The HKS Turbo Timer is designed to extend turbocharger life by allowing the engine to idle for a pre-set amount of time after the ignition key has been turned off and removed. This permits the engine oil to circulate through the turbocharger bearing housing, drawing heat out of the bearings and impeller shaft in order to bring the temperature down to a safe level before the engine is shut off. If the turbo is not allowed to 'idle down' the bearings will cook in the hot engine oil which can cause severe damage over a period of time.

This process of cooking the bearings is known as 'coking'. Coking is the No. 1 cause of bearing faliure in turbochargers. HKS engineered the first commercially available turbo timer in the early 80's and continues to deliver the most user friendly and reliable unit on the market.

Realisticly, timers are usually only on for a relatively short period (around 90~180 seconds). In this time, a potential theif will have to break into the car (as you can still lock it), get round the steering lock (as you have the key) and even if they do manage this, the turbo timer automatically switches off if it senses that the handbrake has been let off (leaving the theif stranded).

Confusion arises when central locking is remotely activated, but several of our customers have stated that a good vehicle alarm installer can re-wire the set-up to accomodate the turbo timer.
