Overview:

The MSD 8.5mm Super Conductor is the ultimate performance wire! Its extremely low-resistance combined with the ability to suppress Electro Magnetic Interference is a combination that defies the common laws of physics. Less resistance means more energy is going to make it to the spark plug to ignite the air/fuel mixture. The Super Conductor uses a copper alloy conductor resulting in less than 50 ohms per foot of wire! This ensures that the most energy possible makes it to the spark plug. By helically winding the conductor around a special core, we are able to produce a highly effective choke to keep the EMI inside the wire and away from other electronics. This combination is encased in a heavy duty sleeve that will withstand abrasion and high temperatures. Cap off each end with our Dual Crimp Terminals and you have the best wire available.

    Immediately yes
    Fill Material: Down Alternative, Size: King Size
    I’m 50 and peri has been kicking my butt lately, so temperature management of my head (as that is the only thing effected by my hot flashes) has been an ever pressing project that I’ve been managing for the last 3-4 years. Hot sleeping has always been one of my curses, so adding perimenopause to the mix has been my own special hell. But Dyson fans, keeping the bedroom window cracked, and lots of all cotton gauze blankets have been imperative for me in the night. Pillows have always been pillowing, they just get warm and flipping them all night long is just finding the least hot version. I even keep 2 pillow choices on the bed while I sleep, and 2 more an arm’s length away on the chest at the bottom of the bed. Silk pillowcases are great for my hair and skin but they don’t keep cool. THESE PILLOWS, complete with the Beckham cooling pillowcases are chef's kiss. They feel like they’ve been in the fridge. Literally. Now do they stay that way, of course not. But they’re cool enough for me to fall asleep. And if I wake, I use the other side. And if I keep another on standby, I am literally finding the cool side of the pillow all night long. I’m not exaggerating either. These pillows are cool WITH the cooling pillowcases. You can’t use a pillow protector though, even if it’s cotton. It will ruin the effect. And you must use the cooling pillowcases. Do both, and you won’t be disappointed.

    Terrible update to a good pillow
    Fill Material: Down Alternative, Size: Queen/Standard Size
    Purchased this as I was looking to replace tbe previous Beckham hotel pillows I had purchased before. When I saw "newer model available" I ordered it. Wish I had just ordered the same ones as before. First off this was only 1 pillow, not the 2 pack. Since I was only replacing 1 pillow I decided to use it. Huge mistake, my neck has been sore almost everyday. The support of this pillow is terrible, even with trying to added and remove some fill to adjust it. Nothing seems to make a difference. Avoid it and order a different model. Wish I had sent it back for a refund when I got it.

    Best Pillow e
    Fill Material: Down Alternative, Size: Queen/Standard Size
    I’ve been using this pillow for 3 months now. It is, hands down, the BEST pillow I’ve ever had. It’s soft and supportive at the same time. As I noted, I’ve been using it for 3 months and it has maintained its loft unlike some of the other types of pillow I’ve tried. Well worth the price and I highly recommend it.

    Just perfect. Well made, No Issues Just one perfect sleep zzzzzzzzzzz😴
    Color: White, Size: Queen (Pack of 2)
    I had down pillows, and foam pillows, and other synthetic pillows etc and some were ok and others were not. I cannot get a great nights sleep if I am constantly having to adjust my pillow during the night. I ordered these pillows as I sleep on my side mostly but sometimes on my back. When they arrived I followed the directions (as they are in a vacuum pack) and only takes a few minutes for them to acclimate. Then put pillow cases on them and off to bed. I had the BEST sleep I have had in YEARS !!!!! The pillows are great. They keep your head comfortable and cool (No Sweating) and super comfortable. The only issue is after a perfect nights sleep, I find I really do not want to get out of bed in the morning..One great thing, is I am retired so I really do not have to get up out of bed until I want to 😴😳. The pillows are well made and feel like expensive down filled pillows but softer. I am VERY satisfied with the pillows. I just wish I would have found these pillows years ago. But now I have them and the perfect sleep that they provide. Dr Dave

    Great sleep
    Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
    Finally found a pillow that is comfortable. Tested about 5 until I found the right one. This is perfect for back and side sleepers. Firm, but soft. Just enough filling and great quality. Will hold up for many years.
