Which way do you turn to get spark plugs out?

Place the socket around the spark plug and turn the socket counterclockwise. The spark plug should unscrew easily. If you are having problems removing a spark plug that is too tight, stop before you break it off. You can put a bit of dedicated penetrating oil to help loosen it.

Why are spark plugs side gapped in racing?

Side gapping spark plugs has been use in racing for years to increase horsepower by unshrouding the spark thus allowing the flame created to propagate faster resulting in a more complete burning of the fuel/air mix. Many manufacturers offer plugs deemed racing plugs that are side gapped but at inflated costs.

How can I save money on spark plugs?

By doing it yourself you can use a cheap .99 cent plug to save money and increase horsepower. Using a dremel with a cutoff wheel or a hacksaw you will need to cut the ground electrode even with the edge of the center electrode.

Why are spark plugs with fine wire better?

“Spark plugs with fine wire center and/or ground electrodes operate better for two reasons. First, a smaller center electrode requires less voltage to jump the gap. This means fewer misfires, which will be seen in higher mileage and more horsepower. The second reason is smaller center and ground electrodes reduce quenching.”

What do you use to cut spark plugs?

Using a dremel with a cutoff wheel or a hacksaw you will need to cut the ground electrode even with the edge of the center electrode. You need to be careful not to hit the center electrode or the porcelain. Next you will need to use a file to remove any burrs left from cutting the ground electrode.

How do you change a spark plug in a car?

Apply a small amount of plug wire grease to the plug wire boot (or COP boot) and re-install each plug wire or ignition coil. Be sure and connect the plug wires to the appropriate spark plug for each engine cylinder (refer to a firing order diagram if necessary). Re-install the coil hold down bolt (s).

What’s the rule of thumb for tightening spark plugs?

Here’s the rule of thumb when tightening spark plugs. With tapperd seat sparkplugs turn the spark plugs 1/8 turn to tighten them. With gasketed seat spark plugs turn the spark plugs 1/4 turn to tighten them. If you followed these rules you’re okay. Aye, 1/4…my bad. I don’t even think about it any more, I just do it.

Where can I get a torque wrench for a spark plug?

Check your owner’s manual or the spark plug box. You will need a torque wrench, available at your local AutoZone. Apply a small amount of plug wire grease to the plug wire boot (or COP boot) and re-install each plug wire or ignition coil.
