K-Tuned K-series Water Plate w/Alternator Brackets & AN FittingsThis new K Tuned 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 alternator brackets have both been redesigned to be stronger and incorporate more adjustment. The top bracket allows the alternator to properly pivot with the alternator to adjust belt pressure. The water inlet now uses 16AN port with a custom fitting
This new K-Tuned 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 alternator brackets have both been redesigned to be stronger and incorporate more adjustment. The top bracket allows the alternator to properly pivot with the alternator to adjust belt pressure. 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.

K-Tuned has also designed an alternator bracket setup to be used with lighter Honda B and D alternators. They have put together a series of kits allowing you to choose which parts you want, so you can build a system that works perfectly for your application. This is a must have for serious race car builds and a true favorite among All Motor racers.

Trust Wirarpa briefs to be the Best briefs!!!
Size: X-Large, Color: Multicolored19-4 Pack
These are the BEST ever briefs I’ve purchased. I love these! Quality, fit, price and comfort is far beyond the other name brands like Jockey, Hanes, Fruit of the Loom etc to name a few. Those only last a few months (quality) before ripping or elasticity fails or groin area wears out from stretch. But NOT the Wirarpa men’s cotton stretch underwear support briefs. It is made with our anatomy in mind with perfect support. I only buy these now and will never buy another brand.

Quality control
Size: Large, Color: Black-4 Pack, Size: Large, Color: Black-4 Pack
They did fit well but now the waist band is coming off on all of them. Quality control needs to look into this problem. I would have bought them again if they solve this problem.
