For fabricators and performance builders creating custom turbo piping, intercooler, or charge-air systems on the 6.7L Cummins, our IAT & MAF Sensor Bung Kit delivers a precision, professional-grade solution for relocating factory sensors. These CNC-machined bungs allow clean, accurate integration of the Intake Air Temperature (IAT) and Mass Air Flow / Manifold Absolute Pressure (MAF/MAP) sensors into aftermarket piping without compromising sensor function or engine management. We have these kits in aluminum, mild steel or stainless steel.
Precision CNC-machined from high-quality billet aluminum, mild steel, or stainless steel, each bung is engineered for strength, corrosion resistance, and a refined finished appearance. The kit includes stainless steel socket head screws for secure, long-lasting sensor retention. The contoured base features a carefully designed 4.5-inch radius, ensuring a seamless fit and excellent weldability on both 4-inch and 5-inch diameter tubing commonly used in performance turbo and intercooler piping.
When building a custom intake or turbo system, proper sensor placement is essential for accurate air metering, temperature compensation, and reliable engine operation. G&R Diesel’s billet bungs eliminate the guesswork and compromise of generic or poorly fitting alternatives, delivering a clean, OEM-quality integration that supports both performance and longevity. Proudly designed and manufactured in the USA, this kit reflects the same attention to detail found throughout the G&R Diesel product line.
This bung set is an essential component for any serious 6.7L Cummins custom fabrication project focused on both function and appearance.
