Just do what i did, get two heated jets in the two standard holes, and get two normal jets from the breakers, then they just fit into the other oles in the bonnet, near the middle, then you have 8 jets. It works better than he MK4 i think! You also have to two of the three way connectors for the tubing. Then it all looks standard, cos it kinda is.
You want a picture, anyone?
