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. The MSD's 8.5mm spark plug terminals feature Dual Crimp terminals.

    not recommended
    Color: Nordic Blue/Space Grey, Style: Miele Guard L1
    I would not recommend this vacuum. The hose does not swivel at the base so its in a knot.The handle does not have the power switch, not convenient.When you pull the power cord out the whole vacuum moves.For the price it feels cheap.

    A Game Changer for Pet Hair Cleanup!
    Color: Black, Size: L40 Ultra Gen 2, Color: Black, Size: L40 Ultra Gen 2
    This robot vacuum and mop combo has been fabulous. We have a golden retriever that constantly keeps us on our toes with shedding and cleaning, but this has definitely helped cut down the time spent cleaning every day. The suction power is impressive, it does a great job on pet hair, and the mop feature is a huge bonus. I also love the self-emptying dock and app control — it makes everything so convenient. Definitely worth it for pet owners!

    Pretty solid upgrade from my old robot vacuum
    Color: White, Size: L40 Ultra Gen 2
    I bought this robot vacuum to replace an older one I had, and after using it for about a month, I’d say it’s been working pretty well overall. When I first got it, one thing I noticed was that it’s a bit on the larger side, so it does take up some space. Setup was pretty simple though, and once it got going, it just kind of did its thing without me having to babysit it. The suction is definitely strong enough for everyday dust and pet hair. I’ve used it on both hard floors and carpet, and it handled both without any issues. The mopping feature is new to me since my old robot didn’t have it. I’d say the results are about what I expected, it’s great for maintaining daily cleanliness, but for tougher stains it’s still not quite the same as scrubbing by hand. For regular upkeep though, it does the job just fine. The corner cleaning has actually been a nice surprise. It will go under furniture and use the side brush to get dust out of corners, which used to be something I had to do myself. Now I barely have to think about it. So far, both my family and I are pretty happy with it. We haven’t run into any major issues. It does a good job avoiding objects around the house, although there were a couple of times where its path looked a bit random to me. Still, most of the time it’s quietly doing its job and saving us a lot of time on cleaning.

    Powerful and convenient
    Color: Black, Size: L40 Ultra Gen 2
    Really happy with this robot vacuum so far. The suction is strong and it picks up dust and pet hair easily. Mapping is accurate, and it cleans efficiently without missing spots. The self-emptying dock is super convenient and saves a lot of time. Mopping works well for light cleaning too.Overall, a great upgrade and definitely worth it.

    Better Than Expected
    Color: Black, Size: L40 Ultra Gen 2
    Been using the Dreame L40 Ultra Gen 2 for a few days now and honestly it’s better than I expected.The suction power is strong, especially for dust, hair, and small debris. The mopping performance is also surprisingly good compared to older robot vacuums.What I like most is the automation — auto-emptying, auto mop washing, and auto drying make daily cleaning much easier.Navigation is smart and smooth, and it rarely bumps into things.The only downside is the dirty water tank needs regular cleaning, and thick carpets still clean better with a traditional vacuum.Overall, it’s a great upgrade for busy people who want to keep their home clean without spending too much time on it.
