Port Matched 70mm Jeep 4.0 Intake Manifolds(Stock Castings)
We brought them back, that's right we now carry Port matched Jeep 4.0 stock casting intake manifolds in all styles. If you 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, 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 openings have machined to 70mm if you decide to upgrade to an oversize throttle body.
You can simply choose your current year intake manifold or mix it up depending 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 retro-fitting an older straight runner to a newer curved style you will need to choose the "99-04 Curved w/o harness bosses.
