Message Hi Ash,

How are things going? Sorry my last email was so harsh, but you need to make this right and stop blowing me off and talking in circles. I think we both know what really happened. I'm giving you one last chance to negotiate compensation with me, before I blast you on every known Z related forum on the web. I'm very well known in the Z community and have a very solid reputation. I'm giving you till Tuesday 8/19/08 to contact me and work this out. I've decided that I'm going to need at least $2000 from you for the damage incurred. I can provide receipts for everything, but I'm not charging you for overnight shipping to and from Kyle, which was $300 each way. Check out the info below and I hope to talk to you soon.

Please check out this link to a recent TT.NET post. I believe the gentleman responding to me is fairly knowledgeable.

Also, please view the info below which I cut and pasted from NGK's website:



Tech Info - Spark Plugs Overview

A spark plug's heat range has no relationship to the actual voltage transferred through the spark plug. Rather, the heat range is a measure of the spark plug's ability to remove heat from the combustion chamber. The heat range measurement is determined by several factors; the length of the ceramic center insulator nose and its' ability to absorb and transfer combustion heat, the material composition of the insulator and center electrode material.

Heat rating and heat flow path of NGK Spark Plugs


The insulator nose length is the distance from the firing tip of the insulator to the point where insulator meets the metal shell. Since the insulator tip is the hottest part of the spark plug, the tip temperature is a primary factor in pre-ignition and fouling. Whether the spark plugs are fitted in a lawnmower, boat, or a race car, the spark plug tip temperature must remain between 500C-850°C. If the tip temperature is lower than 500°C, the insulator area surrounding the center electrode will not be hot enough to burn off carbon and combustion chamber deposits. These accumulated deposits can result in spark plug fouling leading to misfire. If the tip temperature is higher than 850°C the spark plug will overheat which may cause the ceramic around the center electrode to blister and the electrodes to melt. This may lead to pre-ignition/detonation and expensive engine damage. In identical spark plug types, the difference from one heat range to the next is the abil ity to remove approximately 70°C to 100°C from the combustion chamber. A projected style spark plug firing tip temperature is increased by 10°C to 20°C.
