Ever since I used the Accel yellow 'universal' wires on my 1980 280ZX back in the 80's, I've never trusted them or any other maker that claims 'universal' fit. The ignition is one of if not the most important component in your engine compartment outside the hunk of steel in the middle.
Best wires made:
I'm not affiliated, but have been a happy customer for several years. I have these on all my Z's as well as my other daily drivers. I prefer the KV series, but if you're on a budget the Electrosports are excellent too.

The 7mm (black) or 8mm (blue) cables
should be fine for a standard unmodified engine, they have very similar
constructions. The KV85 Competition 8.5mm (red) cable is intended for
raced or modified engines - it is not just a bigger diameter cable, the
KV85 8.5mm cable is a different product that has more capabilities for
performance, suppression and heat resistance and can be used on ANY
engine with no problems. The R-100 Racing 10mm (red) cable is the same
basic cable as the 8.5mm and provides the same performance and
suppression, but has a thicker jacket for more extreme temperature
protection and insulation.
The "CN series" cables (which are not available for some applications)
are special versions of our 8.5mm and 10mm cables that provide extra RFI
suppression and are mainly intended for ham radio, CB radio and similar
installations with unusual noise problems; the CN series cables do not
help with most other applications and take longer to ship because CN
series sets are always made to order - they are never in stock.
