Why Upgrade to 4S1M?
Stock throttle bodies restrict your engine to prioritize quiet, conservative performance. When you upgrade your exhaust, bore up, or tweak your fuel management, the stock intake becomes a major bottleneck. The 4S1M 34mm Throttle Body feeds the engine efficiently, optimizing the air-fuel mixture to extract maximum performance from your upgrades.
💡 Mechanic’s Note: For optimum performance and a perfectly stable idle, ECU re-tuning or a fuel management adjustment is highly recommended after installation to perfectly match the increased airflow.
