As posted above, that's an Edelbock CH4B that someone has ground all aftermarket ID markings off it, only leaving the Hustle Stuff part #. It flows more and the ports are larger than stock. The goal is for 'Stealth', make it to appear and pass for a stock intake. The most tell tale sign that gives it away is the coil is not in the OEM location. The CH4B is the perfect intake for a day two resto.
