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)

Great for many ways on my leather goods!
Size: 16 Fl Oz (Pack of 1)
This stuff got the smell out of a purse I bought that had a chemical smell online. I mean, I try to wash this person all kinds of stuff and couldn't get the stink out of it. I thought I was gonna have to throw it out. I bought this at the last attempt to fix it and it got rid of the smell! I also used it on all my leather shoes, and I cleaned my leather headboard. All shiny and moist now. I know this is for cars, but I don't have any leather seats in my cars. But everything I used it on is clean and smells better.

The smell is wonderful
Size: 16 Fl Oz (Pack of 1)
This product smells really nice. Like clean fresh leather. My seats look nice. My dog had an accident all over the front of my seat and after cleaning thoroughly, this seemed to really help.

Chemical Guys Leather Quick Detailer for Car Interiors 32oz
Size: 32 Fl Oz (Pack of 1)
Reliable Quick Cleaner for Leather Interiors I’ve been using the Chemical Guys Leather Quick Detailer on my car’s interior for a while now, and it’s become one of those go-to products I like to keep on hand. As the name suggests, this is designed for quick touch-ups rather than deep cleaning, and for that purpose, it really does the job well. The first thing I noticed is how easy it is to use. A couple of sprays on the leather seats or steering wheel, a quick wipe with a microfiber cloth, and the surface instantly looks cleaner. It removes light dust, dirt, and fingerprints in seconds. Unlike some products I’ve tried in the past, it doesn’t leave behind a slick or greasy feel, which is important when you’re dealing with things like a steering wheel or gear shifter that you’re constantly touching. Instead, the finish is clean, soft, and natural-looking, which is exactly what I want. The scent is another plus. It has a pleasant, subtle leather fragrance that makes the car smell fresh without being overwhelming or chemical-like. I don’t like products that leave behind a strong odor, and this one strikes the right balance. Another strength is its versatility. While it’s marketed as a car interior detailer, I’ve found it works well on other small leather items, like a laptop bag or even a chair at home. Obviously, it’s not a replacement for a full leather conditioner, but for light upkeep it’s nice to have a single product that can handle more than just my car. That said, there are a few things that keep this from being a perfect 5-star product. First, it’s definitely not designed for deep cleaning—if your leather is heavily soiled, stained, or dried out, this won’t be enough. You’d need a dedicated cleaner and conditioner for a full restoration. Second, the spray nozzle can be a bit inconsistent, sometimes giving off more of a stream than a fine mist. It’s not a huge issue, but it can waste product or make application less even if you’re not careful. Lastly, while it makes leather look clean and refreshed, it doesn’t provide as much conditioning as some other products, so if you’re looking for something that really nourishes and protects long term, this is more of a maintenance step than a solution. Overall, though, I’m very satisfied. The Chemical Guys Leather Quick Detailer is perfect for keeping leather looking sharp between major cleanings. It’s fast, effective, and leaves behind a clean finish without unwanted residue. It saves me time and keeps my car interior looking well cared for, which is exactly what I want from a quick detailer. I’d rate it 4 stars—an excellent product for regular maintenance and touch-ups, with just a few small shortcomings that prevent it from being the ultimate all-in-one leather care solution.
