The S54 is an incredible feat of engineering. Smooth power delivery, individual throttle bodies, and an 8,000 rpm redline makes for an unforgettable driving experience. As with any BMW, maintenance is key to extending the life of your vehicle and ensuring that you’re getting a driving experience rivaled by very few other vehicles on the road. As many of these vehicles see frequent track time, the team at Mishimoto felt a need to develop a performance aluminium radiator that would not only provide improved durability, but also deliver the efficiency needed for track driving. Our team of engineers developed an extremely dense core on this E46 M3 radiator, that provides a greater number of coolant tubes and a very dense fin composition. This allows for more heat-transfer contact points which results in greater heat exchange and improved efficiency. Additionally, this dense core provides a 32% increase in coolant surface area, a 15% increase in air surface area, and a 25% increase in coolant capacity. All these factors contribute to lower temperatures and greater heat rejection, ideal for those in warm climates and track use. This BMW radiator is designed as a complete bolt-in fit, requiring no modification for fitment with the stock fan and shrouding. Our BMW radiator end tanks are constructed from high-quality aluminium TIG-welded to a 100% brazed aluminium core. Not only does this aid in heat transfer, but it also provides the reliability needed for years of service. Pair this E46 M3 radiator with the Mishimoto BMW E46 M3 Silicone Radiator Hose Kit for added durability over your stock rubber hoses. This BMW radiator is compatible with most aftermarket supercharger kits, providing the cooling power needed for power levels above stock. As with all our BMW parts, the Mishimoto E46 M3 Performance aluminium Radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.

      Not worth it
      Doesn’t really help with redness. Has an oat smell that isn’t very pleasant. Nice moisturizer that isn’t sticky. Not worth the price.

      Calming
      Light weight enough to wear under makeup. Feels nice on Rosecia. Decreases redness.

      Saved my skin barrier!!
      I rarely write reviews, but this product truly deserves it. I have sensitive, dry skin with mild to moderate rosacea that became even more fragile after chemotherapy. While trying to repair my skin barrier, I overdid it with actives and completely wrecked my skin — it was red, raw, burning, and peeling. I turned to ChatGPT for help, and this Avene Cicalfate+ was one of the top recommendations. I started using it about three weeks ago, and wow — the difference is incredible! My skin has healed beautifully. The redness is dramatically reduced, the irritation is gone, and my skin feels soft, smooth, and calm again. The texture is soft and luxurious without being sticky. I love that there’s no noticeable scent, which is perfect for sensitive skin. It arrived well packaged and intact. For the results it delivers, I consider it an amazing value and will absolutely repurchase again and again. If you’re on the fence about trying this, go for it — it truly rescued and revived my skin barrier. This is now a permanent part of my routine and 100% a holy grail product for me!

      Hydrating and Powerful Barrier Repair Serum!💧
      This serum has been life-changing in calming and restoring my skin barrier. It absorbs quickly, feels lightweight, and instantly soothes irritation without feeling greasy. I’ve noticed my skin looks healthier and more balanced after just a few uses. It’s gentle enough for sensitive skin and works especially well when my skin barrier feels compromised. It is also fragrance-free, which I always appreciate! Trust me, it’s well worth the money!

      Works as created.
      Have been using for a few weeks and have noticed 15% improvement in skin and issues. I did notice a difference in the first 24 hours as advertised. It is suggested need a full month I think to see the true results. At 50 I have pre menopausal skin issues- the redness & inflammation, acne, tightness and sensitivity. It is helping in addition to the other Avene skin products that come in the trial box for sensitive or SOS skin box trial size I think ot is called. This has made a difference. It is easy to apply. I use morning and night. It is different from the Cicalfate + Cream. I use that also as needed. I am happy and recommend it. The price is higher than what I spend. But I wanted to try it to see of i need more than just what was in the Avene sensitive skin trial size box they have. My skin is really red and irritated so the $40 for the bottle is was willing to try because it's painful on my face.
