My ultra set (P/N 51055 ) of wires came with Eight 8mm wires and a coil wire. Not included in my ultra set are any wire separators and any silicone lube. Possibility the straight boots were short enough to not require silicone. The wires looked to be well made. The description needed to include that the 90 degree connection to the distributor requires a distributor cap with male connections exposed on top of the cap. My distributor cap has female contacts on the inside that require the wires to have a male connection. Also for my application some of the wires would have been too short if they had the right male connection to the distributor cap.
