Great little mod!
Install was fairly easy. Instructions tell you to use the bleeder **** on the slave cylinder, but that left some air in the system so I actually used the **** at the reservoir to ensure I got all air out.
It feels SO much better than stock. I have an aftermarket clutch with slightly firmer pressure, but this mod actually lightened the clutch pedal feel while still making it more intuitive, with crisp and fluid engagement. The engagement feels more directly "mechanical" now, as opposed so some kind of remote pressurized system. You get better feedback from the pedal, and it is easy to shift smoothly, even while being aggressive. I honestly think I would've learned to drive stick better if I never had the original delay valve in there, I wish Subaru would remove it from the factory. Highly recommend this part.
