Better Tubing:
PERRIN boost tubes replace the OEM expandable rubber hoses with hard aluminum pipes and non expanding silicone couplers. Our hot side tubing features a 2.5" outside diameter versus the stock 2.325" 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-Blot 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.
