Description

Each intake runner is equipped with velocity stacks to ensure optimal airflow. This comprehensive kit includes a billet intake manifold, a 14mm top feed fuel rail compatible with 48mm and 60mm injectors, and a 90mm billet throttle body. It also comes with an IACV delete plate and necessary hardware for installation. The manifold boasts a fully TIG-welded construction and a high-polished finish, adding a visual complement to any engine bay. When installing this manifold on a Right-Hand Drive (RHD) chassis, depending on the specific chassis, sub-model, and clutch master cylinder, a swap to a different OEM clutch master cylinder may be required to ensure adequate clearance for the plenum. Additionally, the intake has provisions for an OEM IAC, but please note that the NEO IAC will not bolt on; this kit will work on a NEO Head, but a non-NEO IAC will be needed.
