079133074B Intake Manifold Gasket - wholesale prices

The 079133074B is an intake manifold gasket commonly used in engines from Audi, Volkswagen (VW), and related brands. Below is a detailed overview:

1. Function
The intake manifold gasket serves as a seal between the intake manifold and the engine cylinder head. Its primary roles include:

• Preventing air, fuel, and exhaust leaks in the intake system.
• Ensuring proper air-fuel mixture delivery to the engine cylinders.
• Maintaining engine performance and preventing vacuum loss.

2. Material
Typically made from high-quality materials like rubber, silicone, or composite materials to withstand high temperatures and pressure within the engine.

3. Compatibility
This gasket is commonly used in high-performance engines, such as those in Audi and VW models equipped with V6 or V8 engines. Compatibility should be confirmed using the vehicle’s VIN or engine code.

4. Symptoms of Failure
A failing or damaged intake manifold gasket can cause the following problems:

• Engine misfires or rough idling.
• Reduced engine power or poor acceleration.
• Coolant leaks near the intake manifold area.
• Check Engine Light illumination with relevant error codes (e.g., P0171 or P0174 for lean conditions).
• Hissing noise due to vacuum leaks.

5. Replacement Tips

• Ensure the intake manifold and cylinder head surfaces are clean and free from old gasket residue before installation.
• Use the correct torque specifications and tightening sequence for the manifold bolts to avoid warping.
• Inspect the intake manifold for cracks or warping during replacement, as these issues can mimic gasket failure symptoms.
• Consider replacing associated components like O-rings or seals for a comprehensive repair.

Proper installation and maintenance of the 079133074B intake manifold gasket are essential for optimal engine performance and longevity.
