Yes my DIY one, a 100% perfectly working one, worth it's weight in gold imo.
I had to modify my clutch pedal anyway as my left leg is around 1 1/4" to 1 1/2" shorter than my right, and being long body short leg couldn't easily push the pedal all the way it needed, so it's hydraulic with adjustable height for the pedal AND adjustable stroke, ie it can be set to short stroke or long stroke, as the pivot point on the pedal is movable.
Fitted my new IK27 plugs today, noticed immediate difference first turn of the key, with better idling from cold, I have no iscv, and engine was just happier, and more eager, gapped to 0.6mm.
