Cosworth expands aftermarket product line

Famed U.K. engine company Cosworth has announced an expansion of its product line of upgrade kits and performance parts for sport compact cars. Originally launched for the Duratec-powered Ford Focus, the product line now includes high performance engine components for MINI Cooper, Subaru, Mitsubishi and Nissan. Products include CNC-ported Big Valve cylinder heads and Cosworth Forged Pistons.
You get what you pay for - Cosworth's Subaru EJ25 Performance Cylinder Heads (pictured) sell for $3,795 a pair.
