I bought this a while back and just recently fitted it. I should have done it sooner because I needed to flush out my clutch fluid. If you haven't seen this, it replaces the bleed screw on the slave cylinder and allows for very easy bleeding. It really is a pain in the butt to bleed the clutch when you have the original exhaust with the crossover pipe. It's still a pain to bleed it even if you have a new dual exhaust. I guess I put it off because it I knew it was going to be a pain to install. However, once it was fitted, it's so easy to bleed the clutch. Now, I wouldn't hesitate to add new fluid every year (I know it's not required)! Anyone with a manual gearbox should consider getting one of these. It's not fun having to kneel on the engine to see what you're doing down where the slave cylinder is.
