Product Description
The Rtunes Racing cold air intake replaces the factory airbox and intake tubing on the 2004-2008 Acura TSX CL9. Its mandrel-bent pipe provides a more direct airflow path to the 2.4L K24A2 engine, while the reusable high-flow filter replaces the factory disposable filter.
The open filter and intake pipe produce a louder intake sound when accelerating, especially as the K24A2 moves through the upper RPM range. The filter can be cleaned and reused during routine maintenance instead of being replaced.
The kit includes the intake pipe, high-flow filter, mounting hardware, vacuum hoses and reducers shown in the product photos. Red, blue and black pipe options are available.
Before You Buy
- Verify that your TSX is a 2004-2008 CL9 model with the 2.4L K24A2 engine
- Select your preferred intake pipe color before adding the kit to your cart
- Compare the included connections and hardware with your factory intake before beginning installation
- Keep a low-mounted air filter away from deep standing water to reduce the risk of water ingestion
- Clean and service the reusable filter according to the filter manufacturer's recommendations
- Check the intake clamps and mounting hardware after the first few heat cycles
