Looking for a reliable gasket that restores a tight seal in your intake system and helps eliminate boost or air leaks? The MAHLE Intake Manifold Tube Gasket is designed to provide a secure OE-style seal between intake components, helping maintain proper airflow and engine efficiency. When intake gaskets wear out, leaks can develop, leading to reduced performance, a rough idle, poor fuel economy, or a loss of boost pressure. The G31916 solves this problem with a direct-fit replacement engineered to restore the integrity of the intake system. Ideal for maintenance or repair work, it helps ensure that air and fuel delivery remain properly balanced, allowing your engine to run smoothly and efficiently.

The MAHLE G31916 is manufactured to meet or exceed original equipment specifications, ensuring dependable sealing performance and accurate fitment. Its beaded steel construction concentrates sealing pressure along critical areas of the gasket, creating a durable, leak-resistant seal even under high temperatures, vibration, and pressure changes found in modern engines. Precision-stamped for proper alignment during installation, the gasket maintains consistent clamping force across mating surfaces for long-term durability.
