Magnuson Inlet Bellows for 1999-2013 GM Trucks & SUVs

Replace your worn, cracked, or damaged Magnuson Supercharger Inlet Bellows with this direct-fit replacement designed for 1999-2013 GM trucks and SUVs equipped with Magnuson supercharger systems. A damaged inlet bellows can allow unmetered air to enter the intake system, causing vacuum leaks, lean fuel conditions, rough idle, poor drivability, and reduced supercharger performance.

This Magnuson Supercharger Inlet Bellows is commonly used on GM applications equipped with MP112, MP122, TVS1900, and TVS2300 Magnuson superchargers. Designed to withstand engine movement, heat cycles, and boost pressure, this replacement bellows helps maintain a proper seal between the intake system and supercharger inlet.

Over time, factory bellows can become brittle and develop cracks that negatively affect airflow and engine performance. Replacing a damaged bellows is an important part of maintaining the reliability and efficiency of your Magnuson supercharger system.

Why Replace Your Magnuson Inlet Bellows?

The inlet bellows is an important component of your Magnuson supercharger system because it provides a sealed connection between the air intake assembly and the supercharger inlet. As GM trucks and SUVs accumulate mileage, the rubber material can become brittle from engine heat, oil vapors, and repeated boost cycles. Small cracks or tears may develop that allow unmetered air to enter the engine, affecting fuel trims and overall performance.

Replacing a damaged Magnuson inlet bellows can help restore proper airflow, improve idle quality, and eliminate vacuum leaks that may trigger diagnostic trouble codes. This replacement bellows is an excellent choice for routine maintenance, supercharger servicing, or whenever the intake system is being inspected for leaks.

Whether you drive a Chevrolet Silverado, GMC Sierra, Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, or Cadillac Escalade equipped with a Magnuson supercharger, maintaining a properly sealed intake system is essential for reliable performance and consistent boost pressure. Installing a new Magnuson inlet bellows helps ensure your supercharger system operates as intended while protecting engine performance for years to come.

While servicing your Magnuson supercharger, it is also a good time to inspect the coupler, supercharger oil, bearings, and drive belt. Replacing worn service components together can help maintain reliability and performance.
