Fast Motorsports Aftamaf Hose Subaru WRX / STI 2002-2007

The Fast Motorsports Post MAF Hose replaces the stock corrugated rubber piece, connecting the stock airbox to the turbo inlet tube. This part is often considered one of the least attractive OEM components in the engine bay. With its sleek exterior, it looks great, and the smooth interior promotes excellent airflow, delivering a steady stream of air to the turbo. The 4 - ply silicone construction has just the right flexibility to handle the movement between the chassis - mounted airbox and the aggressive boxer engine. The steel reinforcement ensures it won't collapse even when the turbo draws maximum vacuum at wide - open throttle.

Using this Fast Motorsports Post MAF Hose is easy. First, remove the stock corrugated rubber piece that connects the airbox to the turbo inlet tube. Then, simply install the new hose in its place. Make sure it's properly attached to avoid any air leaks. When it comes to maintenance, regularly check for any signs of wear or damage, like cracks in the silicone or loose steel reinforcement. If you notice any issues, it's a good idea to replace the hose. And always be gentle when handling the hose to prevent any unnecessary damage.
