are less certain: one says a K&N intake will make an engine sound meaner although it doesnt make it much if any faster, and another suggests a drop in filter for the stock setup as the cheaper route. Buy this kit for the sound, airflow, and a reusable filter, not for guaranteed power.

No. The manufacturer states this kit was not designed to fit vehicles with a body lift.
The manufacturer states the filter only requires cleaning about every 100,000 miles under normal highway driving conditions. Dusty off-road use may call for more frequent checks.

The manufacturer's instruction sheet calls for a standard hand-tool set: ratchet and extension, 13mm, 12mm, and 10mm sockets, a 10mm wrench, a 3mm Allen wrench, pliers, and a flat-blade screwdriver. Start by turning off the ignition and disconnecting the negative battery cable, but write down your radio and memory settings first, because disconnecting the battery erases preset memories and some radios will ask for an anti-theft code after reconnecting. The sheet also has you lift off the engine cover, unhook the fuel pressure vent line from the fuel pressure regulator, and move the mass air sensor into the new intake tube. Work carefully around these connections and check that every clamp is tight before starting the engine. Because the kit is not designed for body-lifted trucks, confirm your suspension setup first.
