Hey guys new to the site so hope I'm doing this right but have some questions recently installed a k&n cold air intake works great and now woundering if new plugs and wires would make a difference if so what is recamended

 

Works great? You mean you didn't lose any power?

As for plugs and wires, don't waste your time and money, Mazda knew what they were doing when they built the car and the've specified plugs and wires which are optimal for the application.
