Oil Pan Stud Kit Honda/Acura K-Series

The Oil Pan Stud Kit Honda/Acura K-Series (MOR38921) is an essential upgrade for K-series engine builders and tuners working on high-revving or turbocharged platforms. K-series engines—found in DC5 Integras, EP3 Civics, FN2 Civics, and Acura TSX models—generate significant crankcase pressure and vibration under aggressive operation, making factory oil pan fastening inadequate for sustained performance or nitrous/turbo applications. This MOROSO stud kit replaces vulnerable stock bolts with precision-engineered studs, eliminating oil pan leaks and catastrophic engine damage caused by fastener failure.

MOROSO studs deliver superior clamping force and vibration resistance compared to standard bolts through consistent thread engagement and reduced fastener stretch under thermal cycling. The stud design allows technicians to pre-torque studs to exact specifications without the rotational stress that compromises bolt preload, a critical detail when working with aluminum pan flanges prone to galling. Compact at 0.355 lbs and measuring 4 x 1 x 5 inches, this kit integrates seamlessly into engine bay configurations while providing the thread geometry needed for reliable, repeatable assembly across multiple rebuild cycles.

Professional engine builders, drift competitors, and track-focused enthusiasts rely on this kit for K-series platforms destined for sustained high-RPM or forced-induction duty. Installation is straightforward on a bare block or existing engine, requiring only removal of the factory oil pan and fasteners followed by stud installation with appropriate washers and locking nuts. This upgrade is non-negotiable for any K-series build exceeding 8,000 RPM or producing boost, ensuring oil delivery consistency and eliminating leaks that plague stock fastening systems under stress.
