While alot of today's cars are pretty much fuel efficient with stock setups, I figured trying out some different spark plugs wouldnt hurt. I swapped out the CYFS12Y2 spark plugs with these NGK 96588 on my 2018 EcoBoost Mustang...I honestly dont recognized my car's engine anymore. The MPG went from 26 to 35, the acceleration was alot faster, BUT these plugs do generate a lot more heat in the engine bay. Surprisingly, the engine itself got alot more quieter than before! So if you're up for some more fuel savings and better acceleration, pick up a set of these plugs. You wont be dissatisfied!
