CSF's strategic relationship with PWR has allowed the inclusion of this core, which is unlike any other available in the performance aftermarket.

The most important feature of the CSF by PWR RS6/RS7 Intercooler System is the Formula-1 grade intercooler core. CSF's strategic relationship with PWR has allowed the inclusion of this core, which is unlike any other available in the performance aftermarket. Featuring two rows of rolled cooling tubes with inner fins, these cores make for the most efficient intercoolers available. Because of this, they are able to eliminate heat soak and lower IATs much more efficiently than traditional Bar & Plate or Tube & Fin designs. This gives us maximum performance for extended periods of time under demanding driving conditions and for vehicles with increased power levels through modifications and tuning. As with our other products produced through our PWR partnership, our new RS6/RS7 Intercoolers feature 100% TIG-welded machined billet aluminum end tanks vs. the OEM crimped cast aluminum end tanks. This feature is not only aesthetically pleasing, but is also stronger for longevity and durability on high-performance vehicles. The CNC machined billet end tanks are ready to withstand increased boost pressures from higher performance tunes, as well as upgraded turbochargers.This Part Fits:

Fast Working
Size: 100 Count (Pack of 1), Style: Melatonin 1mg
I have a hard time staying asleep. I took this product the first day and slept very well. I would recommend this highly. Dissolves Faunder the tongue and works sooner than capsules or pills.

Melatonin by Superior Source

I've bought this melatonin repeatedly for years. It works gently and naturally to help me drift off to sleep and wake rested and ready for the day. I always get the smallest dose 1 mg

So far it does help me with becoming drowsy for sleep
Size: 100 Count (Pack of 1), Style: Melatonin 1mg
So far this melatonin helps with making me drowsy, but I still take 1/2 a prescribed sleeping pill with it. Normally, within a half hour I am sleepy. I have not tried taking it by itself yet. I am a petite build, so I think my size factors in to how well it works for me. Flavor is okay. Easy to take melting it under my tongue. Price is okay. I like that it is sublingual and limited added ingredients. I don't usually take chamomile due to being sensitive to it in the past, but seems to be okay in this pill. It also seems to help me with staying asleep for a longer period of time.
