The TRANS-DAPT Chrome Breather Cap with Grom (SKU TRA4871) is an essential engine ventilation component designed for custom engine builders and performance enthusiasts who demand both function and visual appeal. This breather cap manages crankcase pressure while serving as a polished finishing touch to any high-performance or show-quality engine bay.

This breather cap suits any mechanic or builder working with small-block or big-block engines where traditional breather systems would compromise aesthetic goals. Installation is straightforward—simply push the grommet-sealed cap onto your valve cover breather port for an immediate upgrade in both performance and appearance. Compatible with most aftermarket and original equipment valve covers featuring standard breather openings, the TRANS-DAPT Chrome Breather Cap with Grom delivers professional-grade engine compartment finishing at an affordable price point.
