87 and up intake manifold
i have an 86 mustang, and i'v come to learn from some of u that the 87+ manifold makes more hp. is it the upper or lower intake that is different, or is it both?
i can get an 87+ UPPER INTAKE ONLY with throttle body for like 25$ from my friend, will it still make a difference being just the upper?
