CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your Audi Quattro/B1/B2/B3/B4 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 looker but terrible performance
Color: 2-Speed Rechargeable Set with Charging Base
I purchased the product and the base would not attach from the charging module. This is their big selling point. I requested a replacement and sadly the replacement was of the same batch run as the original soo…. Yeah that base would not detach. There are videos showing how easy it is to detach base from charging module. Not theses units. Circle Joy customer service is an @gmail.com. They said base is not designed to be removed frequently. I reminded them the separation feature is their highlighted feature. I was just looking for a base. Circle Joy said no…. If I do not like either unit just return them to Amazon.???? In the meantime, after maybe a dozen grinds, the original unit quit grinding normally and would barely grind at all. I shook it out and it worked again but doesn’t sound right. Two takeaways: 1) Poor product quality. 2) I am sooo done with trying to work with Amazon on replacement items. Save yourself a tone of aggravation and just return the order and reorder if you dare. Otherwise good looking and heavy feel and works great about 10 times. Too bad so sad. Now I have this huge return hassle with Amazon.

Great shakers with convenient dock
Color: Silver, Size: Rechargeable
These are very nice. Work very well. My only complaint is right where I pick them up is the button to turn them in so I’m always accidentally salting the counters lol. Easy to refill. We like the lights. I love that they have a charging dock so they are always fully charged. Very happy with them.

You don’t have to shake it. I love it
Color: Silver, Size: Rechargeable
Different settings from fine to course. It has a light around the bottom where you can see how much you’re using. It stays charged for a while. The quality is great. Well made.
