Great For Use On Street Rods!
Clamps directly onto GM TPI throttle bodies using 1990-92 stock or 1985-89 TPI that has been converted to speed density. 599-RC5000 will flow approximately 600 CFM and is intended for stock throttle bodies. 599-RC5050 is capable of flowing about 1000 CFM and is the perfect choice for aftermarket systems that need more air. Great for use on street rods where space is a problem or just to get rid of some weight by removing a bulky stock air box. Requires no modification to throttle body. Will not work with mass-air system. Will not fit LT1.
