Stock St205 raising boost to 14psi Options

[cax_11]

If I raise boost to 14psi,do you recommend i get colder plugs??

"Copper spark plugs are generally considered to have the best performance of any spark plug type"-- this is due to it being a better conductor speaking purely from an electrical standpoint----"This is potentially different from what advertising companies suggest, but the other metals are, unfortunately, not as conductive in general as copper is"

"Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat"


this is also a problem with running these types of plugs. with increased boost pressures it becomes harder for the ignition system to push the spark across that gap.
Should I gap my Iridium Plugs?
The manufacturers say NO.
This is because most people do not know how to properly gap a spark plug, and the center electrodes on the ultra-fine iridium can easily snap if mishandled. There is no warranty for snapped center electrodes. The manufacturers say an iridium spark plug will run so much better than a traditional plug, even if it is not gapped for that motor, that they would prefer you just leave it rather than risk snapping the center electrode.
Personally, we at ChampionSparkPlugs.com, gap our iridium plugs for our own vehicles (we’re rebels). If you insist on gapping your iridium plug, please refer to Proper Gapping for instruction. ---source

this is why platinum and iridium plugs last longer. they resist this erosion due to being a stronger metal.
The central electrode is usually the one designed to eject the electrons (the cathode) because it is the hottest (normally) part of the plug; it is easier to emit electrons from a hot surface, because of the same physical laws that increase emissions of vapor from hot surfaces (see thermionic emission). In addition, electrons are emitted where the electrical field strength is greatest; this is from wherever the radius of curvature of the surface is smallest, i.e. from a sharp point or edge rather than a flat surface (see corona discharge). It would be easiest to pull electrons from a pointed electrode but a pointed electrode would erode after only a few seconds. Instead, the electrons emit from the sharp edges of the end of the electrode; as these edges erode, the spark becomes weaker and less reliable. --- and yes i know its wiki source

i cant find anything right now that talks about the heat dissipation characteristics of each, but copper is a cooler plug compared to the others of the same heat range. ill keep searching for something on this. honestly in the end run whatever makes oyu happy and what you want to pay for.
