Overview

The MAPerformance BOV Block Off Plate is designed for the 2016-2021 Honda Civic 1.5T. It plugs and seals the factory diverter valve, preparing the system for future modifications such as mounting a new, higher volume/pressure Blow-Off Valve (BOV).
Show original supplier description
The MAPerformance BOV Block Off Plate is engineered for the 2016-2021 Honda Civic 1.5T, including the Civic Si model from 2017-2021. This component is crucial for drivers planning performance upgrades, as it effectively seals the factory diverter valve. This prepares the charge pipe system for the installation of a higher volume or higher pressure aftermarket Blow-Off Valve (BOV). The plate includes stainless steel mounting screws intended for long-lasting durability. This kit includes one MAP Civic Si 1.5T BOV Block Off Plate with pre-installed seals and three mounting screws. It is specifically designed for FWD models of the 2016-2021 Honda Civic.
