After the advent of space-age memory foam, springs sure seem low-tech in the world of performance sleeping. In the realm of performance driving, though, springs are still the best way to regulate the amount of boost that's blowing into your turbo. For the ultimate control over your ride's boost, customize your wastegate with Turbosmart Actuator Springs—the only interchangeable Wastegate Springs designed exclusively for your Turbosmart Actuator.
Whether you're aiming for a modest 3PSI, a hard-charging 14PSI or a custom boost level, Turbosmart Springs make it simple. They designed each Waste Gate Actuator Spring to work alone or in groups, so you can mix and match different springs for the optimal PSI. Simply stack up to three springs together inside your Wastegate, and you'll hit the ideal boost rate for your speed fiend.
You don't need an advanced degree in mechanical engineering to install your new Turbosmart Actuator Springs. Just pop off the locking collar, pull out your old spring and fit in the new. For the best results, make sure to run your Wastegate with a Turbosmart e-Boost Controller. What's more, it comes backed by a 1-year warranty.
