If you're buying spark plugs online, you should probably be told about what we came to learn though testing over $500 worth of NGK Laser Iridium Champion Iridium and Denso spark plugs - and that's around 1/3 of them out there seems to be just fake. We go through how to spot that and what you might be able to test to determine if what you receive is legit.
