Housing and 4 wire IAC idle control valve to allow Idle Speed Control to be fitted to many different engine types.
This is universal fitment and designed to mate with standard 19mm rubber hose which can then be plumbed into the intake air system

We have also fitted a reducer so that these can be used with 13mm hose.
Either leave in place for 13mm or remove to use 19mm

These kits are only suitable for vehicles with a Negative Earth electrical system.
If your vehicle is the older Positive Earth then you must convert the vehicle to Negative Earth before fitment.
Many older vehicles have already been converted but if you need to convert this is normally a simple process often cost free.

The full vehicle kits will normally be supplied with the ECU pre loaded with an initial start file.

This initial start file is simply provided as an aid for engine starting, it should not be considered a suitable final calibration for your engine.
You must be prepared to undertake further ECU calibration work to ensure the ECU files are tailored to your vehicle.
Failure to successfully complete the calibration process may lead to poor vehicle driveability or even damage to your engine.

Our Classic Fuel Injection Kits are custom built to order and to the customer general specification and as such are exempt from automatic return rights under Consumer Contract regulations.
By ordering this conversion kit you understand that further ECU calibration work will be required and the final results are outside of our control.
We cannot accept returns or claims arising from failure to successfully complete the calibration process.
