XV Motorsports has developed single plane intake manifolds to create serious horsepower with the 5.7 and 6.1 HEMI. Our manifolds were CAD designed, rapid proto-type tested and built to deliver maximum performance.
The manifolds feature a Holley 4150 mounting pattern, which will allow you to run a 4-BBL throttle body or carburetor with this manifold. The manifolds are being offered in either a carbureted or EFI version, with the EFI version machined to accept fuel injectors.
Factory manifolds were optimized to make power at factory levels. If you’re running a bigger cam, worked heads or have a stroker, you’ve only been seeing part of the power you could be making. Our manifolds are designed to flow much more airflow – the missing link to making big HP with the new HEMI engines!
Don’t want a cone filter under the hood? If you’re putting a new HEMI into an older vehicle or hot rod, this manifold will allow you to run carb style air cleaners, factory air cleaners, functional shaker hoods, etc.
We are also offering fuel rails to work with this manifold and 4-BBL EFI throttle bodies, as well as complete engine management systems.
This manifold is not suitable for use on pollution controlled motor vehicles and is intended only for racing and off-road applications.
