Add excitement to your 930 with our wastegate boost springs. The acceleration is phenomenal. And you have peace of mind knowing you cant inadvertently turn a dial too far and fry your engine. Choose two levels of boost: from 1.0 bar (20% over stock) or 1.2 bar (33% over stock). 1.0 bar is best for most street driven Turbos, while the 1.2 bar spring is recommended for cars with larger (aftermarket) intercoolers or fuel enrichment devices. Fits all 930s 1976-94. Note: A boost spring will not cure a faulty wastegate; make sure yours is functioning properly before installing the spring. Learn More
