Information
Air Pressure Hose.
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.

Information
Introducing our TTE600 Turbochargers for the 991 CARRERA 3.0 for the ultimate blend of power, response, and Plug&play ease of fitment. Our first upgrade step utilizing the original turbochargers for greater flow and power. TTE600 Performance turbochargers can and do make over 600PS with the right software at low boost with ease, yet offer only a little loss in response but offer a big step too more power. These really do offer a great balance of high power and fast response.
Engineered & Enhanced:
TTE600 Turbochargers start life as Genuine OE units. Engineered and enhanced using mostly BorgWarner components. TTE600 uses RS4 compressor covers that we CNC machine in house to an optimum clearance to allow fitment and maintain the efficiency of a larger more advanced billet TTE compressor wheels. The compressor wheel design features promote greater airflow using a low inertia wheel that performs like a wheel of even greater size and mass. Extended tip technology enables the user to have faster spool-up at lower engine speeds while providing high boost with less heat for the powerful top-end performance.
Turbine and shaft are original BorgWarner items bigger in size than the original for more power.
Special profile 360 deg high-performance motorsport journal bearing is fitted as standard, to remain durable at higher loads with no loss in transient response.
Actuators used are OE units fitted for trouble-free operation.
Equilibrium:
Precisely balancing our turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on application at up to 250,000 RPM in multiple planes using our in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with serial numbered balance test result document.
Product Highlights:
• Original BWTS turbocharger as base part
• TTE Billet Milled compressor 6+6 BLADE
• BWTS High-Flow Turbine
• Plug and Play installation
• 600 PS Capable
• Proven TheTurboEngineers quality
• Single parts finely balanced then components assembled and core high-speed VSR balanced
• Supplied with a balance test result document
• Made in Germany
