Fitment: This high - quality Perrin after - MAF hose fits 2002 - 2007 Subaru WRX and 2004 - 2007 Subaru STI models. Features: Constructed with 5 - ply silicone in black or red, it offers a smooth interior surface. This smoothness increases airflow, which means better engine performance, quicker acceleration, and less turbo lag. Installation is a breeze, taking only about 10 minutes, and no tuning is required. What's in the Box: You'll get one Perrin after - MAF intake tube, two clamps, and warranty and instruction documents. This hose replaces the stock corrugated rubber hose between the turbo inlet and the factory air box. With a larger internal volume and a smooth interior, it allows for improved and smoother airflow. It's designed for use with the stock air box but also works with any intake that uses the stock rubber hose.

Using this Perrin after - MAF hose is easy. First, make sure your car engine is turned off and cooled down. Then, remove the stock corrugated rubber hose between the turbo inlet and the factory air box. Next, take the Perrin after - MAF intake tube from the box and install it in place of the old hose, using the two provided clamps to secure it properly. The whole process should take around 10 minutes as estimated. There's no need to tune your car after installation. When it comes to maintenance, periodically check the clamps to ensure they are tight. Also, keep an eye on the silicone hose for any signs of wear or damage. If you notice any issues, contact the manufacturer according to the warranty instructions. Remember, this hose is designed for the specific Subaru WRX and STI models mentioned, so don't try to use it on other vehicles.
