Better Tubing

Construction

PERRIN boost tubes are CNC mandrel bent with high quality rolled beads to hold more boost. The smaller boost tube also features a super beefy upper chassis mount.

Silicone

Our upper boost tubes use high quality 4 ply silicone couplers. The hot side plumbing features 2 tubes connected by a "hump" style coupler to allow engine movement without breaking tubes or tearing couplers.

Blow off valve

The PERRIN upper boost tube kit relocates the blow off valve hose for cleaner simpler installation which makes blow off valves easy and quick.

T-Bolt Clamps

PERRIN T-bolt clamps are designed for uniform clamping at all points around the band. The wider band distributes the force over a larger area and the Fine threaded bolts with nylon lock nuts allow for accurate torque and proper clamping. Never re-tighten down the road, plus each PERRIN logoed clamp is made in the USA and has the torque spec engraved on each one.
