OVERVIEW
Vacuum non-return valve port plug for the B58 Gen1/2 engine block — installed in place of the OEM BMW valve (part number 11667620923), which factory-routes vacuum from the vacuum pump to the brake booster.
In builds where a vacuum brake booster is not used (drift builds in particular), this port is left unused. Instead of the factory valve, a durable metal plug with an O-ring is installed to seal the vacuum passage.
Machined from 2024-T4 aluminum alloy, anodized. Includes an O-ring for sealing.
Do not use this plug if your car retains factory vacuum brake booster.
