Description

Custom Idle Air Control Body for use with Jeep 4.0l IAC Valve

'DarkStar' Custom IAC Body for Jeep Stepper Motor Idle Air Controllers

Custom machined IAC body for installing a IAC valve from a Jeep 4.0l motor, perfect for idle control with the MegaSquirt-II! Everything in the pictures is included, just add the IAC valve with o-ring and wire it up! 4 Mounting holes on the bottom/side depending on how you mount it with screws included. You should be able to find an existing bracket or spot on the firewall to bolt it to. Note that the current version has replaced the brass hose barbs with lighter, corrosion proof nylon instead.

This valve body flows best if you plumb it so that pre-throttle air enters below the valve and exits above the valve to the manifold. This will give you a wider range of idle speed adjustment.


More Information:

Dimensions are: 2.25"x 2.25" x 1.75" OR 57mm x 57mm x 44mm

Part Numbers for Compatible Valves (provided by DarkStar):

  • Niehoff Part# 21774 (this is what was used in all testing)

  • Wells AC320

    The Standard AC151 and Borg Warner 21774 have the smaller pintle and may work on larger engines but are not guaranteed. This IAC body was designed to work with the "large pintle" version, where the pintle measures 0.490" to 0.550" at the largest point.

 

OEM Application of this valve: 1991-1997 Jeep Cherokee, Grand Cherokee, Wrangler and Comanche (including submodels) w/ 4.0L Inline 6 VIN S 

 

Hose barbs are for 7/16" (about 9.5mm) ID hose.
