Overview:

For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD Flying Magnet Crank Trigger system does exactly that by using four magnets embedded in an aluminum wheel. Although similar in appearance to other crank triggers, the MSD Flying Magnet design works on a different principle. Most crank triggers have a wheel, with steel studs sticking out, bolted to the harmonic balancer. As the crankshaft turns, the studs pass by a stationary magnetic pick-up, triggering the ignition. This pick-up can be triggered by other bolts, debris or even vibrations which will cause a loss of power or engine damage. The MSD Flying Magnet Crank Trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This ""flying magnet"" design produces accurate trigger signals and the non-magnetic pick-up cannot be false triggered. Each Flying Magnet Crank Trigger includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver's side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The CNC-machined aluminum bracket securely holds the pick-up in place and is slotted to provide a wide range of timing adjustment. Spacers are included so you can mount the bracket on engines with standard motor mounts or engines with a .25"" motor plate. These systems will trigger MSD 6, 7 and 8 Series Ignitions and all MSD Timing Accessories.

    Works well!
    Scent Name: Berry, Size: 40 Count (Pack of 1)
    Nice flavor. They don’t melt real fast like the ACT I’ve been using. They are smaller than I thought and I didn’t think they would last as long as they do. Keeping my mouth/throat moist as they said. I like the way they stick to your mouth and you don’t have to worry about swolling accidentally!

    Scent Name: Berry, Size: 40 Count (Pack of 1)
    Not as strong a flavor as mints. Berry flavor is the best. I take one per night. Does the job.

    Terrible.
    Scent Name: Berry, Size: 40 Count (Pack of 1)
    These do not work at all.. I used two at night and they just dissolve and my mouth is still super dry. I tried one during the day just to see and they do not help you salivate at all really. Definitely would recommend trying something else.

    Xylimelts
    Scent Name: Berry, Size: 40 Count (Pack of 1)
    "Xylimelts - I have dry mouth from what I thought was a new medication. I stopped the medication about two weeks ago and it has not improved. I am continuing to use these until I follow up with my doctor. At first I tried these using one disk and it did not seem to work. I tried them again using two and it works a lot better. So, I now use these two disks at a time. If I use them at night, they seem to last about 4 hours. If i use them during the day, they last about 30 minutes. The effects do not last all that long during the day but I do also use Act lemon lozenges. The package says that you can put them on the gums but I put them on the roof of my mouth. I have had no issues getting any of them to stick. Flavors - At my local stores the only flavor is mint. It is way too strong. Using the mint ones would irritate my mouth after a while. Unfortunately, that seems to be the only flavor that most dry mouth products are.....mint. So my quest began to locate products that are not mint. I found these here on Amazon. They come in multiple flavors. Here is my breakdown of the flavors and my thoughts on each. Mild mint (4*) - Better than the regular mint but still mint. It is as described and the mint is not as strong. Slightly Sweet (5*) - Probably my favorite alternative to the mint. They are exactly as described. The have a slightly sweet flavor. It is not overwhelming. Berry (5*) - This was a nice change. It again is a slight berry flavor. Not overpowering or overwhelming. Cinnamon (1*) - This is probably my least favorite. The flavor was ok (it tastes like a very mild fireball) but it didn't seem to lubricate very much and after it was gone it felt like my mouth was drier than before. Orange (4*) - It has a pleasant orange flavor. Sensitive/unflavored - I have not tried this one yet. I probably will not. The reviews of the change in adhesive makes me leary to try it."

    Mostly works, but..........
    I use these at night for sleeping with a CPAP. I am a mouth breather, so my CPAP mask is a full face mask, thus there is constant airflow going into my mouth all night long. While these tablets do help with reducing dry mouth, they only last about 4-5 hrs before they fully dissolve - which does not get me through a full night of sleep. Using two tablets instead of one only gives me roughly one additional hour. If you wear a CPAP mask, you also need to be careful of exactly where you place the tablets, because it will be quite uncomfortable if you mask ends up pressing on the tablet. If the tablet does not adhere well upon initial placement, you pretty much need to fully dry the tablet before re-attempting placement. If the brown side is already wet when you place it against your gums, there is a much higher chance of it just sliding off, instead of sticking. Overall, while not completely eliminating the issue, they do at least reduce the dry mouth problem during sleep.
