Dinan High Performance Heat Exchanger - BMW/Toyota / A9X / G2X / G42 / 230i / M240i / 330i / M340i / 430i / M440i / Z4 and moreThe 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.
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.
The Dinan B4x/B58 heat exchanger for the BMW G2x/G4x and Toyota A9x Supra assists in improving overall charge cooling using a more robust core (45mm thick Dinan core vs. 26.75mm thick OEM core) that wields 68% more heat transfer surface area for improved cooling capacity. The significant increase in core thickness and full-size end tanks contribute to the overall thermal mass (ability to absorb, store, and release heat) improvement beyond the OEM setup. With up to a nearly 12º reduction in charge air temps recorded over stock the Dinan heat exchanger is ready, and able, to assist in extending your vehicles ability to deliver maximum performance time and time again for your driving enjoyment!
Features:
- Average of 8.7º C reduction in charge air temps with a maximum reduction of nearly 12º 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

Great sport block for sensitive skin
Size: 3.4 Fl Oz (Pack of 1), Style: SPF 50
I use this whole playing tennis or pickleball, it might be a little much for everyday. Does not irritate my sensitive skin. Rich enough for dry skin. Very slightly white cast that quickly fades. Does not run or bother my eyes for sports. Basically perfect in all categories.

Amazing smell great sunscreen
This is easy to apply, but great coverage. I am fair-skinned and always want something for my face to make sure I don't get sunburned. I had a great day at the beach with the family, and will definitely use this again.

Tiny but Mighty
This Hawaiian Tropic Weightless Hydration Sunscreen Stick SPF 60 may be small, but it packs a punch!
Yes, it’s definitely on the tiny side — smaller than you might expect — but it’s become my absolute go-to for quick, reliable coverage. It’s perfect to toss in a purse, beach bag, or even a pocket for reapplication throughout the day.
The formula feels smooth and lightweight, not greasy or heavy. It glides on easily and doesn’t leave that thick, sticky sunscreen feeling. I especially love it for my face, around my nose, and on my shoulders when I need a quick touch-up. The SPF 60 gives great peace of mind, especially during long days in the sun.
Even though it’s small, it’s super convenient and effective. Perfect for on-the-go protection!
