The K&N 69-0017TS is a Typhoon-series cold-air intake for the turbocharged 2.3-liter four-cylinder in the Acura RDX. It replaces the factory intake tract with a silver, mandrel-bent aluminum tube and an oversized, washable High-Flow filter with oiled cotton media (replacement element RX-4730). The manufacturer describes the system as an aluminum tube induction kit intended to add horsepower and torque.
Compared with a restrictive stock airbox, this kit aims to improve airflow and throttle response, and the reusable filter can be cleaned and re-oiled instead of replaced, which helps offset its cost over time. Its CARB EO number (D-269-39) and 50-state street-legal status are useful for buyers in emissions-strict regions. Manufacturer fitment lists 2007–2011 RDX models with the 2.3L turbo engine, while the product title references 07–08, so confirm your year before ordering. For DIY installers, expect a few hours of work with basic hand tools, careful attention to hose routing, and a check of the included clamps and mounting hardware.

This is a bolt-on job that most home mechanics can complete with basic hand tools, but plan for a few hours and work with the engine cold. Owners on user forums who have installed K&N Typhoon kits on other vehicles report that the supplied hose clamps can be just long enough with no slack, so have longer clamps on hand. Some also note that the mass airflow sensor may need a small Allen wrench rather than the Phillips screws used on the stock tube, and that the engine cover foam can rub against the new tube. Test-fit the tube and check hose clearance before fully tightening anything.
