5. Операција

Once installed, the aFe Power Silver Bullet Throttle Body Spacer works by creating a vortex effect in the incoming air charge, which helps to atomize fuel more effectively. Users may notice an improvement in throttle response and potentially a unique sound from the air intake system, particularly under acceleration. The spacer operates passively and requires no user interaction after installation.

6. Одржување

The aFe Power Silver Bullet Throttle Body Spacer is designed for long-term durability and generally requires minimal maintenance. It is recommended to periodically inspect the spacer and surrounding components during routine vehicle maintenance (e.g., air filter changes) to ensure:
