:pHey everyone! I have a Cobra Hi-Rise intake manifold on my GT/CS. It is a four holer plenum type. My question is, drumroll please..............I have noticed the split plenum design on another Cobra Hi-Rise. I have been told that the four holer was designed for low to mid range rpm's and the split plenum Hi-Riser for mid to upper rpm's. Inquiring minds wanna know! Does anyone within SETI's earshot know anything about this? ET phone home, Captn Kirk out!
