Overview:

MSD is excited to announce the next generation of 6-Series ignition controls - the 6AL-2! The ignition control combines a new housing, new digital controls and more power in a sleek package. Inside the new cast aluminum housing you'll find an advanced micro-controller that manages the built-in two step rev-limiter. The spark output of the new box has been turned up to 535 volts of primary voltage with spark energy reaching up to 135 millijoules! The multiple sparks of the 6AL-2 burn in the cylinder for 20 degrees of crankshaft rotation to ensure complete combustion. Two more great features are the rev limits! There are two rev limiters; one for high end overrev protection and another you can activate off a clutch or transbrake to set a launch limit. This feature will help your car blast off the starting line! Adjustments are made via four rotary dials for 100 rpm increment control! The all new capacitive discharge ignition will easily connect to nearly any 12-volt negative ground distributor system.

    Scent and application does not irritate my very sensitive lungs and skin
    I am having excellent luck with this sunblock! I have sensitive skin and am extremely sensitive to some aerosol and scented products. This has not been an issue with me in any way. We do apply this outside for more ventilation. I have not used this on small children. This has primarily been tried by adults in my household. It’s super easy to apply, not oily, and so far is providing sun protection. I have not used this and then entered water. Our use has been for just everyday running around. It has not irritated anyone’s skin and no one has been burned by the sun- so gonna say it’s a win. This is very likely my new brand. I will update this review over the summer with how it holds up at the beach and pool. It’s doing a great job for basic outside recreation and play

    Nice refreshing sunscreen
    Great spray sunscreen. Don't even notice any difference between this organic sunscreen and regular sunscreen. It sprays nice and evenly and provides good protection for a reasonable time. I've used this during a number of workouts out in the sun, sweating, for a few hours at a time. It sprays pretty lightly on, and stays on. Once it sprays on, while it feels light, you do feel it (like a little sticky on your skin), same as any other sunscreen really though.
