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.
