The factory B4x/B58 heat exchanger is not built to cater to the rigorous demands often associated with a modified build. The thin core is easily overwhelmed with IAT's rising dramatically once pushed beyond a few successive WOT pulls or even a few minutes at the track. This elevation in temperature gives way to the factory ECU fail safes pulling timing and reducing overall power in order to keep the system from overheating to the point of permanent damage. On an application where enjoyment is directly attributed to pushing the platform to its limits this constraint to cooling presents a challenge for the automotive enthusiast. The Dinan B4x/B58 heat exchanger for the F2x/F3x chassis assists in mitigating these issues with a more robust core (48mm thick Dinan core vs. 27mm thick OEM core) that wields 78% more heat transfer surface area for improved cooling capacity. The significant increase in core thickness requires unique "L" shaped end tanks to be incorporated as well, which also contributes to the overall thermal mass (ability to absorb, store, and release heat) improvement beyond the OEM setup. With up to a 15° IAT delta 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° reduction in IAT's with a maximum reduction of 15° over 15 successive WOT pulls
- Reduces the tendency to heat soak / go in to limp mode
- 48mm thick Dinan cooler vs. 27mm thick stock cooler
- 78% more cooling surface area and volume than stock
- 100% TIG welded and pressure tested
- Installation hardware included (inclusive of xDrive specific transmission oil cooler brackets)

So happy with this product!
It is tasteless so I’m more likely to use it often. I have noticed a difference with more strength and less pain when doing manual labor soi know it’s effective. With all the shoveling and carrying wood in all the time for the stone, I really needed this!
Plus I trust this company for quality products and whenever I need something high quality, I choose them

It needs a scoop otherwise love it.
Got this for my malabsorption that causes brain fatigue and fog. It's working great, too. The lid is a bit odd to open but seals well. My only issue is that it has no scoop. My measuring spoons now have to stay out with the creatine, so I get the proper dosage. If dosage isn't an issue for you, then great. otherwise you need to get another set of measuring spoons.

Great product
I'm not a body builder, at 76 years old I was having muscle aches, and this helps. I take it daily at one teaspoon in my morning coffee.

Highest quality ingredients & secure delivery
Excited to see Pure offer a creatine formula as I already use other products from this highly rated brand. The powder is excellent quality and mixes well. I added it to my protein shake and there was no impact to taste. It digests easily & I experienced zero negative side effects.
The paper canister is a unique, sustainable package. While this may be better than plastic, I had a concern it might get damaged in transit. I was encouraged to see it delivered in a firm cardboard box that was securely protected. The container seals well & is an innovative upgrade from normal bottles.
This is an excellent addition to my routine. Looking forward to seeing the benefits in the coming weeks!
