Intake manifold porting involves the alteration of the internal channels of the intake manifold. It is well known that performance and airflow require the least amount of obstruction or resistance. Sculpting and polishing intake ports is imperative for smoother and less restrictive flow of air into the cylinders. Increased power can result from porting because of effectiveness in the combustion of the air-fuel mixture. Increased distribution of the air-fuel mixture improves combustion efficacy. This is typical for performance applications and motors requiring surplus power. Every increment of improvement in the flow of air boosts power, I trust you understand how important this process is. Nevertheless, this step has to be done very carefully, as poor effort can destroy a drivetrain through performance loss due to badly designed porting.
