Just wondering does anyone run a airbox with throttle bodies. Hearing my car on track (someone else driving) I think it's pretty clear I'm going to struggle anywhere with a drive by limit - the noise of it on full chat from the front is ridiculous. As much as I love it I just know if I go anywhere with a reasonably tight limit I'll have no chance,   So looking into options and the obvious choice is a airbox.   Question is do they make a huge difference?   Do they have a negative/positive effect on power?   Also I see some can encorporate a sausage filter in the box and some will run to a cone filter on the end of the intake tubing? Again which is the way to go?
