The vehicle previously ran a hot aluminium intake setup , which can often restrict performance due to heat soak and less efficient airflow. To improve the setup, we removed the old intake and installed an ORSSOM OTR (Over-The-Radiator) intake , along with a performance downpipe upgrade . Intake Upgrade Results After completing t

Liam made the trip all the way from Shepparton  to Revhigh for a complete performance transformation, combining a high-flow exhaust system, downpipe upgrade, and VCM OTR intake , finished off with a custom dyno tune .
