DESCRIPTION

Help your 2019+ BMW M340i (G20)/Z4 (G29) 3.0L stay cool with the Mishimoto Performance Auxiliary Radiator Pack! The M340i is becoming an icon for the tuning community, but high coolant temperatures can still bring your track day or canyon carve to a screeching halt.

Luckily, our auxiliary radiators are designed to keep your B58 running at optimal temperatures. For starters, we entirely replaced the slim stock core and plastic end tanks with a full aluminum, TIG-welded construction, sure to stand up to the abuse from the street, track, or drag strip. The core on our new design has also grown. We expanded the core’s thickness to 1.57”, which bumps the core volume by 30% over the stock unit. The updated tube-and-fin design employed on this radiator also expands the external fin surface area by 180% for maximum heat dissipation properties, primarily when used in conjunction with the Mishimoto Performance Aluminum Radiator. To ensure a long-lasting radiator, we also incorporated strutted tubes throughout the core for improved stability and drastically reduce the risk of breaks or leaks.

The Mishimoto Performance Auxiliary Radiator Pack is available in a polished finish for a sleek look under the hood of your 2019+ BMW M340i (G20)/Z4 (G29). Also included is the Mishimoto Lifetime Warranty for a worry-free installation.
