GReddy 10-Row Oil Cooler Kit – 2000–2009 Honda S2000 (AP1/AP2) | F20C / F22C | Direct-Fit Application-Specific Kit

The GReddy 10-Row Oil Cooler Kit for the 2000–2009 Honda S2000 (AP1/AP2) is a complete, application-specific oil cooler kit engineered to reduce oil temperatures in the S2000's high-revving F20C and F22C engines under sustained high-performance and track use. The Honda S2000's naturally aspirated F20C and F22C engines are among the highest-revving production car engines ever built — capable of exceeding 9,000 RPM in the F20C — and they generate significant heat under sustained track use. Elevated oil temperatures reduce oil viscosity, accelerate oil degradation, and increase engine wear — making oil temperature management a critical reliability and performance consideration for any track-driven S2000. The GReddy 10-row oil cooler kit provides the additional oil cooling capacity required to maintain safe oil temperatures under sustained track use. GReddy (Trust) is one of the most iconic and respected JDM performance brands in the world — a Japanese manufacturer with decades of motorsport and performance development experience for Honda, Toyota, Nissan, and other Japanese performance platforms.

Key Features:

• 10-row oil cooler core — GReddy's 10-row oil cooler core provides significant additional oil cooling capacity compared to the factory oil cooling system — correct for sustained track use where oil temperatures would otherwise exceed safe operating limits
• Application-specific kit — engineered specifically for the 2000–2009 Honda S2000 AP1/AP2 — correct oil cooler sandwich plate, fittings, and lines for the S2000's oil filter location and engine bay routing
• F20C and F22C compatible — correct for both the AP1 (F20C 2.0L) and AP2 (F22C 2.2L) S2000 variants
• Reduces oil temperatures — lower oil temperatures maintain correct oil viscosity under sustained high-RPM use — protecting engine bearings, valve train, and other oil-lubricated components from the accelerated wear caused by overheated, thinned oil
• Extends oil service life — lower operating temperatures significantly slow oil oxidation and degradation — maintaining oil quality between service intervals
• Complete kit — a complete oil cooler kit including the cooler core, sandwich plate adapter, lines, and fittings — everything required for installation in a single kit
• GReddy quality — manufactured by GReddy (Trust), one of the most iconic and respected JDM performance brands in the world

Why the S2000 Needs an Oil Cooler for Track Use:

The Honda S2000's F20C and F22C engines are high-revving, high-specific-output naturally aspirated engines — the F20C produces approximately 240HP from 2.0L, giving it one of the highest specific outputs of any naturally aspirated production engine. At sustained high RPM on a race circuit, these engines generate significant heat — and the factory oil cooling system is designed for street use, not sustained track use. Under track conditions, S2000 oil temperatures can rise to levels that thin the oil beyond its effective viscosity range — reducing the oil film thickness at bearing surfaces and accelerating wear. An oil cooler is not an optional upgrade for a track-driven S2000 — it is a critical reliability component that protects the engine from the heat generated by sustained high-RPM track use.

10-Row Core — Cooling Capacity:

GReddy's 10-row oil cooler core provides a meaningful increase in oil cooling capacity over the factory system — correct for the S2000's track use requirements without being excessively large for a street-driven car. The 10-row core strikes the correct balance between cooling capacity and warm-up time — providing sufficient cooling for sustained track use while allowing the oil to reach operating temperature in a reasonable time on cold days. For S2000 owners who primarily track their car, the 10-row core is the correct specification.

Specifications:

• Brand: GReddy (Trust)
• Part Number: GRE12058005
• Core Rows: 10
• Type: Complete oil cooler kit
• Application: 2000–2009 Honda S2000 — AP1 (F20C) / AP2 (F22C)
• Weight: 12.6 lbs (shipping weight — complete kit)

Fitment Information:

• 2000–2003 Honda S2000 — AP1 — F20C 2.0L

• Application-specific — correct sandwich plate, fittings, and line routing for the S2000's oil filter location and engine bay
• Note: Verify your specific S2000 model year (AP1 vs. AP2) before ordering — confirm that GRE12058005 is the correct oil cooler kit for your specific S2000 generation. Professional installation recommended. An oil thermostat is recommended for street-driven S2000s to prevent oil from running too cold in winter conditions.

What's Included:

• GReddy 10-row oil cooler core
• Oil cooler sandwich plate adapter (oil filter relocation)
• Oil cooler lines and fittings
• All required hardware
• Refer to GReddy's product documentation for complete kit contents and installation instructions

Installation Notes:

• Professional installation recommended — oil cooler installation requires correct sandwich plate torque, correct line routing to avoid heat sources and moving components, and a thorough leak check before the first start
• Perform a thorough oil leak check after installation before the first start — pressurize the oil system by cranking without starting and inspect all connections for leaks before firing the engine
• Route oil lines away from exhaust components, moving suspension parts, and sharp edges — oil line contact with hot exhaust or moving components will cause line failure
• An oil thermostat is recommended for street-driven S2000s — a thermostat prevents oil from flowing through the cooler until it reaches operating temperature, preventing overcooling in cold weather conditions
• Use fresh, high-quality full-synthetic engine oil after installation — the additional oil volume in the cooler and lines will dilute the existing oil
• Monitor oil temperature after installation — verify that oil temperatures remain within the correct operating range under both street and track conditions
