The AE32337-C VHM insert is engineered with a lower volume of 21.40cc, providing a higher compression ratio to significantly boost bottom-end and mid-range torque. This insert is particularly suited for deep sand tracks or technical circuits, where rapid acceleration and low-end pull are key.

It’s fully compatible with the VHM cylinder head AA33209 and not suitable for OEM heads. The insert’s engraved part number allows for easy identification and replacement. For optimal performance, it is essential to use 105 RON fuel, ensuring resistance to detonation under high compression.
