Brand: TURBOSMART
This handy kit makes it easy to change the piston springs in your Turbosmart RacePort BOV. Includes the special spanner wrench for the locking collar and three different springs: Pink (Inner, 0-4 in-Hg), Orange (Inner, 4-8 in-Hg), and Purple (Outer, 6-10 in-Hg). Run the Pink inner together with the Purple outer for 10-14 in-Hg. Adding this kit to the Blue 14 in-Hg spring included with the standard RacePort will cover all vacuum demands from 0 in-Hg (supercharged) all the way up to 22 in-Hg.
