240zV8 Posted September 5, 2006 Share Posted September 5, 2006 I'm gonna make my own cold air intake and just wanted to see if you guys knew of a stock hat (filterless) that would fit a 91 chevy 5.7l truck tbi unit so i can run 3" pipe off it and put a k&N filter on. Simple install, just wondering what i can pickup at the junkyard that will screw on for a quick cold air intake to the tbi without air leaks. And another question...is a 1" tbi spacer worth the money for gains in power or mpg? Quote Link to comment Share on other sites More sharing options...
spotfitz Posted September 5, 2006 Share Posted September 5, 2006 TBI as in carb looking, with injectors? I'm not sure what the '91 came with. If so, PM me. Quote Link to comment Share on other sites More sharing options...
