How did you mount the bracket for the two wiring loom connectors since it's not in the same position as with the 964 coils? (Lying flat instead of vertical)

hepkat63

anyone have a part number for the 993 HT leads please? finding hard to locate some (only to pinch the ends from them !!)

Silvertarga

The lead is 993.602.060.07

As noted above the ends are part 928 602 557 00

I'm no EE, but you might want to compare specs between the coils before swapping them over. With too much dwell time they're not going to last very long.

tdiquattro

Just mounted them over the existing threaded stud, just add a plastic nut to hold in place, the heat sink is not altered and will do its job.

cheers

-nick..point taken but it cant be any worse than the Silver Bosch coils!!

Duck

Any update from those that have made the switch?

tdiquattro

All good, several hundred hard miles and perfect.

Duck

Thanks for the update. I have this set up all ready once I get back my engine from shop.

Duck

Has anyone had problems installing the 993 connectors 928 602 557 00? I bought brand new ones, but cannot seem to get them connected. I can reinstall the old end connectors easily, but the 993 just will not spin on.

Silvertarga

New connectors are a tight fit, try spraying some silicone on them to lube or get the new connectors warm so the rubber is flexible

Duck

Might try warm them up a little. Already tried the silicone, but cannot get them to connect. Very easy with the 964 plugs.

Duck

Got one connected. Will try the other one later. Hope it works well. Definitely like how the coils fit and will be nice to no longer use those silver coils.
