BBK 1534 Twin 52mm Throttle Body - High Flow Power Plus Series for GM 305/350 TPI

The BBK 1534 Twin 52mm Throttle Body - High Flow Power Plus Series for GM 305350 TPI has garnered a mixed response from customers, with many users noting significant performance improvements, while others have encountered frustrating issues regarding quality control. Several reviewers remarked that after installing this throttle body, their vehicles, particularly the 1985 C4 Corvette, achieved a stable idle, a problem they had struggled with prior to the upgrade. This indicates that the BBK throttle body indeed has a positive impact on engine performance and responsiveness, particularly noted during acceleration in higher gears. However, it’s important to mention the challenges faced during installation; some customers required additional components like a specific coupler to fit properly, and there were reports of inadequate items included in the package. For instance, one reviewer noted that essential parts such as the gasket were missing and that screws were poorly threaded into the body, emphasizing a lapse in quality control that could deter potential buyers. Additionally, installation complexities were highlighted, as users pointed out incompatibility with stock intake ducts and the need for creative solutions when reassembling components. The product is praised for its aesthetic appeal and the performance boost it provides, yet it comes with the caveat of needing additional effort to ensure a seamless installation. Overall, while the BBK 1534 throttle body is recognized for enhancing engine performance and driving dynamics, potential buyers should be wary of installation challenges and quality issues to ensure they are well equipped for the upgrade process. **
