The air deflector serves as an air baffle and provides optimal cooling of the cylinders. Bolts to the back of the alternator.

Mounted on the rear of the alternator or alternator hub, bolting into or adjacent to the fan housing / ventilation shroud.
What it does:
• Guides airflow from the cooling fan over the alternator and engine to maintain proper cooling
• Extends or positions the alternator hub correctly so pulleys are aligned and belt tension is correct
• Helps ensure consistent air circulation in the engine cooling system
Over time, deflectors or hub extensions can become warped, cracked, or corroded, compromising airflow and misaligning pulleys. A damaged deflector may lead to poor alternator cooling, reduced alternator lifespan, or belt misalignment. Replacing restores correct spacing, airflow direction, and ensures reliable alternator performance under all conditions.

WOSP 200 Series 70 amp Alternator
The WOSP 200 Series Alternators are designed as direct replacements for OEM alternators, making them ideal for classic Porsche restorations, standard road use, or motorsport applications where a smaller, lower-output alternator is preferred.
Unlike the modern 300 Series units, the 200 Series uses traditional round-wire stator technology. This makes them faithful to original designs while still benefitting from WOSP’s reputation for high-quality engineering and reliability.
Key Features of the 200 Series
- Round-Wire
Stator Design – based on traditional alternator construction, offering
reliable charging performance.
- Direct
OEM Replacement – plug-and-play compatibility with factory
alternators.
- Lower
Output Race Alternators – compact, lightweight designs available for
motorsport or specialist builds.
- Durable Construction – built to WOSP’s exacting standards to withstand heat, vibration, and long-term use.
- Easy Fitment – engineered for straightforward installation without modification.
Why Choose a 200 Series Alternator?
