This kit includes everything needed to switch out and upgrade the oil pump system on your K24.  The factory oil pump on the K24 tends to cavitate at 7500 RPM and many have seen catastrophic failures when repetitively approaching the lower 8,000 RPM range.  The K20 Oil pump kit we have for you is tested and proven to work at 9,000 RPM's without failure or cavitation.  This swap is a given to anyone who is building a engine or performing the swap who plans on taking it to the track.  All parts are new and OEM.
