Vertex 8 cyl cap - OPENED for Suppression Wire
Then the trouble is getting it to fit in the old style Vertex cap! It's pretty much IMPOSSIBLE to get the larger wire into the tiny stock holes in the cap.
So, we built a special fixture for the caps so that we can machine them in our CNC milling machine. We open the holes in the cap up to fit the Taylor racing suppression core wire we carry. FINALLY, IT FITS!
We have a special set of wires just for you: SUPPRESSION wire set for the Vertex
The Taylor Thundervolt 50 wire is just a little over 8mm and it fits nicely after machining. The larger 8.5mm MSD wire will NOT FIT in these caps. If the caps are machined out that far, they are extremely thin in certain places and can break. When machined out to fit the Taylor wire, no problems. And your tach and shift-light will love you.
