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.

Loved it
Bought this for my 3 year old son and if it’s perfectly on his toddler, bed would definitely recommend. I love the fluffy and cooling effect. It gives is very soft. It feels amazing. Especially for a toddler very comfy.

Great pillow & Machine Washable
A little on the firm side at first, but it's getting softer with a little use.

Fluff this in the dryer and this is the perfect pillow!
I bought throw pillows from this same brand and was disappointed until I read a tip in the reviews to place them in the dryer on fluff for about 20 minutes. That did the trick and one saved me after a rotator cuff injury. I used it for months to prop my arm up and prevent pain in my shoulder. I loved it so much I decided to see if this brand made a pillow for sleeping and was excited to find they did! This one took two rounds in the dryer on fluff, but I couldn't believe how soft and fluffy it got. I have been getting the best sleep ever since. If you get this pillow, I highly suggest throwing it in the dryer. It makes a huge difference!

Comfortable
This is the fluffiest pillow I have ever bought. I bought it for my 5 year old. He is extremely happy with it and makes him feel like he finally has a big boy pillow that supports him when he sleeps. I might buy one for myself. Defiantly a good purchase.

Fabulous
This is a fabulous pillow. I love it. I recommended wholeheartedly. It is however, large larger than I was expecting. Fortunately, I had a large pillowcase that fits it.
