turbo timers.

I’ve been considering buying a $100 turbo timer for my eclipse. I’m not entirely sure if I need one or not. I drive 2 miles to work, 2 mile home. Is it necessary to buy one, when is it necessary. Which ones are better? 96 gsx awd

Driving to work doesn't warrant a turbo timer. The only time you would want the car to cool down is after running it hard repeatedly.
