SparkPlugs.com is holding a spark plug contest! You will find a spark plug quiz below, all of the answers can be found on our website. Please e-mail your answers to Natasha@SparkPlugs.com. The contest is open until December 22nd. Any member with 25 posts or more can participate. Whoever gives the most accurate answers, or gets the most correct, will receive one set of NGK iridium spark plugs on the house. The winner will then need to do an installation and product performance review within 2 weeks after they receive the plugs. The review should show their installation process and a review of their impression of the product and its performance. Let me know if you have any questions!

I thought i'd post the answers to the quiz for any who are interested. The short, simple answer is first, with a more detailed explanation below it. You guys found some loop-holes and trick questions that i didn't even know i created, so i hope this answers any questions! 
Spark Plug Quiz:
1. What are the 9 product brands carried by SparkPlugs.com?
K&N, Autolite, Denso, KYB, NGK, Champion, Splitfire, AFE, and Michell1 Manuals
AFX Air/Fuel Ratio Monitors are a product made by NGK
2. How many of those are spark plug manufacturers?
5
Autolite, Denso, NGK, Champion, Splitfire
3. What are the three precious metals premium spark plugs are made out of?
Gold Palladium, Platinum, Iridium
4. Are standard spark plugs made with copper or nickel?
Nickel
All spark plugs (iridium, platinum, standard, etc.) have a copper core running through the center. When we're talking about plug types or metal types (platinum, iridium, nickel) we're referring to the material the electrodes are made of. Copper is too soft to use on any exposed part of the plug,
so the electrodes on standard spark plugs are made with nickel. No one understands why standard plugs are referred to as "copper plugs" - this designation is inaccurate.
5. What does RFI stand for, and how do you prevent it?
radio frequency interference - and you can prevent it by placing a resistor within the spark plug.
6. Can Platinum plugs be used with nitrous?
No. There have been instances where the platinum tip has lost its bond to either the center or the ground electrode when used with nitrous.
7. Can Iridium plugs be used with nitrous?
Yes, according to the techs, there have been no reported problems with using iridium plugs with nitrous (or a blown alcohol motor.)
8. What are 5 types of modifications that may make it necessary to change your spark plug heat range?
If you make modifications such as a turbo, supercharger, increase compression, timing changes, use of alternate racing fuels, or sustained use of nitrous oxide, these can alter the plug tip temperature and may necessitate a colder plug.
9. What is the heat range vs. hp increase rule of thumb?
A rule of thumb is, one heat range colder per modification or one heat range colder for every 75–100hp you increase.
The most accurate rule to go by would be one heat range colder for every 75-100hp you increase, as some mods do not increase horsepower, and therefore do not neccesitate a change in heat range.
10. Is it better to have too hot or too cold a plug? Why?
When making spark plug heat range changes, it is better to err on the side of too cold a plug. The worst thing that can happen from too cold a plug is a fouled spark plug, too hot a spark plug can cause severe engine damage
11. Do “fine wire plugs” refer to the ground electrode or center electrode?
Center Electrode
There are many variations to the center electrodes and ground electrodes that come under a variety of names. Specialized center electrodes may be called Fine wire, tapered point, ultra-fine electrode, taper cut electrode, necked down electrode, v-power electrode. Specialized ground electrodes may be called V-trimmed, trapezoid cut, cut back ground, fine wire ground, wedge shaped ground, inverted v-tip, tapered cut, trimmed side electrode, angled ground strap, u-groove. The ground electrode features add slight benefits to the plug, however, the family of fine wire center electrodes bring great improvements and the term "fine wire plugs" refers to plugs with a fine wire center elec
