    Amazing
    I honestly dunno how else to rave about this product other then amazing. You can feel the difference in the throttle response almost immediately as you accelerate. The difference is night and day not to mention the increase in horsepower this baby added 12 hp to my 350z dyno tested yesterday and you can definitely feel the difference. Couldn't be happier the only downside is that you have to purchase the gasket separately which is kinda silly i would highly suggest Hitachi include it with the throttle body as it should come inclusive. Other then that definitely worth the money you pay for this and i highly recommend other Z owners to change their throttle body to the manufactured version you definitely wont regret it!
