PRODUCT INFORMATION
THE ULTIMATE COOLING SOLUTION FOR THE E46 M3
The CSF All-Aluminium Triple-Pass Radiator is the ultimate cooling solution for race and high-performance S54 powered E46 M3, including those with high cooling demands found in forced induction and high-power naturally aspirated engines.
This high-efficiency, all-aluminium radiator features an industry-leading core design with CSF's exclusive B-Tube technology along with an ultra-efficient 6.5mm multi-louvered fin height design.
To further the cooling efficiency, the integrated three-pass flow system guarantees the lowest possible outlet temperatures of any upgraded cooling system available for the platform today. Lab tested using CSF's in-house wind tunnel showed heat rejection results approximately 20% more efficient than the OEM unit - enough to keep coolant temperatures fully stabilized during the most demanding driving and high-ambient-temperature conditions.
Direct replacement for BMW part number 17102228941.

Lightweight bur actually hydrating
Style: 3.38 Fl Oz (Non SPF), Style: 3.38 Fl Oz (Non SPF)
I’ve tried so many moisturizers that either felt greasy, heavy, or just sat on top of my skin, but this La Roche-Posay moisturizer honestly surprised me. It’s super lightweight, absorbs quickly, and leaves my skin feeling soft and hydrated without feeling oily. My face feels smooth and refreshed after using it instead of sticky or coated. It layers really well and doesn’t make my skin feel overloaded. Definitely one of the best moisturizers I’ve used so far.

The Best "Stock Up and Save" Find on the Internet! ⭐⭐⭐⭐⭐
Size: 7.5 Fl Oz (Pack of 6), Scent: Fresh, Size: 7.5 Fl Oz (Pack of 6), Scent: Fresh
If you are tired of overpaying for fancy hand soaps that run out in a week, this Amazon Basics 6-pack of Liquid Hand Soap is the ultimate household hack. It’s simple, effective, and honestly, a total steal.
Why this 6-pack is a total winner:
The "Original Fresh" Scent: It’s exactly what you want in a hand soap—clean, light, and crisp. It’s not overpowering or flowery; it just smells like a freshly cleaned house.
Gentle on Hands: I wash my hands a lot throughout the day, and this formula doesn’t leave my skin feeling dry or cracked. It lathers up perfectly and rinses off clean without that weird "filmy" feeling some cheap soaps have.
The Perfect Size: The 7.5 fl oz bottles are the ideal "goldilocks" size. They fit on every sink—from the tiny powder room to the cluttered kitchen counter—without taking up too much space.
Bulk Convenience: Buying the 6-pack means I’m not constantly adding soap to my grocery list. I keep one at every sink and have backups ready in the pantry. No more "emergency runs" to the store when a bottle runs dry!
The Bottom Line:
You don’t need to spend $5 a bottle for clean hands. This Amazon Basics soap does the job perfectly, smells great, and saves you a ton of money over time. It’s a boring purchase that makes life so much easier.
Final Verdict: 10/10. Great lather, great scent, and even better price. I’m officially a convert!

Good price
Size: 50 Fl Oz (Pack of 1), Scent: Gentle & Mild
Most Amazon basics items are of decent quality and this is no exception.
Nothing fancy just a decent hand soap with typical viscosity that will work in just about any dispenser including automatic dispensers.
Most importantly it does a good job cleaning the hands without leaving your hands all sticky and gooey after washing. Yeah. That really is a thing. I've used hand soaps that after rinsing and drying your left with "gheco hands" like you can pick up a penny with your knuckle.
No chemical or overpowering odor.
One odd thing. The original order came in a box that looked like the Amazon loader threw it into the back of the van from about 50 feet away .... The bottles cap was destroyed and the soap had leaked into the box. Amazon quickly replaced the item with a new bottle no charge and didn't expect me to return the damaged bottle of course. Thing is the second box came in the same condition. Looked like the punter for the Ravens drop kicked it from the 30 into the back of the truck. Luckily the bottle was undamaged this time.
