sooo i have been here for a while but everytime someone brings up spark plug gapping i am utterly clueless, what is it? how do i measure it?
HELP
thanks guys and girls
The spark plug gap information is marked on the "Catalyst" sticker under your hood. It is .058 - .060. Use a spark plug gapping tool.

If a spark-plug is not gas tight, leakage of gas past a spark-plug causes lowered gas pressure in the cylinder or damage to insulation from rising hot gases. The end of the spark gap is flush with the wall of the combustion chamber, depending on the reach of the plug, i.e. the length of the threaded part measured to the end of the body. If the reach is too short, the spark will be pocketed to cause difficult starting and misfiring at low speeds. If the reach is too long, the plug tip and the electrodes will project into the combustion chamber and become overheated to cause pinking, knocking, and, pre-ignition, resulting in loss of power. Protruding tip spark-plugs run cooler at high engine speeds and run hotter at low engine speeds because the insulator receives more heat but is cooled more by the incoming fuel. Too large a spark-plug gap can cause the sparking voltage of the plug to be too high overloading the secondary winding of the coil or preventing a spark from occurring. Too small a spark-plug gap causes incomplete burning of the mixture and the gap may become fouled. The wear, corrosion, and erosion of the plug electrodes cause gap growth. Rapid gap growth is caused by operation at too high a temperature that accelerates the burning of electrode material. Also, fuel containing tetra ethyl lead deposit lead oxides and sulfates to cause pitting of the central electrode. Corrosion deposits on the insulator may short circuit the spark-plug so that no spark occurs at the spark gap. Deposits of oil on the insulator and electrodes are caused by oil when the cylinder bores and piston rings are worn. Spark-plugs should be cleaned to produce a smooth, polished insulator surface each side of the gap. After cleaning the spark-plug, the spark gap must be checked with a feeler gauge
you can pick up a spark plug gapping tool at Auto Zone
Im a Xbox 360 fanboy...and damn proud of it!!

yup, its this one they sell
only 99 cents for it too
they have beefier spark plug gapping tools also which cost a little more but do more or less the same thing but I hear the cheap 99 cent gappers can damage platinum plugs, which is what come in the 2.4 stock.
I just paid my 3 bucks and got the better gapper. works the same either way though, just a matter of preference.
i never had a problem w/ mine, its pretty easy to use
