Moroso Notched Steel K Series Baffled Oil Pan for RSX/EP3/TSX

Moroso Notched K-Series Baffled Steel Oil Pan - RSX / EP3 Civic Si / TSX & K-Swap (20919)

The Moroso notched K-series baffled oil pan is built for road and drag racers who need their oil supply to survive hard driving. What sets this version apart is the notch: it's cut for extra chassis and subframe clearance, which lets it bolt directly onto the factory K-series cars, the RSX, EP3 Civic Si, and TSX, not just older K-swaps. It's a steel, wet-sump pan with race-proven baffling that keeps oil over the pickup under the braking, cornering, and launch loads that starve a stock pan.

Why The Notch Matters

Most K-series race pans are built for swaps into older chassis and won't clear the subframe on the factory RSX, EP3, or TSX. This one is notched specifically for that chassis fit, so it drops in on the cars that came with the K-series from the factory and still works for swaps into the older platforms. If you've got an RSX Type S, an EP3 Civic Si, or a TSX and wanted a baffled pan that actually fits, this is the one.

Race-Proven Oil Control

The pan uses a trap-door assembly and anti-slosh baffle to keep oil stable and available to the pump during hard driving, which is the whole point, oil starvation under sustained cornering or launches is what spins bearings. It also adds capacity, holding up to two quarts more than stock, so there's more oil in reserve and more thermal headroom during intense sessions. For road or drag use, that combination of baffling plus extra volume is real engine protection.

Built For Performance Setups

The pan includes 1/2" NPT fittings for a supercharger or turbo oil drain-back and for an oil temperature sender, so it's ready for boosted and instrumented builds. It's designed to be used with the Acura RSX oil pump assembly and windage tray for the best results, and it includes a magnetic drain plug to trap metallic particles between changes. Construction is durable steel with a black powder-coat finish.
