Help keep your intake air temperatures down with the Mishimoto Performance Heat Exchanger explicitly designed for the 2019+ BMW M340i (G20)/Z4 (G29) 3.0L. Air-to-water intercooling is the future for forced induction vehicles, so it's no surprise when the BMW and Toyota tag-team integrated their system directly into the intake manifold for these new aged sports cars. This might maximize the cooling efficiency of the B58, but there are still some shortcomings, especially when it comes to the G20/G29's heat exchanger. Luckily, we here at Mishimoto have the solution.
We started from the ground up with our design, starting by ditching all plastic bits, replacing the end tanks, core, and inlet/outlet ports with a durable aluminum TIG-welded for maximum durability. We also opted to utilize strutted tubes within our heat exchanger core to add even more strength, ensuring an added resistance against bowing and flexing under hard cornering.
There's more to our design than strength as well. In addition to our durability features, we also expanded our heat exchanger's size, adding 31% in core volume and 48% to the external fin surface area. Combined with our dual-pass flow configuration and louvered fin design, we were able to record a 5-7°F drop in intake air temperatures, along with a more consistent global intercooler coolant temperature.
The Mishimoto Performance Heat Exchanger for the 2019+ BMW M340i (G20)/Z4 (G29) 3.0L is available in a natural finish and includes the Mishimoto Lifetime Warranty for a worry-free installation.
*Some modification is required. Factory transmission cooler tabs need to be removed for proper fitment. Mishimoto heat exchanger provides new transmission cooler mounting tabs.
