Product Description

The BLOX Racing BXPT-10403 titanium valve retainers are engineered for Honda/Acura B-Series DOHC engines, including popular B18A/B and B20 variants found in Integra and early CR-V applications. Made from premium titanium and precision machined, these retainers drastically reduce reciprocating valvetrain mass compared to stock retainers, resulting in improved high-RPM stability and reduced valve float under performance conditions. Whether your build is naturally aspirated or modified with aggressive camshafts, these retainers help maintain valvetrain control where it matters most.

This full set of 16 valve retainers is a direct OEM-style fit for B-Series engines and installs without the need for machining, making it a straightforward performance upgrade for engine builders and enthusiasts alike. The lightweight design allows the engine to rev more freely and offers an edge in both street performance and competitive environments, especially when paired with upgraded valve springs. Always verify your specific engine code before installation to ensure compatibility.
