MSD 8.5mm Super Conductor spark plug wire sets feature a special helically wound core that has just 40-50 ohms of resistance per footbut with an RFI suppression equal to a 1,500 ohm wire. In fact, each foot of finished wire includes 40 ft. of tightly wound copper for superior conductivity. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference "choke." This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. A tough, 8.5mm synthetic/silicone jacket over an extra-heavy glass braid and dielectric insulator keeps the current guided to the plugs. Underneath the high-temperature boots, dual crimp stainless steel terminals feature snap-locks to ensure a secure fit. Each set comes with clip-on cylinder markers for easy identification. MSD's 8.5mm Super Conductor wire sets are available in custom or universal-fit applications.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.
