Product Description

The Turbo XS HC15T-HYB-BLK Hybrid BOV is engineered as a superior direct replacement for the stock bypass valve on the 2016-21 Honda Civic 1.5T and 2018-21 Accord Sport. Featuring a robust 44mm piston with Viton seals and dual-mode design, it delivers both aggressive VTA sound and ECU-safe recirculation, eliminating CEL triggers.

Machined from anodized 6061 aluminum with a sleek black finish and USA-made stainless banjo fitting, this valve not only looks OEM-appropriate but stands up to high boost and temperatures. Installation is plug-and-play, aligning perfectly with factory flange and bolt pattern. Firmware integrity is maintained thanks to its hybrid venting system.
