Description K&N 57S-4900 Performance Air Intake System OPEL ASTRA H 2.0L F/I 2004-2010

The K&N 57S-4900 Performance Airbox replaces the restrictive factory air filter and air box. K&N performance air boxes are designed to dramatically reduce air flow restriction and smooth and straighten air flow. This allows the engine to inhale a larger amount of air than the factory air filter assembly, resulting in more usable power and acceleration throughout the engine's RPM range.

The 57S-4900 Performance Airbox includes a custom shaped K&N high-flow air filter and a fully enclosed injection molded air box that connects to the factory air intake hose. The air box features a removable lid for easy access to the filter when cleaning is required. The air filter can be used for up to 100,000 miles before servicing is needed, depending on driving conditions. Installation is relatively easy with commonly available tools.

Some K&N 57S Series Performance Airboxes are compliant with the latest TUV emissions and sound regulations. Refer to the K&N catalog or website for vehicle applications and specific TUV status for each vehicle and air intake.
