6 Port Air Control Valve Kit

jenvey

A kit of parts to adapt from a 19mm pipe to supply idle air to a set of 3 twin throttle bodies or any six port manifold with suitable tapping's.

When incorporating an air bypass valve into an induction system with individual butterflies, it is important to ensure that the air is evenly distributed between cylinders.
To achieve even distribution we recommend that a suitable distribution manifold is placed between the
bypass valve and the inlet tracts such that the tubes to each cylinder are all of the same length.
The preferred position to introduce the air, particularly if the injector is not aimed directly at the back of the inlet valve, is near to the injector, thus providing optimum conditions for air/fuel mixing.

Positioning the extra air inlet near the bottom of the tract should be avoided to prevent fuel flow-back under certain
conditions.

Jenvey heritage triple IDA3 throttle body set

jenvey

IDA3 is the Weber carburetor Porsche fitted to the 911 from 1966 to 1972
These Jenvey throttle bodies are manufactured to look like the original ID3 keeping the engine bay looking period correct

Sold as a pair

Available in 42mm or 45mm Ø

The new Heritage IDA3 throttle bodies are a natural progression to the exceptionally successful DCOE Heritage Throttle bodies released in 2017. They boast all the plus points associated with Individual Throttle Bodies (ITBs) kits, yet manage to marry these with the subtle, understated looks of a period carburetor induction set-up – ensuring that it won't look out of place in the engine bays of classic and retro vehicles.

The advantages of modern, electronic fuel injected intake systems are simply too hard (and too numerous) to ignore, with some of the key facets being a reliable, unbroken flow of air, extremely accurate control via advanced standalone ECUs, easy starting in all seasons, and of course, more power and economy. The sole downside on a classic installation, up until now, has always been the aesthetic – something that the Jenvey Heritage Throttle Body solves with its retrospective exterior design and exquisite engineering.

The Jenvey Heritage IDA3 throttle bodies are available in 42mm and 45mm. All bodies include injectors, throttle position sensor (tps) and integrated fuel rail

All Jenvey heritage products are compatible with E10 fuel (and upto E20 ). Moving to fuel injection will allow for easier air fuel ratio compensation and adjustment for any change in the future.

Jenvey idle control valve

jenvey

A small electronic idle control valve allowing control of idle air flow and idle speed.

Set-up:
The windings are brought out to pins 1&4 for the 2 ends of the first winding and 2&3 for the second winding - each 55 ohms.

Polarity is best determined by trying - if it moves the wrong way EITHER swap pins 1&4 OR swap 2&3 with each other.

About Jenvey Throttle Bodies

Jenvey Throttle Bodies – Precision Airflow, Motorsport Response & Advanced Engine Tuning

Jenvey throttle bodies are renowned for delivering exceptional throttle response, increased airflow efficiency and refined drivability, making them a leading choice for Porsche engine rebuilds and performance conversions. Designed using motorsport engineering principles, Jenvey’s individual throttle body (ITB) systems improve cylinder-to-cylinder airflow balance, enhance mid-range torque and significantly boost high-RPM breathing.

Ideal for naturally aspirated performance builds, standalone ECU conversions and motorsport applications, Jenvey throttle bodies offer the accuracy, adjustability and build quality needed to achieve precise engine tuning and optimised performance.

What Jenvey Throttle Bodies Do

Jenvey ITB systems provide a range of performance benefits:

  • Improve throttle response by reducing intake volume and increasing airflow velocity
  • Deliver balanced airflow to each cylinder for smoother, more consistent combustion
  • Enhance high-RPM power through individual, unrestricted air passages
  • Improve drivability with ultra-precise throttle modulation
  • Enable advanced tuning with standalone engine management
  • Support performance camshafts and high-compression builds with increased airflow capability
  • Produce iconic induction sound, popular with motorsport and track-day enthusiasts

The result is a more responsive engine with sharper acceleration and cleaner power delivery.

Why Throttle Bodies Fail Over Time

Even high-quality throttle systems experience wear, particularly in demanding environments such as track use, heat cycles and extensive mileage. Common causes of throttle body failure include:

  • Worn throttle shafts or bearings, creating air leaks
  • Carbon buildup restricting plate movement
  • Cracked or distorted housings from heat cycling
  • Vacuum leaks due to degraded seals or misalignment
  • Linkage wear causing uneven throttle opening
  • Contaminated airflow, affecting tuning accuracy
  • Electronic actuator faults (on drive-by-wire systems)

Failure symptoms often include: rough idle, hesitation, flat spots, uneven cylinder behaviour, or difficulty synchronising throttle banks.

Why You Should Replace or Upgrade to Jenvey Throttle Bodies

Upgrading to precision-engineered Jenvey throttle bodies, designed to surpass original induction performance, delivers significant benefits:

  • Sharper and more immediate throttle response
  • Increased airflow and improved volumetric efficiency
  • More accurate and stable tuning control
  • Improved peak power and torque gains
  • Greater compatibility with custom cam profiles and standalone ECUs
  • Enhanced reliability using motorsport-proven materials
  • Reduced intake restriction and smoother airflow characteristics

For any rebuild or performance-focused Porsche engine, Jenvey ITBs provide a major improvement in responsiveness, tuning capability and overall performance.
