CX-5 Turbo 87 vs 91 octane

It's all about carbon atoms and how they line up. They're reactive, and the high octane is more combustible, allowing it to withstand more detonation and knock. Top that off with better cooling capacity, and you have a recipe for more power and efficiency. Think E85, you can make a s*** ton more power on E85 because it is highly resistant to detonation.
 
The Mazda spark plugs are just NGK's with a markup. I regret buying the Mazda ones and not just grabbing the NGK's.

Glad they dont make Made in Japan, Thailand, and Mazda value line Made in Mexico, because theyd be charging $300 for the Made in Japan ones and suckers here would be eating them up!

Ill take the NGKs all day. Best spark plug maker out there anyways.
