Product Details

Koyo is well-known for making solid cooling components, and this radiator is a great example of that. If you're looking to keep your 2008-2011 Lexus IS F's 5.0L engine running cool, especially under demanding conditions, this radiator is built to handle the heat. It's designed to be a direct replacement for your factory unit, making the swap straightforward.

This radiator uses a dual-core design, meaning it has two rows of tubes running through it. This setup offers more surface area for the coolant to flow through and dissipate heat compared to a single-core radiator. The tanks are constructed from durable aluminum, which is lighter than the stock plastic and offers better heat transfer. The core itself is also aluminum, known for its efficient heat dissipation. This combination helps ensure your engine stays within its optimal temperature range, preventing overheating during spirited driving or track use.

When you're installing this, you'll find it fits right into the factory mounting locations. You'll want to make sure you have fresh coolant on hand to refill the system after the swap. This radiator is a solid option for any IS F owner who wants a reliable cooling upgrade.
