Mishimoto is the Best 180 T stat. I have this installed on My Hellcat now.
Mishimoto 180 Degree Racing Thermostat & Gasket for Gen III Hemi 5.7/6.1/6.2/6.4L - MMTS-JED-06L
Your high-performance 5.7L, 6.1L, 6.4L or 6.2L HEMI needs a reliable and effective cooling system to extend engine life and perform at its absolute best. Mishimoto is proud to introduce a racing thermostat specifically designed for the 5.7L/6.1L Hemi engine. Mishimoto racing thermostats promote greater cooling efficiency by significantly decreasing high engine temperatures. Once the engine is fully warmed up, the Mishimoto low-temperature racing thermostat will open at a lower temperature (180°) compared to standard thermostats (203°). This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Whether your vehicle is stock, cammed, or blown, the Mishimoto racing thermostat will provide superior cooling efficiency to keep your vehicle on the road and out of the shop. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty
*Does not Work on 6.4L Rams

My husband back in 2015 Popped a Metco Breather on our Hellcats, and they are still there today.
Metco is also a supporting vendor on here.https://www.hellcat.org/forums/metco-motorsports.23/
Metco Valve Cover Breather (2015 Hellcat Vehicles) - MBR0019
This breather installs as a direct replacement for the OEM oil fill cap, and absolutely no modifications are required. The precision-machined helix in the bottom of the billet stand fits tightly into the fill tube, and the seal is maintained by the included o-ring.
In supercharged applications, combustion pressures invariably find their way into the crank case, and this pressure contributes to pumping losses, elevated oil temps, and premature failure of engine seals. The breather serves as a high-flow vent to allow any pressure that builds to easily vent into the atmosphere.
This breather is fitted with our proprietary APV one-way check valve, so while internal pressures can pass through, outside air cannot be drawn through the breather and into the inlet tract of the engine. Your engine tune will not be affected by the installation of this breather.
Like all Metco breathers, this unit is CNC-machined from 6061 aluminum, and micro-finished on the exterior surface. The filter is a high-quality reusable unit manufactured in the USA by S & B filters.
Total installed height is less than 3". This breather may not be legal in all states.
For earlier Gen III Hemi applications using a screw-in style oil cap, please see the MBR0012 breather listed elsewhere in this section.
