...if you cut a notch in the radiator fan housing. The clearance is probably less than an inch between the fan and the rubber elbow of the air intake...but the whole thing seems very secure. Have had it running for a week with no problems. Because I installed the air intake at the same time as the throttle spacer...I don't know which unit to give credit to the little extra 'kick' in performance I have. My check engine light came on after 2 days....don't know if that's related.....
