For the Lotus Elise S2, the "original" (OEM) air conditioning condenser is a factory-standard unit often identified in Lotus service parts lists for the 2001–2011 model years. While Lotus sources these components from major automotive cooling suppliers like MAHLE, the standard units are widely known in the Lotus community for being prone to rapid corrosion.

 

Original vs. Performance Replacement

Owners typically choose between the standard factory-style unit and an upgraded aluminum version. 

OEM / Standard Replacement: These are typically multi-pass condensers designed for the 1.8L Toyota (1ZZ/2ZZ) or Rover K-Series engines found in S2 models.

Pros: Guaranteed fitment with original mounting points and hose fittings.

Cons: Subject to corrosion, especially if the car is driven in damp or salty conditions.

Pro Alloy Performance Condenser: A very popular "better than original" choice among Lotus owners.

Features: All-aluminum construction that will not split or crack like original units with plastic components.

Action: It is often recommended to replace the condenser at the same time as the radiator since the front clamshell must be removed for access.
