Turblown 20B 3 rotor intake manifold

We are currently in dyno testing phase with our sample sideport units. Full production will start on 100 sideport models the middle of July, and take an estimated 60 days. Semi pport samples are still underway, and will trail behind by 30 days estaimted. 

This lower intake manifold comes with its own 8AN ORB fuel rail designed for 48mm grey top ID injectors( 14mm upper and lower o rings). 

Lower intake manifold is O-ringed at UIM flange,  no emissions ports(off road/compeition use only)

Equal length runners compared to the OEM, this greatly improves engine reliability and throttle response. Tapered runner design, with less internal restrictions, and gentler bends will also increase power. 

This unit is 40mm lower than the OEM LIM, to accomdate more hood clearance for engine swaps. This also shifts the powerband up slightly. Additionally secondary port runners are 8% larger for increase airflow. These will bolt to the OEM upper intake manifold( we do advise port matching the secondary runners if using the OEM UIM). Mounting hardware/o-rings are included.
