Walkinshaw Performance W407


Building on the hugely successful W375 package, the Walkinshaw Performance W407 adds more performance and excitement to the W Series range by offering our best naturally aspirated package to date. Utilising a Walkinshaw Performance spec camshaft and associated componentry provides more top end power and torque whilst maintaining road handling manners for your daily drive.w407

In addition to the Walkinshaw Performance camshaft, the package makes use of a full stainless steel, stepped exhaust system, ceramic coated 4 into 1 long tube headers and high flow catalytic converters and an over the radiator cold air intake to gather greater volumes of airflow into the engine. This results in greater efficiencies in power and economy and is finished with all infill panels and shrouds keeping the with original equipment look of the vehicle.

An ECU recalibration developed on a dyno optimises the specific combination of carefully chosen componentry, resulting in a thrilling driving experience that stands out from the crowd. The package is supplied with rear deck lid badging, engine bay identification, certificate of Authenticity and Walkinshaw Performance’s unique driveline warranty for complete peace of mind.

Current W375 Owners will be pleased to know their vehicles can be upgraded to the W407 and should contact their nearest Authorised Walkinshaw Performance Agent to discuss.
