Mine is all fitted and running nicely.
I would recommend fitting the 60degree bend to the plenum first, making sure it gets around a bosch sensor and the header tank for the coolant. Do this before you go fitting the sensors and cutting the holes for the Tee pieces. Had to buy another bend after this mistake.
Also the pipe which recycles excess oil pressure will need extending slightly in order to fit. However, good old central heating copper tube fits inside perfectly, simply cut the tube in half - and insert a short length to make up the shortfall.
Keep the 90 degree bend coming up from the air box quite short in height, but quite long in reach, this makes the angle to your 60 degree bend very neat.
Delighted with the result, my ECU is still learning, but revs are a lot lower when idling.
