I took mine out....It's another delay valve, built into the factory clutch line. If you opt for an aftermarket clutch line, you can delete it.
Is it better to delete it? I can't say for sure sure. The difference without it is less noticeable than the improvement from removing the delay valve on the bleeder block.
Going to put it back...but still run the steel line. by design it’s not a delay, once it’s filled with fluids (as the system always is) it’s not going to the slow the system down the same way the delay valve having the bottle neck point.
I didn’t experience any faster or better engagements just a more direct feel of vibrations in the pedal,lol
