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.

    Very nice shelves they look great up and were easy to install. Same color shown in picture. They seem very sturdy on the wall and I love the look of them. They are light weight and a good size just a little plunder 40 inches. Good quality for the price. I'll be buying again.

    Easy to install because of the included instructions. They look great. They’re stable and they included all of the hardware that you will need for installation. I use them for my plants.

    Decent shelf but could be improved upon
    Color: White, Size: 31.5"L x 8"D, Set of 2
    Not bad but could be a little more sturdy. We used longer and a little larger screws to try to make it better and that did help but it still has a little wobble in it. It will serve the purpose for me in my bathroom. They look nice except it would be nice if they would include some of those little covers to go over the screws in the bottom of the shelf so you wouldn’t see them. They really show up on the white shelves.
