Application: 32 Valve 928 engines from 1987 thru 1995

More Air, More HP: The 928 Motorsports LLC custom intake runners are optimized for maximum performance from your 32v motor. They are a perfect fit to your heads after porting and large valves are fitted as per our CNC porting process here.

Quality Made: The intake runners are molded with a SLS process (Selective Laser Sintering) direct from the CAD file, for unrivaled accuracy and control. Two materials available, Glass Fiber (GF) reinforced, and Micro-Carbon Fiber (MCF) reinforced.

Adaptable: Our intake runners are designed to make your final intake system configuration a breeze. Mounting flange already provided for Individual Throttle Bodies (ITB's), or single or dual-plenum manifolds - whatever you like. And, because of the strength and location of our reinforcing fiber, you can have a large single plenum without concern that head movement during block expansion will damage it. Top flange already grooved to receive sealing O-rings (included).

Boosted or Naturally Aspirated: Tested up to 40 psi and at 220 deg Fahrenheit, these intake runners survived over 16,000 pressure cycles without any damage or deformity. They can handle your boosted or naturally-aspirated configuration!

Lightweight and Tough: The Nylon GF manifold is half the weight of an aluminum manifold the same size, and the Carbon Fiber version is lighter still! Takes weight off the important front-end of the car.

Finished Size: With these intake runners installed on 32v heads, here are your new specs:

• Intake runner length from plenum mounting flange to back of valve = 10.93"
• Intake runner diameter at plenum mounting flange = 2.25"
• Intake runner O-ring (supplied) outer diameter = 2.88"
• Height of the 928MS intake runner = 3.90" or 99.08mm
• Space envelope: Intake plenum flange to bottom of hood at front = 3.70"
• Space envelope: Intake plenum flange to bottom of hood at back = 4.70"
• Space envelope: Max plenum size is 20.6 Liters without extending outside the fuel rails.
