Air Cooled 3.6 IceBox Performance Cold Air Intake System
Elevate the heartbeat of your air-cooled legend with our "IceBox" Performance Cold Air Intake System. This system is specifically designed for "Hotrod/Outlaw" 964 Porsche 911 and a surgical upgrade for enthusiasts who chase analog response and power. By replacing the restrictive factory airbox, you unlock the signature flat-six growl that has defined Porsche’s racing heritage for decades.
The engineering focus of this system is centered on the High-Velocity Deck Lid Inlet. intake features an aggressive opening positioned directly beneath the deck lid grille. Unlike standard filters that breathe in the stagnant heat of the engine bay. This placement leverages the natural aerodynamics of the 911's silhouette, drawing in a constant stream of high-pressure, ambient air. This "ram-air" effect significantly reduces intake air temperatures (IATs), providing a dense oxygen charge that is crucial for maximizing combustion efficiency.
Heatsoak is the silent enemy of the air-cooled engine, especially during spirited canyon runs or track days. Our system acts as a thermal shield, ensuring that even when the sun is beating down on the tarmac, your engine is breathing air that is significantly cooler than the surrounding components. The result is a noticeable increase in throttle response and a more consistent power band. You’ll feel the difference the moment you tip into the accelerator, as the engine reacts with a newfound urgency and a crispness that factory setups simply cannot match.
We've designed this intake system to gulp in massive amounts of air. We’ve engineered bypass channels and drainage ports that divert rainwater and moisture away from the internal intake tract. Even if the clouds break during your drive, this critical safety feature prevents the risk of hydrolocking your engine and therefore giving you peace of mind that your flat-six is breathing only what it needs.
In keeping with the "Outlaw" spirit, this kit is fully customizable to match your specific build. Each system is a comprehensive "turn-key" solution, arriving with everything required for a seamless installation. This includes a high-flow washable air filter, OEM Porsche paper gasket (where applicable), mounting hardware, and unique add-ons designed to integrate perfectly with your 911’s iconic architecture. This product is designed to fit the following Porsche 911 models:
- 1989-1994 Porsche 911 (964) 3.6L EFIThe IceBox configuration you are purchasing fits:
- 964 Carrera C2/C4 3.6L with the factory air flow meter (AFM)Filter Elements included in the package are:
- Dryflow K&N Filter + Drycharger Water Repellent Sock
Important Fitment Notes and Disclaimers:
1) This system DOES NOT fit models equipped with a factory A/C condenser mounted to the deck lid. To achieve its superior cooling performance, this intake occupies the space directly under the rear grille. It is purpose-built for lightened, performance-oriented builds where thermal management and raw horsepower take priority over cabin cooling.2) Using 964 deck lid hinges is ABSOLUTELY REQUIRED if you own a G-body 911 with a 3.6L 964 motor swap.
3) We STRONGLY recommend you to purchase this kit with a water repellent air filter sock. This is a must-have item to protect your engine from hydro locking in case of heavy rain or carwash. Please make sure to choose the right air filter combination in order to receive this crucial part.4) We are NOT a K&N Engineering, Inc. distributor or affiliate. Please contact the manufacturer representatives directly for questions or concerns regarding the air filter element or the water repellent sock included in this kit.5) We use the following couriers:
