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

Easy on and off
I’m a big fan of Sauconys so I wanted to introduce my daughter to my love of sneakers. These are good shoes and they’ve held up well. They show a lot of dirt but they’re worn by a toddler so I guess that’s expected. They’re lightweight so my daughter can easily walk in them. My only complaint is the length of the Velcro fastener. We use thin socks and the fastener barely goes halfway across the shoe. It just looks odd to me. Otherwise, it’s a great shoe. I’ll definitely buy more.

Cute shoes for new walkers
Great shoes for new walkers, with a sturdy heel cup and flexible sole, and super easy to get on/take off. The fit is a bit on the narrow side, so recommend checking the size chart. Great colors too! We've bought multiple pairs in different sizes and have always been happy.

Great shoe: 5th pair purchased!
I love these shoes! They fit true to size and never wear out. Both of my girls have worn these exclusively from 9 months through kindergarten. My oldest just learned to tie laces and that’s the only reason I’m moving her on to different shoes. These are stylish and they grow out of them before the tread even begins to show wear. Additionally, unlike cheap sneakers from Walmart or Target the Velcro holds strong despite a year of use by two different children.

Great purchase!
My child is 14 months and has been on the move for a long time, these shoes are so great, he moves great in them and never has a problem wearing them!
They are slightly narrow so the strap doesn’t go all the way, but has never come undone!

Worth every penny
My son’s favorite shoes! High quality, very durable, look nice even when they aren’t freshly cleaned. Easy to take on and off. Definitely worth the money! This color tends to go with everything. Such great support.
