Upgrade or replace the high-pressure charge-air hose on your Porsche 911 (997-series) Turbo/GT2 with these genuine OEM components. The left/upper hose is Part 99711064403 and the right/upper one is Part 99711064503. These hoses carry compressed, cooled air from the intercooler outlet to the Y-pipe/intake manifold, ensuring your engine receives the designed boost volume. If you’ve experienced loss of power, hear hissing under load, or notice boost irregularities, these direct-fit Porsche parts restore the integrity of your forced induction system.

What This Product Does:
- These hoses/pipes are part of the charge-air system (after the turbocharger) and connect components like the turbo(s) → intercooler(s) → intake manifold(s). They carry compressed air at elevated pressure and temperature.
- The purpose: When the turbo compresses intake air, it gets hot; after the intercooler it is cooled, then routed via these hoses to the engine. Secure, leak-free hoses ensure the engine receives correct volume and pressure of air.
- If the hose is compromised (e.g., leak, crack, split), then boost pressure drops, the engine may lose power, run richer/leaner, trigger fault codes, and the car’s performance degrades.
Symptoms & Signs You Might Need Replacement:
- Loss of boost / reduced power: If you’re not getting full boost, or turbo seems slower to build, a leak in this hose is a common fault.
- Hissing or whistling noise during acceleration (especially under load) — indicates air escaping from pressure side of the system.
- Check Engine Light / fault codes relating to boost pressure, turbocharger performance or intake air pressure.
- Visible damage or wear: cracks, splits, swelling, hose soft spots, or hose clamps loose or missing.
- Oil or dirt buildup around the hose connection points — may suggest a leaking pressure hose has allowed contaminants in.
- Restores correct performance: For a turbocharged 911, accurate boost pressure and charge-air delivery are critical for performance. A failing hose disrupts that.
- Prevents further damage: A leaking charge air hose can lead to incorrect air/fuel mixture, cause lean conditions, increase exhaust temps, or stress the turbo/intercooler system.
- Safety & drivability: A compromised hose might fail catastrophically under boost, leading to a sudden loss of power, which could be dangerous in certain driving conditions.

In turbocharged Porsche engines, maintaining a fully sealed charge air system is essential for performance, efficiency and reliability. Even a small failure in a sealing component can result in boost leaks, reduced power and engine management issues.
What This Seal Does
The seal sits between the intercooler and the throttle body, creating a secure and airtight connection.
It helps:
• Maintain correct turbo boost pressure
• Prevent air leaks within the intake system
• Ensure efficient airflow into the engine
• Support proper combustion and engine performance
• Maintain consistent throttle response
A properly functioning seal is essential for the correct operation of the turbo system.
Why Throttle Body Seals Fail
Sealing components are exposed to heat, pressure and constant airflow, which can lead to degradation over time.
Common causes of failure include:
- Heat exposure - High temperatures from compressed air can harden or deform the seal.
- Pressure stress - Continuous boost pressure can wear sealing surfaces.
- Material ageing - Over time, rubber or sealing materials lose elasticity.
- Removal and refitting - Seals can become damaged or deformed during servicing.
Symptoms of a Failing Seal
• Loss of turbo boost pressure
• Reduced engine performance
• Hissing noise from intake area
• Engine warning lights related to boost or airflow
• Poor throttle response
• Increased fuel consumption
Replacing a worn seal restores system integrity and prevents further performance issues.
Why You May Need to Replace This Seal
- Prevent Boost Leaks - A new seal ensures airtight connections within the intake system.
- Restore Engine Performance - Maintains proper airflow and boost pressure for optimal power delivery.
- Essential During Intercooler or Throttle Body Service - Recommended to replace whenever components are removed.
- Low-Cost Preventative Maintenance - A small component that plays a big role in turbo system efficiency.

A turbocharger uses energy from the engine's exhaust gases to drive a turbine connected to a compressor wheel. The compressor increases the pressure and quantity of air supplied to the engine, allowing the engine-management system to deliver the intended levels of power, torque and response.
Turbochargers operate at extremely high rotational speeds and temperatures and depend on clean lubrication, correct cooling, unrestricted intake and exhaust flow, and properly functioning boost-control systems. Bearing wear, oil-supply problems, foreign-object damage, excessive temperatures or control faults can eventually cause turbocharger deterioration or complete failure.
Replacing a confirmed faulty turbocharger helps restore correct boost pressure and engine performance while reducing the risk of further damage to associated intake, exhaust and engine components.
What This Product Does:
The turbocharger increases the amount of air supplied to the engine by using energy that would otherwise leave through the exhaust.
Exhaust gases spin the turbine wheel. A shaft connects this turbine to a compressor wheel on the intake side.
As the compressor rotates, it compresses incoming air and supplies it to the engine under pressure.
This helps:
- Generate the required boost pressure
- Increase available intake airflow
- Increase engine power and torque
- Improve acceleration and engine response
- Maintain the intended factory performance
- Make effective use of exhaust-gas energy
The turbocharger works together with the intake, intercooling, exhaust, lubrication, cooling and electronic engine-management systems.
Symptoms Of Wear Or Failure:
Common symptoms associated with turbocharger deterioration can include:
- Loss of engine power
- Reduced boost pressure
- Slow boost response
- Poor acceleration
- Inconsistent power delivery
- Engine-management warning light
- Underboost or overboost fault codes
- Limp or reduced-power mode
- Increased engine oil consumption
- Blue or grey exhaust smoke
- Excessive oil in intake pipework
- Whining or siren-like noises
- Grinding or scraping noises
- Excessive turbocharger shaft play
- Damaged compressor or turbine blades
- Abnormal boost fluctuations
These symptoms can also be caused by faults elsewhere in the engine or boost system. Proper diagnosis should therefore be carried out before replacing the turbocharger.
Why Replacement Matters:
Replacing a confirmed worn or damaged turbocharger helps restore the intended operation of the forced-induction system.
A correctly functioning replacement can help:
- Restore boost pressure
- Restore engine power
- Restore torque
- Improve acceleration
- Restore throttle response
- Correct turbocharger-related mechanical noise
- Address oil leakage caused by internal turbo wear
- Restore reliable forced-induction operation
- Support correct engine-management operation
- Reduce the risk of secondary component damage
A severely damaged turbocharger should not remain in service.
