大部分的人，大概都是買了火星塞就直接用.....
很久以前看過ngk的網頁，裡面提到一些地方給各位看一看.....
火星塞也是要做設定的......

3. Gapping
Since the gap size has a direct affect on the spark plug's tip temperature
and on the voltage necessary to ionize (light) the air/fuel mixture, careful att
ention is required. While it is a popular misconception that plugs are pre-gappe
d from the factory, the fact remains that the gap must be adjusted for the vehic
le that the spark plug is intended for. Those with modified engines must remembe
r that a modified engine with higher compression or forced induction will typica
lly require a smaller gap settings (to ensure ignitability
in these denser air/fuel mixtures). As a rule, the more power you are making, th
e smaller the gap you will need.
A spark plug's voltage requirement is directly proportionate to the gap size. Th
e larger the gap, the more voltage is needed to bridge the gap. Most experienced
tuners know that opening gaps up to present a larger spark to the air/fuel mixt
ure maximizes burn efficiency. It is for this reason that most racers add high p
ower ignition systems. The added power allows them to open the gap yet still pro
vide a strong spark.
With this mind, many think the larger the gap the better. In fact, some aftermar
ket ignition systems boast that their systems can tolerate gaps that are extreme
. Be wary of such claims. In most cases, the largest gap you can run may still b
e smaller than you think.
