Some modifications to your 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. 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. If purchasing this version online be sure to specify during checkout in the "Comments" section.
