CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your B5 S4 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.The CSF B5 S4 radiator is a true "Drop-in fit" design requiring no modifications to install. OE style brackets are all CNC machined and welded for the best durability possible. Inlet/Outlet connections are designed to match the OE connections so you can reuse OEM hoses or aftermarket. Trust the cooling experts at CSF for the best performing, highest-quality, and most reliable radiators.

Tasty and Effective
Size: 1.45 Pound (Pack of 1)
I don't care for the orange flavored fiber at all, but this tastes good. Normally I get unflavored and add crystal light, so this saves me some effort. The only drawback is that I can't concentrate or dilute the fiber per ounce as much, since that changes the flavor. Personally I find 2 teaspoons per 8oz to be the max dilution I can handle, making it not too flavorful to be chugged while still being just flavorful enough to help me overcome the somewhat odd texture of the fiber. It's best to add this to mildly cold water, mix well (I shake it vigorously in a water bottle), and drink immediately. If it's mixed well in cooler water at the right dilution and you don't wait too long to drink it, the fiber is almost unnoticeable. From my doctor and my own knowledge as an evolutionary biologist: For those of you who are just starting fiber, it's important to not start with the full dose. Doing so can shock your digestive system and have the opposite of the intended effect. Ramp up from one teaspoon, taking it daily (best in the evening) adding an additional teaspoon each week until you reach 4 teaspoons (a tablespoon, the recommended dose). When used regularly and correctly, daily fiber can be a life changer. Our gut microbiome is an integral part of our digestive system. It evolved with our species, and we need to feed it what it evolved to eat!

Sweet but good.
Size: 1.45 Pound (Pack of 1)
Make sure to buy flavorless fibers as well and blend together with this one at least 50/50 if not 25/75 since it's very flavorful and very sweet with not so healthy sweeteners.

Tell R&D to find a new flavor house, this tastes awful
Size: 1.45 Pound (Pack of 1)
This “berry” flavor tastes astoundingly terrible. It is a wonder to me that this could have passed any product development team. It is like the worst kind of cough medicine mixed with bitter off notes, and it is a very strong flavor, so it is very in your face. The orange original is not great tasting but not bad, you would assume they would only release a new flavor if it was better. They ought to call a flavor house and reformulate this, the technology exists to make this taste good, but wow, this is really unpleasant.

Good flavor
Size: 1.45 Pound (Pack of 1)
Good flavor. I quit drinking Metamucil in the past because I didn't like the orange. I was reluctant to try a different flavor but after reading many positive comments about this one I decided to try it. I was not disappointed. Thank you to all who left positive comments about the Berry flavor.
