CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your 991.2 911 / 718 running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.This Part Fits:

Good quality and adjustable comfort
Size: Queen (Adjustable Foam)
Well-constructed and packed with lots of foam pieces. As received, the pillow is firm and well stuffed. I would up removing a good amount of stuffing for a custom fit -- as recommended by the pillow maker. Now, the pillow is extremely comfortable.
Due to being able to customize the fill and making this pillow comfortable to my sleeping style, I am happy with this purchase and would recommend its purchase.

I like it
Size: Queen (Adjustable Foam)
I have been trying to find the "perfect" pillow. I am not sure if this would count as the perfect pillow, but it is better than my previous pillow. I have not been waking up with a stiff neck and soreness across my shoulders. It is more firm than I thought it would be. But so far, so good.

Decent firm pillow
Size: Queen (Adjustable Foam)
I've been using the shredded foam pillow since January. At first it was too packed/firm, so I had to remove some of the stuffing from mine. When fully full, it is a chore to get it in/out of our standard pillow cases.
Over time, the pillow has developed a divot from where my head rests the most, so I'll need to fully remove/fluff/reinsert the foam to get it back into shape. Overall, I find the comfort of this pillow just okay. It absorbs your head heat even in the winter, so if you prefer a cool pillow, I don't recommend it. It does seem to be a good quality pillow otherwise. I expect I'll be able to use this one for a few years without it falling apart. It doesn't smell bad either.
My husband really likes the pillow, but I've also seen him sleep comfortably on very old pillows that have turned into pancakes... so do with that information what you will.

Best Pillow ever
Size: Queen (Adjustable Foam)
I am in love with this pillow. I have such a hard time finding a pillow that works for me because they are usually to big or too flat. This pillow is right where I need it to be. It is soooo comfortable. My neck has no pain anymore. The quality is high as well. No bad stitching. The stuffing is evenly distributed and the pillow is so soft sometimes I don't even want to use a pillow case but I do haha. Definitely worth the money.
