custom intake manifold / IDLE VALVE CONTROL

[srferreras]

Dear, is it possible to install the idle control valve in a custom intake manifold?

It depends on what you want to achieve and with what ecu. If your using a custom inlet with the stock ecu be a bit careful tune wise as the flow characteristics will be completely different. The stock idle up is water temperature controller via the waxostat under the throttle body. You would need to machine that setup off the manifold and then mount this remotely with air bypass and water lines etc. If your using an aftermarket ecu its easy as you can setup (ideally) a three wire idle speed control solenoid like the Bosch unit for example. They tune extremely well with a decent ecu. I use them all the time with Links. Just remotely mount the unit (or hang it under the inlet manifold on a bracket) with air lines to either side of the throttle butterfly. The Bosch ones are large enough to be used as an Antilag bypass too.
