The spark plug are many points, in terms of materials are: nickel alloys, platinum and the like, these materials themselves have good electrical conductivity. A cold heat sink in the form of spark plug-type ignition plug and hot spark plug, the spark plug electrode structure mainly monopole, dipole, quadrupole and the like. For which want to improve vehicle ignition performance reasons, many people will think of his own unipolar spark plugs changed multipolar, or will own nickel alloy platinum spark plugs changed.
for unipolar and multi-level, not discussed in this article, but said spark plug of different materials, is it worth to replace it? From the price point of view, although the precious metal spark plugs, but can offer with respect to the hundreds of million of the purchase price is concerned, it is not the absolute value of tens of dollars more expensive than nickel alloy, why does not the original adoption of these precious metal spark plug it ? It is entirely because of cost? Or something else? Clarify this issue, we can figure out our own car is not worth the replacement of platinum spark plugs.
The spark plug is composed of two parts consisting of an insulator and a metal shell, the metal shell threaded, is screwed on the engine block, a center electrode a metal housing, it is insulated by an insulating material and the metal housing with wire nuts at the upper end of the center electrode, the connection from the distributor over the power lines, but also in a metal case is welded below the ground electrode between the center electrode and the ground electrode has little gap, pulse high-voltage breakdown of air between the two electrodes, a spark ignited gas mixture can then work, work due to the high temperature and pressure of the spark plug harsh environment, its materials and manufacturing processes require very high, but in most often used economy cars spark plug nickel alloys, high-end cars will only use platinum spark plugs or platinum spark plugs.

Many riders believe that the manufacturers do not give their own cars with platinum spark plugs, entirely because of cost considerations, are cutting corners performance, and therefore very angrily to pay their car far from the spark plug replacement spark plug replacement cycle of nickel alloy is platinum. Such a replacement is clearly out of consideration for performance rather than durability. It is estimated that nine out ten car lovers feel disappointed, because this performance upgrade is really limited, even did not feel it. In fact, this is the main reason for the original precious metal spark plug is not used.

to improve the ignition performance of the engine is a systematic project, change the spark plugs on engine performance alone will not be much difference. Since the ignition system of the engine mainly by the high voltage, ignition coil, distributor, spark plug and other components. We want to improve engine performance fundamentally, we first need to consider upgrading the ignition voltage, higher voltage in order to provide greater ignition energy. After the boosted voltage on the replacement of good conductivity and diameter of the coarse high voltage, a high voltage since the conductive cross-sectional area and its length with materials, if the diameter too small, and a long lead wire containing more impurities will affect the ignition performance. Only after these replacement only necessary to consider replacing the platinum spark plugs. Note here that it is only to consider, but not necessarily, because at this time, if not replace platinum spark plugs, ignition performance can also be promoted.

and single pole and multi-level difference between different platinum spark plugs major advantage of not increase the ignition energy, but to improve durability. It’s much longer than the life of a nickel alloy, more suitable for poor working conditions, for high-performance engine, it is more durable and stable work. As for performance, its ignition energy of ordinary nickel alloys are similar, of course, be some advantage in terms of rate of fire, but more out of its high-revving engine to meet the design requirements, and this advantage is not obvious. So when we modify the entire ignition system after the engine operating conditions become more strengthened, the combustion chamber of the work environment has become more severe, so the use of platinum spark plugs advantage is manifested.
As for the lower-priced economy car, the more it is a design-oriented economy, in the case to meet the daily means of transport, excluding more does not make sense to strengthen. As spark plug nickel alloy, fully meet the demand for such models work, although about 30,000 km need to be replaced every time, but much lower than the cost of platinum, the whole cost difference is not significant. Of course, the replacement of the latter will bring some after-sale profits to the manufacturers, the manufacturers and this is one of the factors taken into account, but not the main.

platinum spark plugs biggest feature is the long life, good durability, more suitable for harsh working conditions. Therefore, when the member does not make any other changes, spark plug replacement of platinum, generally only play the role of a delay period, plug change, and for the improved performance is very limited. For those owners do not want to completely modify the ignition system, if not yet the time to replace the replacement cycle of platinum spark plugs in the original spark plug, it is worth the candle.
And if simply to expect from the performance point of view to replace the platinum spark plugs, or give up the best, because the replacement effect is difficult to produce in the future so you have no surprises. If life is out of consideration, their vehicles is relatively poor, more short-term driving range, do not want to go to the pits to replace the spark plugs frequent riders, using platinum spark plugs it is possible, which can reduce the number of replacement, and improve work effectiveness.
