Mike: The heat range of a sparkplug is indeed important. You generally want to run as cold a plug as you can until the plugs start fouling. An example would be NGK rates their plugs on a numerial scale 1 through xxx. If the number 10 worked, but the number 11 fouled, you would want to use the 10, rather than the 11. It all depends upon the type of driving you do, and the power of your ignition. Art | ||

mike -- Try the NGK website for the resistor vs non-resistor description: http://www.ngksparkplugs.com/techinfo/spark_plugs/faq/faqresistor.asp There is no "better" for heat range -- you want to select a heat range that puts/keeps the spark plug tip in the self-cleaning temperature range for your particular driving situation: http://www.ngksparkplugs.com/techinfo/spark_plugs/faq/faqheatrange.asp For NGKs, the lower number is the hotter plug (but this varies manufacturer to manufacturer) | ||

What's that really mean, "resistor" versus "non-resistor" type sparkplugs? I read that Daytona thread about sparkplugs and heat ranges, but it doesn't really tell me if hotter or cooler is better. From what I can tell, the "6" series is hotter than a 7 or 8 series? | ||

The Champion N6GY cross-references to NGK BP8EV (which is a rather cold non-resistor plug so it's not unreasonable at all IMO that NGK BP6EV was used). This link shows my take on heat range choices for US driving: http://www.ferrarichat.com/discus/messages/112/178416.html Unfortunately, NGK stopped making the less-expensive "V" (Palladium) series a few years ago so you'll need to go with either the "VX" (Platinum) or "IX" (Iridium) series � and they are not always available in both non-resistor and resistor types so you might have to go with a resistor type, but any of the following NGK should be OKish: BP6EVX BP6EIX BPR6EVX BPR6EIX PS � do a search here on �NGK� and you should get a lot of reading. | ||

The 1984 manual suggests Champion N6GY or RN6GY or N6YC or Bosch W6DS I figure there are better options now that it's 18 years later! But I don't know anything about heat ranges, etc... The last time plugs were changed, NGK Gold Paladium BP6EV were put in. | ||

mike 308 -- What is the "stock" spark plug (brand/PN) listed in the OM for your 308QV? Is it Champion N6GY? | ||

Ric (and others): What would you suggest as the best modern sparkplugs for a "stock" 308/QV? | ||

I get my NGK plugs at local shop, but bro-in-law got a set of NGK wires for his Miata (not bad cars by the way...) from Clubplug - seemed to be good service and prices. | ||

I agree as well. Clubplug.net is an excellent source for spark plugs - have ordered from them multiple times. I too learned of their site from FerrariChat.... | ||

just got my new platinum plugs for my daytona. It took a little longer than expected, but they were always prompt to respond to my emails. They did not have them in stock, they got them in and informed me when they shipped them. Coming from Canada, it took some 7 days to get here, but well worth the wait. I strongly recommend them. | ||

I just want to report that my NGK plugs showed up on time and as promised for less than half of what I expected to pay locally... ~$45, delivered 6 days, for 8 NGK plats for my 348. Thanks to the group for the recommendation.  |
