The K&N 69-3529TP is a Typhoon cold-air intake built around a mandrel-bent aluminum tube and a reusable oiled cotton-gauze filter. It replaces the factory filter and intake tube on the 3.7L V6 Mustang. The manufacturer backs the kit with a guaranteed horsepower and torque increase and a No-Hassle Lifetime Limited Warranty. Compared with a generic cone filter, this is a matched intake tube and filter system, and the filter is meant to be cleaned and reused rather than replaced on a short schedule. Enthusiasts searching for a 3.7L V6 Mustang cold air intake, a K&N Typhoon 69 Series upgrade, or a reusable oiled cotton air filter setup will find that design is the main reason to choose it.
Confirm your model year before ordering. The manufacturer's listing for this part covers 2011–2014 Ford Mustang 3.7L V6 models, while the title on this page references 2011–2012. Installation is mostly a hand-tool job, and the manufacturer estimates about 60 minutes or less. The install sheet calls for a 10mm socket and extension, a flat-blade screwdriver, a 5/8" wrench, a 3mm Allen key, and pliers. Disconnect the negative battery cable first, and note that this can erase radio presets. The plastic NPT vent fitting cross-threads easily, so hand-start it and then turn it two full turns with a wrench.
The manufacturer states the filter only needs cleaning about every 100,000 miles under normal highway driving conditions. The filter is washable and reusable, so it does not need to be replaced at that interval.
The manufacturer recommends that customers do not discard the factory air intake, even though the kit replaces it.

Per the manufacturer's install sheet, this is a moderate-difficulty, bolt-on project that the manufacturer estimates takes about an hour. Start by turning off the ignition and disconnecting the negative battery cable, and record radio and memory settings first, since some radios will ask for an anti-theft code afterward. Disconnect the mass air sensor connector and loosen the clamp that secures the factory tube to the throttle body. Mount the two provided studs to the bottom of the new air box, then install the silicone hose onto the throttle body. The sheet has you fit the vent fitting and plug, depending on whether your car has an EVAP vent line. Hand-tighten the plastic NPT fitting first, because it cross-threads easily. Keep the factory tube stored rather than discarding it, since the manufacturer recommends retaining it.
