Top Mount Charge Pipe

The ETS Top Mount Charge Pipe is a direct replacement for the restrictive factory plastic/rubber charge pipe, designed to improve airflow, durability, and throttle response on the VB WRX. Constructed from mandrel-bent aluminum with high-quality couplers, it eliminates the flex and expansion seen in the OEM piping under boost. This results in more consistent boost delivery and sharper throttle response, especially on tuned setups running higher boost levels. While gains on a stock tune are modest, the upgrade becomes more noticeable when paired with an upgraded intercooler and tuning. It also can help improve long-term reliability by removing a known weak point in the factory system. Overall, it’s a solid supporting mod that complements intercooler upgrades and helps maintain consistent performance under load.
