As an example, when you raise compression or add forced induction a turbo system, nitrous or supercharger kit you must reduce the gap about. However, when you add a high power ignition system such as those offered by MSD, Crane, Nology you can open the gap from. Too small of a gap may give too weak of a spark to complete the combustion process within the engine; too wide of a gap can lead to the spark plug not firing correctly, causing misfires at high speeds.

They recommend not gapping them because the irridium center electrode is more brittle than most metals and can be fractured or broken.
They should be preset. Gap used to matter more when we had weak ignition systems. The recommended gap for a spark plug is not a precise figure, but simply the midpoint of a preferred range.
It has blades of different widths that you can use to measure as well as adjust the gaps. NGK spark plugs should be clean when straight out of the box. However, if you wish to use a plug that has been in the car, you should clean it with a cloth. It might have some soot at the contact points, and this can interfere with the reading. If the dirt does not come off with ease, you can use quick-drying alcohol for this process.
If this does not help, think of getting new plugs. You can now measure the gaps using the appropriate tool. You may or may not need to adjust the gap. Where the tool passes through the gap and does not touch the electrodes where it should, the gap is too wide. Where the tool cannot fit between the electrodes, the gap needs some widening. If the fit is close to the measurement, you can proceed to install the plug. Do gaps need Denso Iridium spark plugs? In most cases, you will find that you can use the plug without gapping it.
It owes to the specs manufactured at present. However, when dealing with a modified engine, you should adjust the NGK iridium spark plugs as needed. In this way, you can tell if the 49cc spark plug gap will work for the plug you have in mind.
You can now use your tool to adjust the bottom electrode. It should be such that you hold the spark plug with the electrodes facing the floor. From here, you can bend the bottom outward or inward, based on the gap needs. Ensure that you do not bend more than 0. If you damage the plug, misfires are likely to happen.
Where you cannot bend the plug using the tool, you can make the adjustment on a flat surface to add to the pressure.
You can now measure the gap again and make adjustments where you deem it necessary. When doing so, you should not touch the center electrode as you could damage the core. If this happens, you will need to get another plug. It also helps to be gentle during this exercise; else, you will snap off the electrode. Use as little pressure as you can when bending, and you should be fine. Note that some plugs come pre-gapped, and you can find this information on the inside flap of the box. In this case, you will not have much work to do.

Since all trucks are different, and all lifters are different, prices vary from truck to truck and between lifters. Add to this the variations in mechanic fees and labor costs, and you will find differences even when
