The APR Throttle Body Pipe replaces the factory plastic pipe with a high quality aluminum pipe that's a constant diameter within. We pay close attention to the airflow path and provide as few bends and tight radius turns as possible to maximize performance. Unlike the factory plastic pipes, ours won't melt and crack under extreme conditions, and ours don't contain a failure-prone and resistive internal piece like the factory pipe. The pipe features an additional port which can be used for an additional sensor, water/methanol injection, or however you see fit, and includes an NPT tap to block it off when not in use. The pipe features bead rolled connection points to help resist hose slippage, and all mounting brackets and billet sensor ports are tig-welded to the pipe for a strong connection. Finally, the pipe is finished in an attractive satin-black finish. This all results in a more reliable setup and increased performance through a smooth and strong uninterrupted airflow path. This pipe is compatible with both OEM and upgraded APR charge hoses.. Removes the restrictive and failure prone throttle body inlet internals (TB inlet pipe).
