PRODUCT DETAILS
KPower RWD K Swap Cast Intake Manifold
The KPower RWD K Swap Manifold is built specifically for rear-wheel-drive K24A2 (RBB) setups that need OEM manners but don’t want to leave power on the table. This RWD K24A2 intake manifold works with K-swapped Miatas, Honda S2000 K swap builds, BMW K swap cars, and Nissan RWD K swap projects, with a focus on clean fitment, repeatable performance, and durability you can actually trust. Dyno and track testing back it up as one of the most sorted KPower K Series Manifold RWD options out there. We run this same hardware on our own cars.
The KPower Cast Aluminum Manifold uses a forward-facing RWD K Series throttle body layout, which makes charge piping and intake routing in tight engine bays a lot less annoying. You’ll get extra clearance around belt tensioners, idlers, wiring, and common service points, so you’re not fighting the car every time you wrench on it. It’s cast from A356-T6 heat-treated aluminum, so it holds its shape and sealing surface under real heat and real abuse. The 3-liter plenum volume works well on stock K24A2s and built motors, giving you strong mid-range while still carrying power up top—KPower has repeatedly seen better mid-range than a Skunk2 Ultra Street in RWD layouts.
This KPower Miata K-Swap Manifold uses a 74mm inlet that fits B-series throttle bodies or a drive-by-wire unit with an adapter, making it a solid base for a full RWD K swap manifold kit. You also get an integrated K-series MAP sensor port, IACV port, throttle cable bracket mount, and the option for a K swap RBB water passage / RBB-style water port. That makes it easier to bolt this RBB engine cast manifold onto different K-series head variants without a bunch of weird custom plumbing. Matching gaskets, hardware, and fittings are available so you can put together a true bolt-on KPower Intake Manifold K24A2 setup.
Key Features
- OEM-style cast aluminum RBB engine cast manifold construction
- Forward-facing RWD throttle layout for clean routing in RWD bays
- Stronger mid-range torque vs. common aftermarket manifolds like the Skunk2 Ultra Street
- Improved engine bay fitment for K Swap RWD Miata manifold, S2000, BMW, and Nissan applications
If you’re wrapping up a fresh RWD K swap or stepping up from a hacked-together intake, this forward facing RWD manifold hits a nice middle ground: OEM-style reliability with real, tested performance. Pair the KPower RWD K Swap Cast Intake Manifold with KPower’s 74mm B-series throttle body, a drive-by-wire setup with adapter, their fuel rail, and ID1050XDS injectors, and you’ve got a straightforward high-flow intake package that actually improves power and drivability instead of just adding under-hood jewelry.
