Throttle body spacers fact or fiction

Considering the throttle body on the N62 doesn't really do anything...go for it. TB Spacer is meant to speed up air flow. Your infinitely variable length intake manifold already does that.

You could combine the intake, a larger bore throttle body, and software reprogramming to gain 8HP according Dinan. Maybe you'll feel the 2% increase in power, but you'll definitely hear a difference.

variable intake doesnt speed up air. it increases or decreases the intake runner length, it makes the air path longer or shorter to the cylinders. longer for low end torque and shorter for high end power

900$ for 8 hp is waste of money, ur looking at 2000$ for a sad increase in power, might aswell save up 10,000$ and get a supercharger kit

Spacer is for air turbulence i just wanna know if its worth it because it advertises 10hp, and for 150$ if it gives 5hp it is more cost effective than a 900$ TB for 8hp
