Allow the engine to cool completely before attempting the ignition tune up. You can use this time to inspect and gap the new spark plugs. There are different types of gappers for certain plugs so make sure you ask the PartsPro at your local Partsource for the correct spark plug gap tool when you purchase your new plugs. The PartsPro will also know the specific gap for the type of plug you are buying as well.

Depending on which angle you're working from cover the front of the vehicle or the fender to prevent damaged to paint. Damaged can be caused from the snaps or buttons on your clothes. For safety, remember to disconnect the ground cable on the battery.

Remember: Only remove one plug at a time to ensure proper placement of the wires.
Remove the spark plug wire. Only pull on the boot end, never on the wire. Use a left and right twisting motion to free the wire boot from the spark plug. Use a spark plug boot puller tool to avoid damaging the wire.

TIP: If you have an air compressor, use it to blow any dirt from the spark plug area. A common bicycle pump will do the trick as well. We do not want any dirt falling into the cylinder upon removal of the spark plug.

Place the spark plug socket over the spark plug and remove by turning in a counterclockwise direction.

Now you are ready to install the new plug which we gapped while waiting for the engine to cool down.
Apply anti-seize to the threads of the spark plug. Apply dielectric grease to the ceramic part of the spark plug, to seal the plug to the wire boot.
Thread the plug into the hole tightening as much as possible by hand. Some vehicles come with aluminum cylinder heads which can strip very easily if we are not careful.
Use a torque wrench to tighten to specified torque. Torque specifications can be found using Mitchell onDemand at your local PartSource.

TIP: If you do not have a torque wrench, a good rule of thumb is to bring the plug up snug (finger tight) then give it between one-fourth to one-half turn more. For tapered seat plugs give it one-sixteen turn more.

Remember: Over tightening the plugs can change the gap and cause other damage. Low torque may cause the plug to overheat and possibly cause preignition.

Place the wire back onto the spark plug by using the same twisting motion we used to take it off. You can do this by hand, the tool is only required for taking the spark plug wire off. Repeat the steps above for the rest of the spark plugs, making sure they are done one at a time so we do not mix up the wires.

Apply dielectric grease to contact points on the new distributor cap and rotor.
Disconnect the battery ground cable.
Remove the old distributor cap with the wires attached. Depending on the vehicle your distributor cap is either held down by screws or clips. For specific instructions for your make and model refer to Mitchell onDemand at your local PartSource.
Remove one wire at a time from the old distributor cap, pull only on the boot end never on the wire.
Install the wire on the new distributor cap in the same position. We want to do this one at a time so we do not mix up the firing order.

TIP: Not all distributor caps have terminal ends that the wires go over, on some vehicles the spark plug wire is held inside the cap by a wire retainer. When removing the wires on this style of distributor cap, use a pair of pliers to compress the wire retaining clips inside the distributor cap before pulling the wires out.
Remove the old distributor rotor, it will simply pull off. If the rotor does not pull off, use a twisting pulling motion until it comes free. Do not try to pry the rotor off with a screwdriver you may cause damage to the distributor.
Install the new distributor rotor by lining up the notch in the distributor shaft with the notch in the rotor.
Apply anti-seize to the distributor hold down screws.
Install the new distributor cap with wires in the same position as the old one.

Check the new wires to see if they come with dielectric grease applied already. If they don't make sure you have some dielectric grease to apply to the spark plug terminal. Disconnect the battery ground cable.
Remove one wire at a time so we do not mix up the firing order. Only pull on the boot end, never on the wire. Use a left and right twisting motion to free the wire boot from the spark plug.
Match the old wire to the new wire. The wires come in different lengths so make sure you match up the right length.
Before you install the wire on the spark plug terminal make sure to apply some dielectric grease to the wire if it did not come preapplied inside the spark plug wire boot.
Apply dielectric grease to the distributor cap contacts. Depending on your vehicle apply to the distributor cap terminals or the wire retainers inside the cap.
Attach the new plug wire to the spark plug using a twisting motion on the boot until it's seated on the spark plug.
Repeat the steps above for the remaining plug wires.
