MLS Engine Intake Manifold Gasket Seal 11617530703 For BMW N20 N26 N55 N63

Cost-effective  Engine Intake Manifold Gasket 11617530703 For BMW N20 N26 N55 N63

1. Product Overview

Technical Principle

The intake manifold gasket provides an airtight seal between the engine cylinder head and intake manifold. It prevents:

• Unmetered air leaks (causing lean mixture)

• Loss of intake vacuum (affecting brake booster operation)

• Contamination from external debris

BMW's precision engineering requires this gasket to maintain exact tolerances for optimal air/fuel mixture distribution across all cylinders.
