TiAL 003889 MV-S External Wastegate V-Band - 38mm

The TiAL MV-S 38mm External Wastegate is a compact, high-performance boost control solution engineered for turbocharged applications. At only 3.7 inches in height, the MV-S is significantly more compact than its F38 predecessor, making it an ideal choice for tight engine bays where packaging space is at a premium.
