Here is another innovative part from K-Tuned.  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 the oem o-ring seal.  The breather port is threaded for an 8AN fitting and can easily be routed to any catch can set-up.


We have also designed an alternator bracket setup to be used with lighter Honda B and D alternators.  The 01-05 EM2 alternator is perfect to use with this kit because it will plug in directly to the K-series engine harness.  The EM2 alternators are also pretty easy to get and generally they aren’t too expensive either.  We 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.

Cute but run big
Special Size: 7" Inseam with Pockets, Size: X-Large, Color: Flamingo Pink
Color is fantastic. Very naked feeling. Runs big. I’m a size 12/14 and usually wear XL with them sometimes feeling tight. I am pear shaped - 35” waist, 47” hip and these fit but were quite loose in the waist. I might consider sizing down if I wanted to tighter. They would be very a bump-friendly non-maternity option

Love these!!!
Special Size: 7" Inseam without Pockets, Size: Large, Color: Ocean Blue
Super happy with these shorts!!! Wore them on a full day at the theme park. Stayed in place and did not ride up. No pinching or constricting. The material is buttery soft and the blue is so vibrant and pretty!! Don’t show every bump and imperfection, but does show some. It’s not totally smoothing. Very work out friendly, heat friendly, running errands friendly. Would definitely recommend and plan to buy other colors. Comfy waist band as well.

Excellent Work-out & Biking Short
Special Size: 7" Inseam without Pockets, Size: Small, Color: Ocean Blue
I love these biker shorts. They have just the right amount of lycra and they are super soft. They are true to size, and they fit perfectly on my 5'2", 125-pound frame. I purchased them for use in bike riding, and I am very pleased with the fit and stretch. The inseam length is perfect for bike riding, and the legs don't ride up my thigh. The only con to all the pros is there isn't a phone pocket. I ride my bike around town, and I would have liked to have a pocket for my phone when going inside a store. These shorts are well worth the price. I purchased three different colors and love them all. I would definitely purchase this item again.
