I have to put in my opinion.
First things first, the mazda speed emblem is really lame because you dont have anything to back it up and people are just going to laugh at you. Second its going to make us all look bad. I would be emberassed to put that on my car. Next the plastic intake manifold is actually the newest thing out. Its a variable intake manifold. All the new cars have it. It actually helps the car run more efficiently than fixed intakes. Those plastic tubes that look kind of like headers in the front of the engine are part of the intake system. It helps vary the amount of air going into the engine. Do some research before you go dissing what we have that your car doesnt.
