Perrin Lower Boost Tube Kit Black

PERRIN boost tubes are larger diameter and smoother then stock providing a less restrictive air path from your turbo to the engine. Gain horse power and torque while adding a great looking part under the hood of your EVO.

PERRIN boost tubes replace the OEM expandable rubber hoses with hard aluminum pipes and non expanding silicone couplers. Their hot side tubing features a 2.5" outside diameter versus the stock 2.325" tubing. Their cold side tubing features a 2.75" outside diameter versus the stock 2.325" tubing.

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. Available with textured Black or Red powder coating for a durable finish.

Their 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.

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 logo-ed clamp is made in the USA and has the torque spec engraved on each one.
