Recently K-Tuned released a K-series Water Plate Kit which utilizes the K-Series Alternator. Now, they are excited to provide a redesigned Water Plate Kit for B-series alternator use.

The new water plate kit now incorporates two o-rings seals. You no longer need to seal the water plate with Honda Bond. This will make it easier switching the water plate between blocks. The water inlet now uses -16AN port with a custom fitting which allows eight different positions.

For several years now racers have used electric water pumps to reduce the power robbing effects of parasitic drag from their engines. By reducing the number of accessories the crank needs to turn there can be some impressive gains. The K-Tuned Water Pump Block Off Plate system was designed to setup a K-series engine to run an electric water pump cooling system. It replaces all the bulky and heavy OEM accessories with a simple lightweight aluminum plate. The kit is designed to allow the perfect flow of coolant and also effectively release unwanted crankcase pressure. The water port is sealed just like it was from the factory using an o-ring seal. The breather port is threaded for an 8AN fitting and can easily be routed to any catch can set-up.

Works perfect for BMW S63 engine.
I used this to change the oil on my BMW M8 with the S63 engine. It was a perfect fit. It extended far enough onto the filter housing to be quite secure with no risk of slipping off and stripping the housing. It was snug on the housing and did not bind up due to having a loose fit. The tool feels well-built and I suspect it will outlive me given my occasional personal use. It would still probably hold up well even for daily shop use as long as it was not abused (repeatedly dropped, slammed around, etc).
