Does anyone know if there are any companies that manufacture intake systems (tube form) for '94 S-10 4.3L TBI engines? I checked many places...K&N has an intake kit for the CPI engine. I believe APC makes intakes for 94 V6's but they don't specify whether they are for CPI's or TBI's; all they say is that they work with for my truck w/ or w/o air conditioning. Any info. would help.
