Some modifications to your coil pack mounts and upper intercooler pipes may be needed as this manifold sits down a lot lower than stock. If using the Accufab and other aftermarket throttle bodies please note that the throttle cable and TPS sensors may need modifying.  We recommend running at minimum a 70mm TB with this manifold.  If you need additional vacuum ports our Vacuum Distribution Block is a great option for up to 6 more ports.

Also available is a RWD version of this manifold for no extra cost, perfect for the custom 4G63 swap into a rear wheel drive vehicle.
