TurboKraft’s high-efficiency long-neck intercooler package increases cooling, airflow, and performance for the 1978-1989 Porsche 930 Turbo.  
No modifications are necessary to the original factory air filter housing or air conditioning system.
Highest efficiency of any bolt-on 930 intercooler on the market:  
• Greatest charge air temperature drop
• Lowest backpressure

The "Long Neck" Style Intercooler:  A Long Neck intercooler’s outlet connects directly to the throttle body, eliminating the air bypass valve (aka “shuttle valve”).  This efficient intercooler configuration is used on the 930-S* and 964 Turbos.
* Note:  neither the 930-S/SE nor the Ruf BTR was fitted with a boost diverter/recirculation valve, reducing performance potential.

Inefficient Diverter/Recirculation Valve Systems:  These large, heavy assemblies are installed on 1978-89 930/911 Turbos between the intercooler and throttle body.  They diverting/recirculating boost pressure back to the intake side of the turbocharger when the throttle closes.  They are prone to failure, often causing drivability issues.  When the magnesium housing eventually wears out, it must be repaired or replaced at great expense.

Newer 1991-94 964 Turbos adopted long-neck intercoolers and compact, lightweight nylon recirculation valves, similar to the 944 Turbo’s.  This simplified layout accounts for much of the engine’s improved throttle response over previous 911 Turbos.

TurboKraft intercoolers use this superior configuration to improve drivability and enhancing boost response, allowing the turbocharger to spool up faster and remain engaged during gear shifts.

Finish Options:
These intercoolers are delivered in as-fabricated brushed aluminum finish unless you specify otherwise at the time of order.  
We offer two additional finish options: 
• Satin black coating ($200) is the most-requested optional finish, giving the intercooler a more OEM appearance.
• Polishing ($400) to a chrome-like finish is performed per order, and averages 3 weeks additional time. 
Please contact us for additional customization, such as EFI applications, e-throttle fitment, etc.
