Product Details

The Dinan D780-0003 High Performance Heat Exchanger is an upgraded intercooler replacement designed for 2019-2025 BMW 330i, M340i, 430i, and M440i models equipped with the B58 turbocharged engine. This performance heat exchanger significantly improves cooling efficiency to prevent heat soak and maintain consistent power output during aggressive driving.

Key Features:

  • 68% more cooling surface area and volume compared to the factory heat exchanger
  • 45mm thick Dinan core versus 26.75mm thick stock cooler core for superior heat dissipation
  • Delivers an average 8.7°C reduction in charge air temperatures with maximum reductions of nearly 12°C over 30 successive wide-open-throttle pulls
  • Durable bar-and-plate construction that resists damage from road debris better than stock
  • 100% TIG welded aluminum construction, pressure tested for reliability
  • Direct-fit replacement requiring no modifications for installation
  • Reduces heat soak tendency and helps prevent limp mode during performance driving
  • Improves overall thermal management system efficiency, including engine cooling

This upgraded heat exchanger is an essential modification for BMW owners seeking to maintain consistent performance during track days, spirited driving, or when running increased boost levels. The significantly larger core and improved construction ensure your B58 engine stays cool when it matters most.

I bought the item based on the picture which is different from the actual item, I should have read the disclaimer stating item ma vary from picture

I wanted to order two.

Excellent Speedy service. Very satisfied with the product as well. Told two of my friends to order products from you guys for their vehicles. Which they are.

Fast shipping and great prices

I was not informed that my order was shipped out. When I called and asked about it the rep said it would ship out next week. Later that day I got a notice from FedEx that my order was out for delivery. The product I bought was the correct item I ordered ' brand new in the box' so everything was good in that way.
