Subaru WRX Manual Turbo Boost Controller

Throughout the last six years, NXS Motorsports has sold over 18,000 Manual Boost Controllers. Through fine tuning and thorough testing, we have obtained and held a zero-percent failure rate for the last three years. Every one of our Manual Boost Controllers is built and tested right here in the USA. So, add our outstanding feedback, the above guarantees, the promise of excellent service, the inexpensive cost of making your ride faster, and you get one awesome deal. Once you feel the increased power, you will be so glad you tried our MBC. Worth. Every. Penny. Also, 98% of our feedback comes from selling just this one boost controller. Most other sellers sell very few boost controllers and their feedback comes from other items. We invite you to go through our feedback and look at all the wonderful things our customers have said about our MBC. They are very happy with the product and the service, and we know you will be too. Give us a try. You will be glad you did. Electronic Boost Controllers can malfunction, reset, and are very expensive. They can also be a headache to install. Take all the guess work out of the equation and try our MBC. If you're not happy with it, simply return it to us for a full refund minus shipping costs. This ball and spring MBC (manual boost controller) is made from quality parts and is manufactured right here in the USA. The NXS MBC can be used on any turbo car application and can handle up to 30 psi. It is installed in-line with the wastegate setup to fine tune the amount of boost you want to run. Horse power gains of 10hp per 1psi are common on most cars. Did you know that for every 10hp your car gains, you knock off 1/10 of a second on your 1/4 mile ET? It's the best bang-for-the-buck mod you can do.
