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 product, thoughtful design, great customer service
Color: Black, Size: 40 oz
I don't write a lot of reviews, but I felt like this product deserved one. This is an excellent cold brew maker. It is very easy to use and has a great 1,200 mL capacity. The plastic construction is more versatile (less fragile) than other brewers made from glass. The filtration system eliminates the sludge that other brew systems leave. The packaging is very thoughtful - a scoop and sponge are included. The scoop is easily overlooked, but it is the perfect size to clean the used grounds out of the filter. The sponge is an unexpectedly useful form factor to help with cleaning. Hopefully the sponges can be ordered separately, since sponges don't last forever.
Some minor downsides:
Cleaning is moderately easy, but the only component that is recommended for the dishwasher is the pitcher (which is also easiest to clean by hand). All of the other elements are recommended for hand washing, which doesn't take long.
The way the filter is configured, the pitcher will work most effectively if stored (at least for part of the brew cycle) on its side. However, there is a vent in the lid that is prone to leaking when the pitcher is stored on its side. Brewing upright can lead to the top grounds not getting exposed to water.
Unfortunately, one of the pieces broke during routine use after a couple of months: the pitcher lid is attached with a couple of hinges that snap the lid into place on the pitcher. One of the hinge attachments broke. I contacted customer service and a replacement pitcher arrived four days later. I'd recommend being careful with these hinge attachments as they seem prone to break. At the same time, the customer service is very responsive and suggests that they take support of their products seriously.
