A HKS fuel cut defender will allow boost pressure to be increased above the factory level and will prevent momentary shutdown of the fuel injection system when boost increases. This allows for an accurate and simplistic increase in the factory fuel cut out level without the need for cutting wires or affecting off boost conditions and can be locked out to prevent tampering. The unit itself is subtle and compact, constructed from a durable and lightweight billet alloy, ideal to be shown off or tucked away - whatever your requirements.The HKS fuel cut defender comes supplied complete with fitting kit.
