VQ35DE Ported, Shaved & Ceramic-Painted Lower Plenum – Performance Enhanced
Unlock the full potential of your VQ35DE with our modified lower plenum, precision-engineered for better airflow distribution and increased horsepower. Designed with performance in mind, we’ve optimized airflow by shaving down the front two horns by 10mm (similar to the Motordyne MREV 2 Plenum) and the four rear horns by 4mm. This modification ensures the front two cylinders—often starved for air—get the airflow they need, leading to a more balanced and efficient combustion process.
Performance Benefits:
✔ Increased Power – Gains of 10-20 HP when paired with supporting intake mods
✔ Optimized Airflow – Reshaped intake horns improve flow balance across all cylinders
✔ Enhanced Throttle Response – Better airflow distribution means smoother power delivery
✔ More Efficient Combustion – Front cylinders receive more air, reducing power imbalances
✔ Lower Intake Temperatures – Optional ceramic paint reduces heat soak, improving efficiency
