CNC Port Matched 70mm Jeep 4.0 Intake Manifolds(Stock Castings)
We brought them back, that's right we now carry "CNC" Port matched Jeep 4.0 Stock Casting Intake Manifolds in all styles. If you are looking for that added kick in the seat of the pants this is an easy upgrade. Whether it's a stock 4.0 or a big stroker these manifolds will add hp and tq across the board with killer throttle response.
All manifolds are cleaned, blasted, resurfaced, bored and CNC machine gasket matched to our Copper intake/exhaust manifold gasket. The runners have been greatly opened up from the very restrictive factory injector bung area and the throttle body opening has been machined to 70mm if you decide to upgrade to an oversize throttle body. We now carry custom 70mm throttle bodies in Silver and Black.
You can simply choose your current year intake manifold or mix it up depending on where you want your power delivered. Make sure when choosing a manifold to select either your current year or the matching power steering mount pattern/style.
How to choose your manifold: The early Straight Runner Manifolds make great mid-range and top end power (Stockers or Strokers with a slightly aggressive cam will benefit in the upper power band). The later Curved Intake Manifolds absolutely make more power off idle for you low end to mid-range power lovers with those long runners and big plenum (Small cu in or small cam lower rpm seekers this is your intake).
If you are retrofitting an older straight runner to a newer curved style you will need to choose the "99-04 Curved w/o harness bosses.
**While supplies last we are offering our in house 60mm Taper Bore Throttle Bodies as an option, these work great on stock motor upgrades or low to mid rpm response.
***CORE REQUIRED, if you do not have a usable core of the same intake manifold as you purchased then you will have to choose and pay the associated core charge at checkout. If you do have a usable core then simply ship it back in the same box as delivered. You will be responsible for shipping charges.
****As of 01/09/24 we have added High Temp Cerakote coated intake manifolds to the options list. We have used this coating now for a few years on intakes, headers, etc with great success. This coating is good to 1,800 degrees and is currently available in Black or Silver to match our 70mm throttle bodies.
