Overview:

Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference! In a single 12 inch length of Super Conductor Wire there is only 40 - 50 ohms of resistance! That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it's great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) "choke". This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. The MSD's 8.5mm spark plug terminals feature Dual Crimp terminals. As the name implies, the terminals feature two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor.

    Too firm throughout, but no support
    Size: 57 Inch, Color: Light Yellow
    I like the feel of the fabric but it's honestly not comfortable for me. The stuffing makes the pillow way too firm and I wake up with sore neck muscles. I do appreciate the body length, (I am 5'3) and it's comfortable for a little while, but not for the whole night. Especially because I have to get up multiple times to use the bathroom, and this pillow just gets in the way. I decided to just use three different pillows for my head, my legs and my arms/back at all different firmness so I get the support I need. If you are able to deal with the firmness of the pillow throughout, this might be a good option for you. I also ordered the cooling option and this does not help keep me cool at night. Even with the AC on and the fan running. It sleeps hot. I ended up storing it back in its vacuumed sealed bag and put it away.

    Who Says Pregnancy Pillows Are Just for Pregnancy?
    Size: 57 Inch, Color: Light Grey, Size: 57 Inch, Color: Light Grey
    I bought this pregnancy pillow even though I’m not pregnant, and I have zero regrets! This thing is incredibly comfortable and provides support in all the right places. Whether I’m sleeping, reading, listening to an audiobook, or just relaxing in bed, it helps me get comfortable and stay comfortable. I love being able to hug one side while supporting my back with the other. It feels like being surrounded by pillows without having to constantly rearrange them throughout the night. The only downside is that it takes up a decent amount of bed space, but honestly, that’s a sacrifice I’m willing to make. My family may disagree. 😆 If you’re considering this pillow but aren’t pregnant, don’t let the name stop you. Comfort is for everyone!

    Comfortable, firm, great for positional sleep therapy
    Color: Cool Grey, Size: 24x24x12 inch
    This is just what I needed to breathe better in my sleep, my doctor recommended a pillow like this for sleep apnea symptoms. I have an upcoming surgery too, so i'm glad I was able to test it out a week prior and see how it can help me prop up in bed. Feeling better about my upcoming recovery knowing i'll have this great pillow to support me!

    Literally perfect and exactly what I needed!
    Color: Cool Grey, Size: 24x24x12 inch
    I can't recommend this enough! It was exactly what i was looking for! I have an annoying habit of researching everything for months before I purchase something that will get used this often. I finally decided on this one and I was very pleasantly surprised. I needed a wedge pillow to put at my back while sitting in bed. Mostly for when I'm working on my laptop. This one was the perfect height and perfect fit for me.I'm a female that is 5'4 and weigh about 117pds. I wanted something firm enough to support my back, and this most certainly does! It had a very pleasant appearance with the light gray sides. It has a removable cover I can take off and wash when needed. It's portable enough to move from room to room, also works great on my couch and it has amazing versatility. It can also be used as a pillow for someone that might need to sleep at a slight incline. It also works if you need to prop your legs up. It came vacuum packed. Once opened It said to let is sit for at least 24-48 hrs to give it time to properly inflate. For me, It plumped right up immediately! Again, from someone that does her research, if your looking for something like this at a reasonable price, this is it!

    It was worth every cent
    Color: Cool Grey, Size: 24x24x12 inch
    I have BPPV. It's a condition where tiny ear crystals come out of place and move within your ear canals - this fools your brain into thinking you're in motion, causing severe dizziness. The most common treatment is the Epley Maneuver, and that actually helps a lot. However, I was going through a period where every single day I'd wake up with severe dizziness. Even if I managed to do the Epley Maneuver and it worked, the entire rest of the day would be ruined because I'd still feel generally unwell and nauseous. I ended up getting a book about BPPV and the author strongly recommended sleeping at at least a 30 degree angle. So, that's why I ended up buying this wedge pillow... I started using it April 26 and today is May 17. Since I began using it as a pillow, I have not woke up dizzy again. That is so huge! It may be that sleeping at a 30 degree angle deserves 5 Stars but thought I'd give this pillow 5 Stars too, as it's been a great experience. If you suffer from this, here's how the angle should be...If you lay your head on a pillow and open your eyes, you should not be looking at the ceiling. With the right angle, you should be looking at where the wall meets the ceiling. If so, you know you're at the right angle. As far as pillow itself, I'd say the pillow case fabric is of average quality. Not really remarkable in any way. It seems decent. Good value for the price. The inside is firm (which is just what I needed) but comfortable, and I tend to not move around much the entire night. I like this very much and if it does start wearing out, I'll definitely come back here and buy another. Would recommend.
