The K&N 69-8616TS is a Typhoon cold air intake for the 2.5L four-cylinder Scion tC. It replaces the factory air filter and intake housing with a mandrel-bent aluminum tube feeding an oversized, oiled cotton filter. The manufacturer says the system is designed to deliver a guaranteed increase in horsepower and torque. Compared with stock, the advantage is a less restrictive path for incoming air, which owners say shows up as quicker throttle response and a more audible intake note. The washable, reusable filter also means a buyer avoids repeat paper-filter purchases, which offsets part of the upfront cost on a daily-driven tC.
The manufacturer lists this kit for the 2011 through 2016 Scion tC with the 2.5L L4 fuel-injected engine, so it is a good match for the long-tail searches a tC owner would run, such as "2011-2016 Scion tC 2.5L cold air intake" or "K&N 69 Series Typhoon intake." Because the kit is a complete tube-and-filter replacement, the installation centers on the engine bay and the factory air path rather than any engine internals. Owners report that the area around the throttle body is the most cramped part of the job, so plan for patience there. Note that this kit is not legal for sale or use in California on pollution-controlled vehicles, so buyers in that state should confirm eligibility before ordering.
The manufacturer describes the filter as washable and reusable, built with oiled cotton filter media. Follow the manufacturer's care guidance for cleaning and re-oiling.

The manufacturer provides an installation instruction sheet for this kit, and it should be the reference for the step sequence. Expect basic hand tools and a methodical approach, since the throttle body area is tight and owners frequently cite it as the fiddliest step. Keep the factory mass air sensor and crankcase vent connections in mind when removing the stock airbox, and check that all clamps and connections are tight once the system is in place.
