How it works
The bypass valve exhausts boost pressure going to the modulator so the internal diaphragm does not rupture under boosted driving. It prevents boost pressure from damaging the vacuum modulator and prevents transmission damage from incorrect pressure boost. The kit T's into the brake booster vacuum line or directly into the intake manifold.
Notes
The bypass valve exhausts the boost pressure going to the modulator so the internal diaphragm does not get ruptured under engine boosted driving conditions.
