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.

    ...and smells good too!
    This lotion seems to be making my crepe skin kinda disappear?? It is so moisturizing & the scent is heavenly. I have used it on my face but it was a little much so I had to put it on while my skin was wet with water. That seemed to do the trick. In Colorado your skin can get super dry & this product seems to replenish softness & moisture.

    Extremely Helpful for Dry, Irritated Skin but Personally Too Heavy for My Face
    Size: 1.35 Fl Oz (Pack of 1), Style: Cicaplast Baume B5 Balm
    This is one of those products that I completely understand the hype around because it truly does work very well for dry, irritated, over-processed, or compromised skin areas. The texture is rich, soothing, and very protective without having a strong fragrance, which I appreciate because heavily scented skincare products usually irritate my skin immediately. I have found this especially helpful for dry patches, irritation from weather, over-exfoliation, and areas where the skin barrier simply feels stressed or uncomfortable. A very small amount goes a long way and the tube itself lasted much longer than I expected. That being said, for me personally this product is simply too heavy to use regularly on my face because I am somewhat breakout-prone with richer creams. While it feels incredibly soothing, I personally prefer using it more selectively on very dry or irritated areas rather than as an all-over facial moisturizer. The packaging arrived perfectly sealed with no leaking or damage during shipping and the product looked exactly as expected upon arrival. For the amount you receive and how little is needed per use, I also think the value is very good compared to many other barrier repair creams. Overall, I absolutely understand why so many people love this product and I do think it is excellent for repairing and protecting irritated skin — I just personally have to be careful about where and how heavily I apply it. #FoundItOnAmazon #AmazonFinds #Skincare #SkinBarrier #LaRochePosay #SensitiveSkin #DrySkin #BeautyFavorites #EverydaySkincare #FrenchPharmacy #SelfCare #LuxeLife

    Excellent skincare product
    Size: 1.35 Fl Oz (Pack of 1), Style: Cicaplast Baume B5 Balm
    I am very happy with this product. I have been using it on irritated and dry skin, and I noticed a big improvement in a short time. It has a smooth texture, absorbs well, and does not feel greasy. It helps calm the skin quickly and restores the skin barrier. I have used it both on my face and on small sensitive areas of the body, and it works very well in both cases. It is definitely a skincare essential that I will always keep in my routine. I highly recommend it.
