CB Performance Black Box on 2023 VMC 2332

Don't waste your money on Iridium plugs. Regular NGK resistor plugs will be fine. My engine runs great with projected tip plugs(DP8EA9), which is what the builder specified. I am now running DPR8EA9 because of EFI.

I'd use what Pat Downs recommends for your engine, but in a resistor plug.

Normally, only one component of the ignition hi-voltage path needs to be resistor. I'd just do the plugs. Makes sense to use resistor plugs for noise/interference with the Black Box.

The vacuum advance/kit isn't going to give you more power. It may make acceleration better/smoother due to fine-tuning the ignition curve. It may also help with fuel economy, running high advance at light load(cruising).

Thanks @DannyP

Do you have a recommendation for wires, assuming my current ones aren’t good enough?

I'm sure your current wires are fine.

Just like all those excessively expensive Monster HDMI cables out there(vs. the cheap ones that come with stuff), if the wires work they're fine.

The way to better spark is two-fold: precision and dwell time. Precision you're working on(black box), dwell time can be increased by increasing the number of coils, which is why everything today is coil-on-plug.

There is a lot of snake-oil in the spark industry: special coils, wires, and gimcrackery plugs.

Thanks again @DannyP

No new wires will save me approximately $100.

As Lee Corso says "Not so fast my friend."  😎I gotta chime in here with related story, the ol'Datsun L24 motor in my 81 Maxima was (240Z thru 84 810/Maxima) running "fine" but when I opened the hood one night with no garage lights around, I saw blue arcs of light all along the plug wires from the distributor to the plugs.   The wires still carried the spark, but I'd say not all the energy was getting to the plug. I replaced with some NGK wires and really could feel the difference in the smoothness of the engine revs and pull.   And no more blue light show under the hood👍👍.  The NGK's cost less than the OE dealer and were considered and aftermarket performance upgrade because of thicker insulation.

Point of the story, check the wires in the dark for poor insulation before assuming they are good.  

FWIW, I do agree with DannyP that there's 1. no need for some super-Monster cable, just a quality OE equivalent is fine & 2. there's a lot of spark snake-oil out there.  (my  $.02)
