Guys I need to know what the width of the upper intake manifold is. By width I mean that if you look from the front of the car, from where the manifold is closest to you, to where it almost touches the firewall, what's the measurement on that? If someone with a 20b can measure that real quick and let me know, that'd be great. Thanks beforehand guys....
