These are the contents of the kit as supplied by Mopar. The kit is available over the counter through Mopar dealers.

This is the way our 4.2L engine looked when prepped for installation of the Multiport Fuel-Injection kit, per Mopar's installation instructions.

Begin by installing the new distributor. Follow the instructions provided with the kit to set the timing. Install the nifty combination fuel-pump block-off plate/ignition-coil bracket where you removed the original fuel pump. Install the coil with the plug terminal toward the distributor.

Install the new crankshaft damper and the pickup-sensor bracket. The bracket bolts to the oil pan using three bolts removed during disassembly. Install the pickup sensor on the bracket with the bolt provided. There should be 0.020 to 0.060 inch of clearance between the sensor and the crankshaft damper. This clearance is critical to the operation of the system.

The kit includes a new thermostat housing, coolant sensor and 195-degree thermostat. The installation instructions note that it's important that the new thermostat be used for correct fuel system operation.

Install the new intake manifold. You will only be able to reinstall one of the power-steering-pump bracket bolts and you may have to trim the top lip off of the power-steering-pump bracket to make it fit the new manifold. Do not over-tighten the manifold bolts. Bolt torque is 23 lb-ft.

This is the new kick-down linkage mount at the transmission. After installation, you should set the adjustment by ensuring that the cable ratchets to the proper zero clearance. At this point you may reinstall the power-steering pump bracket and belts.
