Original Pinion is 9 tooth - WOSP is 11 with an offset plate. This is done for increased torque, smoother / faster cranking, and durability.
WOSP high torque, lightweight, gear reduction starter motors are manufactured in the UK. Unlike alternatives in the market place these are built using only 100% OE parts and units, therefore can't be rivalled on quality.
In most cases WOSP starters are designed with an indexable 360 degree mounting plate meaning no obstruction should get in your way when installing.
The main advantages over the original starter is the durability along with a weight and space saving. The improved performance means they also reduce loads on the vehicle's battery and electrical system.
Direct replacements to the original item, plug & play / fit & forget.
All units come with instillation instructions and a 12 month warranty.

300 Series WOSP Alternators
The WOSP 300 Series represents our latest-generation alternator technology,
designed for maximum efficiency and performance. These advanced units use
square wire ‘hairpin’ (segment conductor) stators, delivering exceptional
current density and allowing much higher output compared to traditional
designs.
Each alternator case is precision-machined in-house from billet aluminium,
ensuring strength, durability, and a perfect fit. The result is a range of
plug-and-play alternators built to outperform standard OEM units while
maintaining easy installation.
Key Features
- Advanced hairpin stator technology for superior efficiency
- Precision billet housings manufactured in the UK
- Wide range of direct-fit, plug-and-play applications
• Amp: 175
• Connections: B+ / Lamp
• Construction: Full Billet
• All units are produced to BSI ISO 9002 standards.
• All units have their own serial number for traceability.
