Step 1 - First, identify the ignition system your car has, most cars have a DIS (direct ignition system, shown). The HEI (high energy ignition) this ignition system has a distributor with cap and rotor. The COS system (coil over spark plug) which has no plug wires just ignition coils. Firmly grab a hold of the spark plug wire at the boot nearest the spark plug. Gently but firmly twist the boot to loosen the seal, now remove the spark plug wire.

Step 2 - Remove debris from the spark plug hole, (canned air works best) then use a socket wrench and spark plug socket to loosen and remove the spark plug (counter clockwise). Before you remove the spark plugs, mark the plug wires to identify their positions in the firing order, this will help to make sure they do not get mixed up. Always use a spark plug socket to remove the spark plugs. We use a spark plug socket because the inside of the socket is lined with rubber to help cushion the spark plug insulator, which is made of porcelain and can be easily cracked or broken removing or installing. If a spark plug insulator is cracked or broken the engine will misfire as the ignition spark will travel to the engine block (ground) instead of the spark plug gap (between the electrodes).

Before installing spark plugs always inspect the spark plug mounting hole threads, check for rust and debris, clean and lubricate as needed. If spark plug threads are damaged use a thread cleaner or tap loaded with grease to catch the metal chips that would go into the combustion chamber. Also use a can of compressed air with the long plastic extension the can comes with the can and insert into the spark plug hole down into the cylinder and blow excess partials out (cover your eyes from air

born debris) to help the removal of additional particles. When removing the spark plugs organize them according to their related cylinder. Next compare your spark plugs to those on the chart below for potential or present problems. Inspect spark plug condition

Step 3 - When reinstalling new plugs be sure the spark plugs you are installing are made for your car and engine size. Do not install spark plugs just because they fit, design issues can cause internal engine damage, example: if the spark plug electrode is to long it can damage the piston. Use a spark plug gapping tool to check the measurement between the electrodes, most spark plug gaps are between .035 and .045. This gap is important because it determines the amount of resistance used to "time" the ignition system. An incorrect spark plug gap will result in low power, poor mileage and possibly a check engine light notice. For the exact measurement for your car consult a car repair manual.

Remove the spark plug from the box or container and inspect the new plug for damage that could have occurred in shipping. A spark plug has a porcelain isolator that is fragile and can crack easily. Reinstall the spark plug and install the new spark plug wire. Most of the time a spark plug will come "pr

set" and ready to install. Continue the process until all spark plugs and spark plug wires have been replaced. Be sure to use OE (original equipment) parts for your car or truck to insure the proper performance from your vehicle.

Step 4 - When reinstalling the new spark plug make sure the sealing gasket is located on the threaded part of the spark plug, some spark plugs do not have a sealing ring, this is normal. Only tighten the spark plugs to "snug" and install a small portion of ant

seize grease to ensure proper installation. Save the old spark plug in the new spark plug boxes, store them for future reference. Once you have completed the spark plug change start the engine and inspect the running condition, it should be smooth with no extra noises. If your engine is running rough double check the spark plug wires to make sure one has not popped off or that the plug wires are in the right order.

Spark plug construction:

Spark plugs are one of the most misunderstood components of an engine. Numerous questions have surfaced over the years, leaving many people confused.

This guide was designed to assist the technician, hobbyist, or race mechanic in understanding, using, and troubleshooting spark plugs. The information contained in this guide applies to all types of internal combustion engines: two stroke engines, rotary engines, high performance/racing engines and street vehicles.

Spark plugs are the “window” into your engine (your only eyewitness to the combustion chamber), and can be used as a valuable diagnostic tool. Like a patient’s thermometer, the spark plug displays symptoms and conditions of the engine’s performance. The experienced tuner can analyze these symptoms to track down the root cause of many problems, or to determine air/fuel ratios.

Operation:

The plug is connected to the high voltage generated by an ignition coil or magneto. As the electrons flow from the coil, a voltage difference develops between the central electrode and side electrode. No current can flow because the fuel and air in the gap is an insulator, but as the voltage rises further, it begins to change the structure of the gases between the electrodes. Once the voltage exceeds the dielectric strength of the gases, the gases become ionized. The ionized gas becomes a conductor and allows electrons to flow across the gap. Spark plugs usually require voltage of 12,000–25,000 volts or more to 'fire' properly, although it can go up to 45,000 volts. They supply higher current during the discharge process resulting in a hotter and longer-duration spark.

As the current of electrons surges across the gap, it raises the temperature of the spark channel to 60,000 K. The intense heat in the spark channel causes the ionized gas to expand very quickly, like a small explosion. This is the 'click' heard when observing a spark, similar to lightning and thunder.

The heat and pressure force the gases to react with each other, and at the end of the spark event there should be a small ball of fire in the spark gap as the gases burn on their own. The size of this fireball or kernel depends on the exact composition of the mixture between the electrodes and the level of combustion chamber turbulence at the time of the spark. A small kernel will make the engine run as though the ignition timing was retarded, and a large one as though the timing was advanced.
