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.

Favorite face wash
Size: Gel Moisturizer, Size: Gel Moisturizer
I use this daily and really love it. It’s super soft and gentle on my skin but still leaves my face feeling clean. The foam is light and satisfying without feeling harsh or drying.

Lightweight, Effective—A Skincare Staple
Size: Gel Moisturizer
I’ve been using the Curology Gel Face Moisturizer every morning and evening and it’s quickly become a go‑to in my routine. The gel texture feels light and cool, absorbs almost instantly, and the clear, scent‑free finish leaves my skin smooth, not sticky or shiny. After a few weeks of use, my combination/acne‑prone skin looks calmer, with less redness and breakouts.
If you’re looking for a daily moisturizer that works under makeup and plays nicely with blemish‑prone skin, this one’s a winner.

Great, will continue to repurchase
Size: Gel Moisturizer
I've been using this for 1.5 years now and continue to repurchase. I have acne prone, sensitive skin and this does not break me out. It's lightweight and feels great!

Has helped my skin and is really nice!
Size: Gel Moisturizer, Size: Gel Moisturizer
I’ve been using the gel, moisturizer, and gentle cleanser together for a little while now, and overall I’m really happy with the set. The cleanser is super gentle and doesn’t leave my skin feeling tight or dry, which is a big plus for me. It feels like it actually cleans without stripping everything away.
The gel and moisturizer both have a really nice, lightweight feel. They absorb quickly and don’t leave any greasy or heavy residue, so they layer well and work great for everyday use. My skin has been feeling softer and more balanced since I started using them.
If I had to point out anything, it’s that the moisturizer might not be quite enough on its own if you have very dry skin, but for normal to slightly dry skin it works really well.
Overall, a solid routine—simple, gentle, and effective. I’d definitely keep using these.
