- Porsche 971.1 Panamera 4S Diesel V8 4.0L 4WD (422 Hp) 2017-18
- Porsche 971.1 Panamera 4S Diesel 4.0L Twin-Turbo V8 Sport Turismo 2017-18
The genuine Porsche intake manifold gasket is a factory-specified sealing component used on the 4.0 L diesel version of the Porsche Panamera (971 generation). It sits between the intake manifold and the cylinder head, providing a durable seal that prevents air and charge-pressure leaks in the induction system.
Sold each.
Fits:
Porsche 971.1 Panamera 4.0L Diesel 05/2016 - 12/2020 TDI CR
Diagram ref no 2 and 9
• Position on Vehicle: Between the intake manifold and the cylinder head (intake side) on the engine block.
• Applications: Ideal for replacement when the intake manifold is removed or during maintenance/intervention where the original gasket may have been disturbed, degraded, or if the engine exhibits induction leak symptoms (like rough idle, turbo boost drop or check engine lamp).
A properly functioning intake-manifold gasket is key to maintaining correct air intake, charge-pressure retention and combustion efficiency. A leaking gasket can lead to poor engine running, reduced boost, increased emissions or even turbocharger strain. Replacing it with the genuine product ensures factory-correct sealing, protects your engine’s performance potential and helps preserve value.
When to replace:
• Intake manifold removed for service or repair.
• Signs of induction leakage: unstable idle, boost pressure dropped, check engine faults.
• Age-related wear, material fatigue or previously reuse of the old gasket.
• Planning long-term reliability or restoring to original specification.

Air Inlet Engine Gaskets – Precision Sealing for Optimal Porsche Performance
Air inlet engine gaskets are crucial sealing components within your Porsche’s intake system. They ensure an airtight connection between the intake manifold, throttle body, and other air passages, preventing unmetered air from entering the engine. By maintaining proper air pressure and flow, these gaskets help your Porsche deliver smooth performance, efficient combustion, and consistent power output.
At Design911, we supply a complete selection of genuine and high-quality air inlet gaskets for various Porsche models, including 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each gasket is designed for precise fitment, high heat resistance, and superior durability — ensuring reliable performance and long-lasting sealing under all driving conditions.
What Do Air Inlet Engine Gaskets Do?
Air inlet gaskets serve as a critical barrier that ensures
only properly metered air enters your Porsche’s engine. Their functions
include:
- Sealing
joints between intake components to prevent air leaks.
- Maintaining
correct air-fuel ratios for efficient combustion.
- Preventing
contamination from oil, dust, and debris.
- Ensuring stable engine idle and performance by regulating airflow integrity.
A high-quality gasket keeps your Porsche’s intake system perfectly balanced, contributing to smooth throttle response, better fuel efficiency, and reliable power delivery.
Why Do Air Inlet Engine Gaskets Fail?
Exposure to extreme heat, pressure, and vibration gradually
wears down air inlet gaskets. Over time, they can lose elasticity and sealing
capability. Common causes of failure include:
- Thermal
expansion and contraction causing cracks or deformation.
- Material
fatigue from continuous heat cycling.
- Oil
or coolant contamination degrading gasket integrity.
- Improper
installation or over-torquing during servicing.
- Age-related wear and drying of gasket material.
Symptoms of a failing air inlet gasket include rough idle, vacuum leaks, hissing noises, poor fuel economy, or a check engine light related to air-fuel imbalance.
Why Replace a Faulty Air Inlet Engine Gasket?
A worn or leaking air inlet gasket can allow unmetered air into the engine, disrupting combustion and reducing performance. Replacing it restores proper air sealing, improving efficiency and reliability while preventing potential damage to intake components.
Benefits of replacement include:
- Restored airtight sealing for optimal engine performance.
- Smoother idle and improved throttle response.
- Enhanced fuel efficiency and reduced emissions.
- Long-term reliability with manufacturer-quality materials.
All gaskets from Design911 are made from premium-grade composites or multi-layer materials, designed to withstand heat, pressure, and chemical exposure — ensuring consistent sealing and performance for every Porsche model.
