The Wolverine Airsoft INFERNO XTS HPA Engine for MTW Upgrade Kit is designed for MTW users who want to upgrade their existing INFERNO Gen 2 engine to Wolverine’s newer XTS platform. The kit includes the engine without a solenoid, allowing you to reuse the solenoid from your current INFERNO Gen 2 setup.
Upgrade your MTW with the INFERNO XTS
The INFERNO XTS builds on everything that made the INFERNO Gen 2 a trusted and highly respected HPA engine. It delivers the same proven reliability and performance, but adds more forgiveness, tunability and future upgrade potential for modern MTW builds.
Based on Wolverine’s patented independent poppet and nozzle system, the INFERNO XTS refines every stage of the shot cycle. Its extended stroke design improves hop-up air seal, increases feeding forgiveness and creates clearer separation between the loading and firing movements. This helps stabilize each BB before firing, resulting in tighter groupings and more consistent shots.
The newly engineered valve housing optimizes internal airflow, reduces wasted air and makes dwell tuning more forgiving across different setups. Whether you are tuning for competitive performance, adjusting the rifle to local energy limits or simply looking for a more consistent MTW, the INFERNO XTS gives you refined control and reliable performance.
The INFERNO XTS also includes a recoil output port, making it compatible with the QUAKE MTW Recoil Stock. This means the engine can be used as a future-ready upgrade if you want to add a recoil system to your MTW later.
