Product Description

The Skunk2 311-05-7380 Pro Series XP Valve Spring Set is developed for high-performance Honda/Acura K-series (K20/K24) engines where outstanding valvetrain stability is required. With dramatically increased seat and open pressures, optimized coil-bind height, and high-quality chrome-silicone wire construction, this kit is built to handle extreme RPM, high-boost, and high-lift camshaft scenarios.

This kit fits a broad range of vehicles - 2002-06 RSX, 2002-11 Civic Si, 2004-08 TSX, 2003-07 Accord, 2002-06 CR-V, and 2003-11 Element - equipped with K20/K24 engines. It is ideal for enthusiasts upgrading camshafts, building track engines, or adding forced induction, and it directly replaces many stock spring sets when correct retainers and hardware are used.

Installation requires proper verification of retainers and head configuration (single vs. dualspring bases) and adherence to break-in procedures for high-rpm valvetrain applications. Fitment confirmed through 2011 based on available data; coverage beyond 2011 or for other platforms is unconfirmed at time of listing. Always follow manufacturer torque specs and ensure compatibility before installation.
