The K&N 69-2026TTK Typhoon kit replaces the factory airbox and filter on the 1.5L three-cylinder MINI engine with a mandrel-bent aluminum intake tube and an oversized, cone-shaped, oiled cotton filter. The manufacturer lists an estimated gain of 6.55 HP at 3200 RPM. The filter is washable and reusable, and the manufacturer rates it for up to 100,000 miles of normal highway driving, so you avoid buying replacement paper filters. Owners on user forums are more cautious, and several describe the main benefit as a deeper, louder intake note rather than a large power gain. If you want a cold air intake for sound and a reusable filter, this kit fits that goal. If you need a measurable power increase, pair it with a tune or other supporting modifications.
Fitment deserves a careful look before you order. The manufacturer lists this application as the MINI Cooper L3-1.5L for 2014 to 2020, while the product title reads 14-15, so confirm your VIN against the manufacturer's fitment data. The kit includes a heat shield that fills the original airbox space, and its mounting bracket must be fastened with the supplied hardware. The manufacturer warns that skipping that hardware can damage the intake tube, throttle body, or engine. Its install sheet also says to disconnect the negative battery cable, which erases stored radio and memory settings, so note any anti-theft codes first. Keep the factory intake, which the manufacturer recommends. Finally, the manufacturer states the kit is not legal for sale or use in California on pollution-controlled vehicles.
The manufacturer recommends that customers do not discard the factory air intake.
The manufacturer's install sheet notes that disconnecting the negative battery cable erases pre-programmed electronic memories. Write down your settings first. Some radios need an anti-theft code, which is typically listed in the owner's manual.
The manufacturer states that this kit is not legal for sale or use in California on any pollution-controlled motor vehicle.
Owners on user forums report mixed experiences. One owner reported that the car felt heavier and sluggish in Green and Normal modes but responsive in Sport mode, and attributed the change to the ECU adjusting after the install.
The manufacturer's install sheet lists a step-by-step procedure with a parts table, and its listing states that a typical installation takes 60 minutes or less with simple hand tools. Start by disconnecting the negative battery cable and noting radio codes. Remove the stock airbox and intake tube, then keep the factory parts as the manufacturer recommends. Attach the heat shield mounting bracket to the heat shield with the supplied hardware, because the manufacturer warns that improper hardware use can damage the intake tube, throttle body, or engine. After reconnecting the battery, start the engine in neutral or park and listen for air leaks or unusual noises. Recheck clamp tightness and clearance after a road test, since the manufacturer advises periodic checks for alignment and tightening.
