GReddy 14550401 High-Capacity Differential Cover V2 for S2000 AP1/AP2

GReddy 14550401 is a Version 2 large-capacity cast aluminum differential cover designed for the Honda S2000 AP1 and AP2. This precision-engineered cover significantly increases differential oil capacity and improves cooling performance compared to the OEM unit, making it an essential upgrade for track-driven and performance-oriented builds.

Key Features:

• Cast aluminum construction with impregnation treatment for strength and long-term durability
• Increased oil capacity of approximately 1.9L — nearly 2.4× the stock 0.8L capacity, while optimized down from the previous V1's 2.3L for better balance
• Integrated baffle plate prevents oil from shifting under acceleration, maintaining consistent lubrication to the differential
• Heat dissipation fins positioned in the airflow path to actively improve cooling during driving
• Reinforced jack-up point for safe lifting without compromising structural integrity
• Dual 3/8 NPT IN/OUT ports for optional external differential cooler integration (cooler sold separately)
• Muffler-compatible redesign — updated outer shape accommodates a wide variety of exhaust configurations, including dual left/right muffler setups

The GReddy differential cover is precision cast from aluminum and impregnation treated for porosity resistance. Oil capacity is rated at approximately 1.9 liters versus the factory 0.8 liters. This Version 2 design addresses the fitment limitations of the original cover with an updated profile that clears a broader range of aftermarket exhaust systems.
