Air Intake Boot
Fits:
Porsche 964 - 1989 to 1994
Porsche 993 - 1994 to 1998
Silverlake Projects presents a complete intake system for air-cooled Porsche 964/993 engines equipped with ITBs (Individual Throttle Bodies), designed for maximum performance and efficiency.
The intake system includes:
- 2 x GT3-style intake manifolds in carbon fiber
- Glass-reinforced thermoplastic intake T-tube for air filter connection
- Resonance flap or resonance flap delete tube in glass-reinforced thermoplastic, complete with vacuum actuator
- 6 x high-temperature silicone couplers for manifold-to-runner connections
- 4 x high-temperature silicone couplers for manifold-to-T/resonance flap connections
- TMAP sensor for accurate manifold pressure readings
- All mounting fasteners in lightweight titanium alloy
- Vacuum reservoir for optimal pressure management
Weighing just 4.5 kg (9.9 lbs), this system is significantly lighter than the stock 964 intake, which weighs 11.5 kg (25.3 lbs).
Why choose our system?
- 50% lighter than stock: A combination of carbon fiber, thermoplastics, and titanium results in a remarkably light system.
- Fuel rail precision mounting: Direct mounting to the runner ensures perfect injector press fit.
- Superior heat insulation: CNC-machined PTFE inserts between the cylinder head and runner offer exceptional heat protection, especially in idle or street driving conditions.
- Perfect sealing: Custom nitrile O-rings between the runner and cylinder head, as well as the intake T and throttle body, guarantee a secure, leak-free fit.
- Premium silicone sleeves: Silverlake’s precision-molded OEM+ silicone sleeves provide superior temperature resistance and ensure a flawless fit with all components, delivering better airflow and an unmatched look.
- Titanium fasteners: Tin-coated titanium alloy hardware not only reduces weight but also enhances the system’s aesthetic appeal.
This intake system is built for those seeking the ultimate performance, weight savings, and durability for their Porsche 964/993 engine.

Air Intake Boots – Durable Airflow Connectors for Porsche Engines
Air intake boots are essential components of your Porsche’s intake system, connecting the air filter housing to the throttle body or intake manifold. These flexible connectors ensure that only clean, filtered air reaches the engine, maintaining efficient combustion and smooth performance. A high-quality air intake boot helps prevent unmetered air leaks that can lead to poor drivability, reduced performance, or increased emissions.
At Design911, we stock a comprehensive selection of genuine and high-quality air intake boots for numerous Porsche models like 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each boot is built from durable, heat-resistant materials and designed for an exact fit to provide airtight sealing and long-lasting reliability.
What Do Air Intake Boots Do?
Air intake boots form a critical part of the engine’s air
management system. They:
- Deliver
clean, filtered air from the intake system to the engine.
- Maintain
airtight sealing for accurate air-fuel ratio control.
- Reduce
turbulence to improve engine efficiency and throttle response.
- Protect sensors like the MAF (Mass Air Flow) sensor from contaminants.
Properly functioning intake boots ensure stable idle, consistent power delivery, and efficient fuel combustion — key to maintaining Porsche’s renowned performance and responsiveness.
Why Do Air Intake Boots Fail?
Over time, air intake boots endure constant exposure to
heat, pressure, and engine vibration. Common causes of failure include:
- Cracking
or splitting from heat and age.
- Loose
clamps or fittings leading to air leaks.
- Oil
contamination softening or degrading the rubber.
- Vacuum
leaks causing unmetered air to enter the system.
- Improper installation or wear due to engine movement.
Symptoms of a failing air intake boot include rough idling, check engine light warnings, engine misfires, or loss of acceleration performance.
Why Replace a Damaged Air Intake Boot?
A cracked or leaking intake boot can allow unfiltered air into the engine, upsetting the air-fuel balance and potentially causing long-term engine damage. Replacing the boot restores correct airflow and maintains efficient engine operation.
Benefits of replacement include:
- Restored air-fuel ratio for improved performance.
- Reduced risk of engine misfires and stalling.
- Enhanced throttle response and smooth acceleration.
- Long-term reliability with manufacturer-quality construction.
All air intake boots available from Design911 are made from high-grade rubber or silicone compounds, ensuring superior resistance to heat, oil, and vibration for dependable performance in every driving condition.
