The K&N 69 - 8751TR Typhoon air intake system is a top - notch, free - flowing air induction solution for select Toyota Corolla models. It replaces the restrictive factory air filter and housing, smoothing and straightening airflow to significantly cut down on restrictions. This enables your engine to take in more air, boosting power and acceleration across the RPM range. The intake comes with a black rubber - topped K&N high - flow air filter that fits neatly into the old air box space. Air is channeled through the red powder - coated intake tube, which is built to last and compatible with the factory mass air sensor, directly into the engine's throttle body for a guaranteed power increase. The oversized cone - shaped air filter can go up to 100,000 miles before service, depending on your driving. Installation is a breeze, usually taking 90 minutes or less with basic tools like screwdrivers, pliers, a ratchet set, and an Allen wrench. Note that some Typhoon air intakes may not be legal in California and other states with similar emission standards, while others are CARB - exempt and 50 - state legal. Check the K&N catalog or website for specific details.
