Description: The WJ Airbox Kit is a further development of the original Gilera Runner back box, with improved performance and easier installation. Thanks to the modified hose, this kit is suitable for carburetors up to 38 mm.
The airbox is also compatible with a VForce adapter, giving you the benefits of a quieter, deeper sound and the airflow of an open power filter – ideal for those seeking performance and comfort.
The included Engine Brace reinforces the engine block and prevents damage such as cracks or twisting in powerful setups.
⚠️ Please note: This kit only fits in combination with the included WJ Engine Brace.
Advantages: ✓ Suitable for carburetors up to 38 mm ✓ Compatible with VForce adapter ✓ Quieter and deeper sound than open filters ✓ Reinforces the engine block under heavy load
