Dinan High Performance Heat Exchanger - 2019-2025 BMW 330i/M340i/430i/M440i

The OE thermal management system for the B4x/B58 G-chassis BMW and Toyota GR Supra offers an improved formula from prior generations. With a setup where engine coolant is also re-routed through the heat exchanger, the system effectively assists in overall engine cooling as well as charge cooling. However, like its predecessors, it has room for improvement as it can be overwhelmed when the system is taxed aggressively or as power levels are increased. Once overburdened, this results in the undesirable outcome of power being diminished. Avoidance of this unwelcome scenario can be attained though with a Dinan heat exchanger that improves the overall thermal management system so everything runs cooler and more efficiently while being budget friendly.

Features:

  • Average of 8.7? C reduction in charge air temps with a maximum reduction of nearly 12? C over 30 successive WOT pulls
  • General improvement to the efficiency of the thermal management system, inclusive of engine cooling
  • 45mm thick Dinan core vs. 26.75mm thick stock cooler core
  • 68% more cooling surface area and volume than stock
  • Reduces the tendency to heat soak / go in to limp mode
  • Durable bar and plate design that is less susceptible to damage from road debris
  • Pressure tested, 100% TIG welded, Aluminum construction
  • Direct fit replacement with no modifications required

Adorable backpack for a toddler
Color: Flower Pinkish Blue, Style: Toddler-12"h(not Fit Folder)
This is such an adorable backpack! I bought to hold a gift for a 1 year old. Rather than buying a gift bag, I used this backpack. Very cute, seems well made too. Perfect for a little toddler and has perfect space for some of their little books, toys, clothes!

Ideal preschool bag for your princess
Color: Flower Pink, Style: Toddler-12"h(not Fit Folder), Color: Flower Pink, Style: Toddler-12"h(not Fit Folder)
I couldn’t be happier with this toddler backpack! The Mibasies Toddler Backpack for Girls is the perfect size for my little one—lightweight, comfortable, and just right for preschool. The straps are soft and adjustable, so it fits securely without slipping off her shoulders. The design is absolutely adorable and makes her excited to carry it every day. The compartments are well thought out: roomy enough for snacks, a water bottle, and her favorite toy, yet not too bulky for a toddler to manage. The quality feels durable and sturdy, which gives me peace of mind that it will last through daily use. What I love most is how it balances style, practicality, and comfort. My daughter beams with pride wearing it, and I’ve already received compliments from other parents. If you’re looking for a preschool backpack that’s both functional and fun, this one is a winner. Highly recommend!

Durable materials

My oldest daughter used her bag for first grade, and then again starting for second grade. It has shown great quality, all zippers are still in great shape, has all the pockets for folders and small things, still big enough to pack a pair of shoes and clothes in it, and it’s super easy to keep clean. I feel like this was the best value for my money, and then some. I got one for my youngest who just started pre-k. Also, all of the prints are vibrant and fun, and the sizes are perfect for each of them 🤩
