You will have a difficult time working with the normal boots for the connectors if you go 10mm.  
I don't know if they make special boots for that size.

I don't remember. I'll guess at the 8mm. They don't seem unusually thick.

Ed and John,

 

Do you guys have the 8.5 or the 10 MM thickness?  Does it matter?

I agree with, John.  I had Magnacore make custom wires for my rotary - cost me around $45 back then.  Have flow for close to 10 years now with the wires with no problem.    I also had the boots in two different colors, one color for leading and one for trailing.

I'd recommend paying the $85.  My magnacore custom made plug leads haven't given me a problem in 8 years.
Any way you can eliminate one possible cause is worth it. One nice thing about Magnacore is that they will make them to specified length with pre-installed connectors. I got mine in 2 colors. Red for leading, Black for trailing.

I had an aftermarket tachometer on my engine test stand that would often read twice the actual rpm.  The engine stand was set up so that the power to each of the four ignition coils could be controlled independently.  The spark plug wires were Mazda OEM.  The behavior of the tach would sometimes be affected by the combination of ignition coils that were active.  In the course of troubleshooting, it was found that the tach would consistently read twice the actual RPM when its input wire was completely disconnected at the tach.  It was concluded that the tach was responding to signals emitted by the spark plug wires and the doubled rpm indication was due to triggering by the ignition signals from both rotors.  Replacing the Mazda spark plug wires with Magnecore wires from the installation in my plane cured the tach errors.  Now, however, checking the ignition timing with an inductive timing light pickup on these wires was difficult whereas it was not a problem with the original wires.

 

It should be noted that the EC2 on the engine stand never gave any indication of having problems when either set of spark plug wires was installed in spite of being physically located closer to the coils and spark plug wires relative to the tach.

Dunno how many people here remember when spark wire was just that: wire.  But it was electrically noisy.  So it got replaced by carbon impregnated fabric, which has rather high resistance (a cheap way to damp the "noise").

Another way to suppress the "noise" is to wrap the wire (many turns, closely spaced) around an insulating core, which creates an inductive impedance, which accomplishes the same goal but readily passes spark current.  AFAIK, "MAGNECORE" was the first to explore this method, but several companies offer a similar product now.  According to some sources, the core material can make a large difference in the inductive effectiveness.  Therefore, I'd recommend
MAGNECORE.
