Mishimoto X-Line Performance Aluminium Radiator – Honda S2000 2000–2009 – MMRAD-S2K-00X
Mishimoto X-Line Performance Aluminium Radiator for Honda S2000
Keep your Honda S2000’s high-revving engine operating at optimum temperature with the Mishimoto X-Line Performance Aluminium Radiator – MMRAD-S2K-00X.
The Honda S2000 is renowned for its high-revving naturally aspirated engine, and controlling coolant temperature becomes increasingly important when the vehicle is driven hard, modified or regularly used on track.
The Mishimoto X-Line radiator has been engineered as a high-performance replacement for the factory radiator, providing increased cooling capacity while retaining a direct-fit installation.
High-Capacity 3-Row Core
At the centre of the X-Line radiator is a substantial 3-row aluminium core measuring approximately 2.05 inches thick.
The increased core density provides a larger cooling area compared with a conventional replacement radiator, helping transfer heat away from the engine coolant more efficiently.
Mishimoto also uses tubes that are approximately 16% thinner than the standard-style design, increasing the available surface contact area and improving cooling efficiency.
This makes the X-Line particularly suitable for:
- Track-day Honda S2000s
- Fast-road vehicles
- Modified and tuned S2000s
- High-temperature driving
- Competition vehicles
- Cars experiencing increased cooling demands
Full Aluminium Construction
The radiator uses aluminium construction with brazed core technology and aluminium end tanks.
Unlike many original radiators that combine an aluminium core with plastic end tanks, the Mishimoto performance design provides a durable solution suitable for demanding performance applications.
Direct-Fit S2000 Installation
The MMRAD-S2K-00X has been designed around the Honda S2000 cooling system for straightforward installation.
It uses vehicle-specific mounting locations and is designed to install without the cutting or permanent modification normally associated with universal performance radiators.
An AP2 adapter is also included within the installation hardware.
Integrated 1/8-inch NPT Sensor Port
Performance and track vehicles often require additional coolant monitoring.
For this reason, Mishimoto incorporates a 1/8-inch NPT port, allowing compatible aftermarket temperature sensors to be installed directly into the radiator.
When the port isn’t required, the supplied plug can be installed.
Magnetic Drain Plug
A Mishimoto magnetic drain plug is supplied with the radiator.
The magnetic element can help capture metallic particles circulating through the cooling system, providing an additional level of protection and making inspection easier during coolant servicing.
Ideal for Road and Track S2000 Builds
The S2000’s F20C engine is designed to operate at exceptionally high engine speeds. Modified engines and sustained track use can place considerably greater demands on the cooling system.
A higher-capacity radiator can therefore be an important supporting modification alongside upgrades such as:
- Performance silicone radiator hoses
- Low-temperature thermostats
- Performance cooling fans
- Fan shrouds
- Engine oil coolers
- Forced-induction conversions
- Track preparation packages
Whether you’re restoring an S2000 with a tired original radiator or building a dedicated track car, the Mishimoto X-Line offers a substantial cooling-system upgrade.

Why Upgrade Your Honda S2000 Radiator?
An ageing or inadequate radiator can struggle to control coolant temperatures during demanding driving. Higher coolant temperatures can result in reduced performance and place unnecessary thermal stress on the engine.
The Mishimoto X-Line radiator increases available cooling capacity, making it especially valuable for S2000s used for:
Fast Road Driving
Improved thermal capacity helps control temperatures during spirited driving.
Track Days
Extended high-RPM operation creates far greater heat than normal road driving.
Modified Engines
Performance modifications can increase the amount of heat the cooling system must dissipate.
Turbocharged or Supercharged S2000s
Forced-induction builds place considerably greater thermal demands on the engine.
Restoration Projects
An excellent performance replacement for an ageing, leaking or damaged original radiator.
