Our Hellcat/Redeye/Demon AOS Kit is brand new for the holiday 2019 season and is the most solid mount HEMI in your LX/LC/LA platform vehicle.


It features all the great features of our base Air/Oil Separator plus the blower-specific billet aluminum bracket and factory oem fittings to connect your hoses to your engine, plug-and-play. There is not a better-fitting, better-performing Air/Oil Separator on the market.


Available in Satin (silver) or Black and kit comes with:


  • Air/Oil Separator with 90-degree Steel Bracket
  • Full set of spare O-Rings and Stainless Fasteners
  • Blower Bracket and hardware
  • 2 x 1/2" Barbed Fittings
  • 2 x Port Plugs
  • Inlet and outlet side factory elbow fittings


  • We do not include the hose needed to connect this unit to the vehicle in our kit. The hose is available at nearly any Auto Parts store and we can't get it any less expensively than you can.

    poorly engineered mount

    Posted by Dwayne Morales on Oct 12th 2020

    This item was a hassle to install on a 2019 charger HC. The screws provided are too long, I had to add washers. The allen screw provided is a waste, there is no way this screw entered behind the mount. They tried to be different from other brands and I will rate this item the worse catch can to install. No instructions provided or a link of a how to install.

    HHP NOTE: Dwayne, AAD listened and they've redesigned the bracket and are using different bolts now in this kit. The new design addresses the exact issues you had. You'll be very happy with the redesign when you get it!
