Show original supplier description
The Redux Racing BMW M42 Adapter ITB Conversion Package is an individual throttle body (ITB) conversion kit precision-engineered for BMW E30 and E36 vehicles. By replacing the stock intake system with individual throttle bodies, this kit eliminates cylinder cross-talk, allowing for more aggressive camshaft profiles without sacrificing low-RPM stability or creating rough idling. The conversion package is available in two configurations: with open trumpets or with an optional carbon fiber plenum. Choosing the open trumpet configuration requires a standalone ECU to achieve maximum performance and ensure proper engine operation. Each kit is designed and assembled in-house to maintain strict quality standards and is backed by a 12-month satisfaction guarantee. The kit is built for various environments, including street, drag, and track applications, drawing on years of research and testing to ensure compatibility and performance for the M42 engine platform.
