    Default M70/M73 ignition wire sets L+R NEW

    made on special order and available now. Presently have them in black or blue colour available. Consist of all 12 ignition wires with plugs between plugs and distributors, and 2 wires with plugs between ignition coils and distributors. Blue set plugs are also black, same as the black set plugs.

    Not included:
    -bracket/cable channel, to be used from existing one engine
    -2 donuts/speed sensors (can be delivered at extra price new, either BMW OEM, or made by FACET, whatever you like). But usually the old donuts are re-used. Instructions to refit them, see inside link. Longer delivery time for this, as no stock presently for donuts.
    -no marten protection on the ignition wires (that was also optional on the OEM), cable 'rubber' and plug 'rubber' made of silicon material. So much softer than the OEM ones.
    Plugs are woodscrew type connections, easier to use than the OEM metal bush connections which sometimes fail.

    In case of interest send me a PM with shipping details.

    Shogun's Plug Wire Install Write Up (written by James, his car:1992 750iL)

    Installing Shogun's plug wires.

    I did not take pics, sorry. I am the impatient type and taking pics takes too long plus I don't wear gloves so I would have to wash my hand every time to pick up my camera. So hopefully my write up will be good enough to understand and if you have questions please let me know.

    This will be in a semi bullet/step style write up with notes, I will not bore you will some hurdle details I needed to overcome just the fixes/work arounds.

    First off these wires are excellent quality!

    The "wood" screw type connector is traditional type i.e. if you are looking at the top of the screw it is clockwise on counter clockwise off. Righty tighty lefty loosey.

    I laid out all wires to get the groupings done and label all the wires with 1-12 by the distributor boot.

    I Installed the CI sensor on 6 and 12 wires. 1st hurdle, I could NOT unscrew the plug ends because the rubber boot was so tight and I could not verify removal unscrew direction at this point. I just pulled the boot off with force hoping it would not damage anything else. Once that was done and the plug end was cleaned of any remaining wire in the screw portion I was able to verify righty tighty lefty loosey. Installed CI Sensors. 2nd hurdle could not screw the ends back on due the rubber boot being so tight. So I removed the actual plug by prying it out. Once out I slid the boot over the wire and down a few inches then screwed the ends on and slid the boot over the ends. Be careful push/pull only on the plug itself (NOT THE WIRE) when doing this so you don't pull the wire out of the plug again. I used some dielectric grease to help.

    Installed the wires into the guides, this took some playing around to get the wires to lay nicely.

    Installed wires and guides into car, unplugged at this point.

    ** These wires do not self align to the spark plugs or the distributor cap plugs like the OEM wires/boots, more on this at end of write up**

    Started to plug wires on to plugs. 3rd hurdle, I could not get the boots to plug onto the spark plugs, see note above. This took a while but the fix was to wiggle the plug boot around till it lined up on the spark plug and push hard. Once I realized this it was not a big deal.

    Started to plug wires to distributor. 4th hurdle, once again you have to wiggle the boots around to get them to plug in.

    Plugged CI sensors in

    After install was done just a quick double to make sure I had correct order on distributor cap I started it up.

    **So more on the wire plugs. I cannot say for the spark plug side of the wire why it did not self align but the distributor side I can say it is because the portion of the plug that goes into the distributor is thinner then the OEM plugs so they will not self align. I am assuming that it is a similar issue with the spark plug side being that the boot is a bit too wide to align on spark plug. Either way you HAVE to wiggle the boot around till it seats properly and then push, this took some time the first go around. If/when I have to do it again it will be much faster.**

    Install time: 3hours, once again it would have been about 1-2 hours if I had the forehand knowledge of the screw direction and the alignment.
