These stainless steel MAF bungs are machined in the USA from 304 stainless. They fit all Gen 4 LS and Gen 5 LT MAF sensors, cartridge style. Includes bolts.
The most common LS/LT Tube size is 4" as most throttle bodies are 4". But, if you have a larger tube for a supercharged or high hp N/A application, we have you covered there too! Just choose the intake tube size from the menu.
