Though older than many cars on the road, your C4 is still capable of the kind of mind-blowing power that makes any Corvette a formidable sportscar. The C4 engines, in fact, have a great deal of latent power that can be tapped with relatively small modifications. These BBK throttle bodies bolt on quickly and easily and can net a gain from 7 to 12 HP.
These BBK Throttle Bodies for your C4 are engineered to increase airflow to your tuned port injected L98. Since they are CNC machined from 356-T6 aluminum alloy castings, you are guaranteed a fit that is superior to OEM. Combined with OEM die stamped throttle linkages, double sealed bearings, and o-ringed throttle shafts these are the only throttle bodies that will last as long as your C4.
