Show original supplier description
The CTS Turbo N20 Atmospheric BOV KIT is engineered as a direct replacement for the factory plastic blow-off valve on BMW N20 engines. The stock unit is known for its susceptibility to failure due to torn diaphragms, cracked plastic, and electrical issues, leading to performance degradation. This aftermarket solution offers enhanced durability and reliability through its billet construction. Designed to work seamlessly with all factory electronics, the CTS Turbo BOV KIT ensures straightforward integration into your N20's engine bay. Its compact design is slightly shorter than the stock valve, allowing for a snug fit even in the confined N20 engine compartment. The valve is also completely serviceable, allowing for easier maintenance and longevity. This blow-off valve kit is specifically designed for BMW vehicles equipped with the N20 engine, including models such as the 328i (2012-2016 F30), 428i, and 528i.
