If my memory is correct the Roush units are made by Borla.

The IAC PN is 205038

I can't see it but that location is next to the throttle bellcrank. They may be using a simple solenoid to step up the idle for A/C and power steering loads.

Best to give Roush a call. They are East Coast based. You are +6 on time zone to them.

Forgot "800" numbers don't work from overseas.

These should help.

IACs are stepper motors -not solenoids.

-- you need to know what Vintage of 427IR this is, as Roush has changed suppliers many times over the years.

Be prepared with your #SN and call mark yagelo -

Brilliant observation, and that's why I used a different nomenclature when referring to a different type part.

Not sure how your IAC is set up on the intake, but I just did an install on an 8 stack system and used a remote IAC valve that I mounted to the firewall. It was just a simple matter of running the vac line and the wiring to the remote IAC. This particular IAC stepper motor is the same that is used on a
Chevrolet LS-1 Engine so they are commonly available. I purchased my Remote IAC on E bay. Just a thought but from looking at that rousg set up it would be a pain pulling all the fuel rails just to change the IAC. Good luck
