The K-Tuned Clutch Master Cylinder Upgrade Kit was designed to completely replace the original factory cylinder and offer real time clutch engagement to support faster shifting. We have put together a complete bolt-on kit that includes a direct replacement CMC, our high pressure 3AN clutch line, plus all of the necessary fittings needed for installation. The factory clutch fluid reservoir is reused and connected the same way it was in stock form. The only thing we suggest is checking out your slave cylinder on the trans to confirm it is leak free. Aside from that, installation is pretty simple, install the parts and bleed the system using some new clutch fluid.

The 2002-2006 RSX and the 2006-2011 8th Gen Civic Si all have a known issue with their factory clutch master cylinders (CMC). If you look at the CMC on these cars more closely, you'll notice that all of these models have a triangular shaped feedback plate positioned at the very end of the cylinder. This plate is basically a secondary valve that was designed to slow down the clutch engagement and reduce shock to the clutch itself and the surrounding drivetrain parts. This setup might be perfectly fine for people that just drive their cars for simple daily use, but the delayed engagement can cause wear to the synchros and possibly even the gears on performance applications. The reason is fairly simple, the factory CMC delays the clutch operation, so it does not open fast enough to keep up with a fast shift. This means that pressure is being applied to the transmission synchros during the shift, before they are ready for the actual gear change.

Great gift!
Color: Light Blue
I bought these for teacher appreciation gifts and the recipients loved them! The light blue ones just add a pop of color and I’ve been told they keep their coffee warm ALL day. What a sweet treat for deserving educators. I plan on buying one for my desk!

Does the job, wish it had some safety features
Color: Black
Good value for the price, and it definitely keeps your coffee warm. I do wish it had a safety feature where it could turn off on its own, or a less sensitive on/off button. It goes on easily and gets very hot, so it can be dangerous with little kids.

FINALLY able to enjoy my morning coffee without reheating!!!!
Color: Black
Since this mug warmer arrived, I have finally been able to enjoy a relaxing cup of morning coffee. Value and quality are on point. This warmer keeps my coffee warm to the last drop. The cord is long enough to reach an outlet near the end table, easy and simple operation (tap on, tap to lower temp up to two times then final tap off). Auto shut off after 4 hours which I have not used yet as I always unplug my unit after each use, however it is nice to know that is an option. Just one suggestion, Using a mug lid with unit also helps keep the hot beverage at a consistant temp. I LOVE IT and wish I ordered one sooner.

Perfect
Color: Light Blue
For me this coffee warmer is perfect. The disk sides are just right. High enough for a good fit, but not so high you risk sloshing your beverage. The color (blue) is exactly as displayed. Works great and a very good price.

Works only moderately well to keep coffee hot
Color: Light Blue
Not quite what I expected. Although the base heats up as described, it does not keep my coffee as warm as I would expect at the highest temperature.
