colder heat range spark plugs to use with nitrous??
Hoping someone can give me a product number for a spark plug that is one heat range colder than the OE plug in a 2017 SXT Plus 3.6L....I've been going back and forth with NGK they tell me I need #SILKR8E8D. Apparently that is a special plug for a very unique application that is not for sale in Canada. I am having NO luck finding these plugs anywhere. Hopefully someone here can point me in the right direction...
