Product Description
The stock radiator in your Z3 was never designed to handle the aggressive demands of spirited driving, hot summer days, or track abuse. Over time, factory radiators with plastic end tanks crack, leak, and leave you stranded. The Mishimoto Performance Aluminum Radiator is your solution to unreliable cooling and rising engine temps. Featuring a 92% thicker core than stock and a 2-row aluminum design, this radiator significantly boosts cooling efficiency, reduces heat soak, and keeps your BMW's temperature stable—even in high-performance conditions.
More cooling means more power, more reliability, and more confidence behind the wheel. The high-density cooling fins maximize airflow and heat dissipation, while additional contact points allow for superior heat transfer, keeping your engine happy even under extreme conditions. The included magnetic drain plug ensures your coolant stays clean by capturing metal debris, protecting your engine from premature wear.
Mishimoto does not just build performance parts—they engineer solutions. Designed for direct bolt-on fitment, this radiator installs with zero modifications, making it the perfect upgrade for any Z3 enthusiast looking to future-proof their cooling system. And with the Mishimoto Lifetime Warranty, you get peace of mind for the life of your BMW. If you’re serious about performance, reliability, and getting the most out of your BMW Z3, don't settle for an aging factory radiator—upgrade today and keep your roadster running stronger, cooler, and faster!
