Hello, I have some suggestions for product development on your V6 distributor caps. I own a '91 GMC Syclone 262ci. V6 Turbo powered truck. I use your V6 cap #8430 on my truck along with your Billet Distributor, Digital 6+ and GM Coil.
The first suggestion is for crossfire vents in your distributor caps which is discribed in the directions for the Digital 6+ ignition:

You do have these on the larger V8 caps and I am jealous!

The second suggestion for your V6 caps is that they have the nice hold down piece for the spark plug wires on top like your V8 caps have.

Thank you,
