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)

Luxury!
I bought for this for someone in a nursing home. She absolutely loves it!! It is so soft! I am surprised how well it has held up because the nursing home uses very harsh detergent when they wash. It is still a delightful blanket!

Buttery Soft, Lightweight, & Warm
You'll be hard pressed to find a more comfortable throw at a better price. I need to get to the couch quick, if I want dibs on this bad boy. My pups love it as well. Soft, light, and toasty warm. Pamper yourself.

So soft and snuggly!
I bought this throw in grey last week and I've only been able to use it once! Since my cats discovered how soft and snuggly it was, they've been laying on it! So, I just ordered another one for me, and this one I will not share!! And you certainly can't beat the price! Highly recommend!!

Good for the price
Love the feel of the blanket and the warmth. If you wash it regularly though, it will start to Matt a bit. Good price on it though

So soft!
I bought this for the chair in my back office where it is always cold. The throw size is perfect for my chair. I also bought a larger size for my couch. I LOVE these. They are warm, comforting, and the long fur is very soothing.
