Cold Air Induction & air filter Kit 
NOTE: For manual cars only

Installing the cold air performance enhancement kit will make any standard 996 with factory mufflers sound as if you have added a very mild performance exhaust. This is perfect for any 996 owner that wants his car to sound slightly more aggressive than stock.

The cold air kit adds 1.5 liters of cold air by eliminating the plastic factory muffler in air pipe, this allows the engine to draw cold air across entire topside of air box (left and right rather than just from the right) Adds 0.42 seconds faster acceleration 3000-6000 RPM.

The cold air kit is made from 4 ply silicone tube - better flow from air box to throttle body.

No "Check engine" lights as you retain the factory MAF.

Please note this item fits MANUAL CARS ONLY Replacing Factory black hose 99611022157.

Kit Contains:
1 x Cold Air Hose
2 x Jubilee Clips
1 x Alloy Stopper plug

*Please add a K&N / BMC or DesignTek air filter with this kit as it is not included

About Hoses / Kits

Porsche Performance Hoses & Hose Kits - Engine Reliability & Cooling Upgrades

Engine Hoses and Hose Kits are responsible for transporting coolant, air, oil, and vacuum throughout the engine system. In high-performance or high-mileage Porsche vehicles, upgraded hoses are essential for maintaining pressure integrity, managing heat, and preventing leaks that can lead to serious engine damage.

Available from Design911, Porsche performance hose kits are engineered using high-quality materials such as reinforced rubber and silicone to deliver improved durability, heat resistance, and reliability in tuned, track-driven, and enthusiast-owned vehicles.

What Do Engine Hoses & Hose Kits Do?

Hoses and hose kits ensure the safe and efficient transfer of fluids and air within the engine system.

Core Functions:

  • Carry coolant, oil, air, and vacuum signals.
  • Maintain system pressure and flow integrity.
  • Support consistent engine cooling and lubrication.
  • Prevent leaks and fluid loss.
  • Enable reliable engine operation under load.

Proper hose function is critical for engine safety and performance.

Why Do Engine Hoses Fail?

Factory hoses are subject to heat, pressure, and chemical exposure, leading to degradation over time. Common failure causes include:

  • Rubber hardening and cracking due to heat cycles.
  • Oil contamination weakening hose material.
  • Swelling or collapse under increased pressure.
  • Age-related deterioration and fatigue.
  • Increased thermal load from tuned engines.

Failed hoses can result in coolant loss, overheating, oil leaks, or sudden engine failure.

Why Upgrade to Performance Hose Kits?

Performance hoses are designed to withstand higher temperatures and pressures.

Upgrade Benefits:

  • Improved resistance to heat, oil, and pressure.
  • Reinforced construction for long-term durability.
  • Reduced risk of leaks and hose collapse.
  • Ideal for tuned, track, and high-output engines.
  • Comprehensive kits simplify maintenance and upgrades.

Upgrading hoses improves reliability and protects critical engine systems.

Highlights

  • Porsche performance engine hoses and kits
  • Improved durability and heat resistance
  • Designed for tuned and high-performance engines
  • Reduces risk of leaks and hose failure
  • Ideal for preventative maintenance and rebuilds
