The K&N 69 - 1040TWR Typhoon cold - air intake system is a top - notch air induction solution for select Honda S2000 models. It swaps out the restrictive factory air filter and housing. This intake pulls in outside air, smoothing and straightening the airflow to cut down on restrictions. As a result, your engine can suck in more air than the factory setup. More air means a power boost and better acceleration across the RPM range. The 69 - 1040TWR features a black rubber - topped K&N high - flow air filter near the driver - side wheel well. It directs outside air through free - flowing aluminum tubes into a short ram induction tube, sending lots of clean air to the engine's throttle body for a guaranteed power gain. The large cone - shaped air filter comes with a water - repellent DryCharger wrap to keep moisture out. Depending on driving conditions, you can use the air filter up to 100,000 miles before servicing. Note that some Typhoon air intakes aren't legal in California and states with similar emission standards, while others are CARB - exempt and legal in all 50 states. Check the K&N catalog or website for your vehicle's specific CARB status and application.

Using this K&N Typhoon cold - air intake is easy. First, remove the restrictive factory air filter and housing. Then, install the new intake system near the driver - side wheel well. Make sure all the connections are secure. When it comes to driving, you'll notice better power and acceleration right away. For maintenance, check the air filter regularly. Depending on your driving conditions, you can use it up to 100,000 miles before servicing. If you see dirt or debris on the filter, it's time to clean it. The filter has a water - repellent DryCharger wrap, but try to avoid deep water puddles to keep it in good shape. Also, remember to check the K&N catalog or website to see if your intake is legal in your state, as some areas have strict emission standards.
