The black powder-coated finish provides a sleek, stealthy appearance while offering excellent corrosion resistance. Designed for both stock and modified setups, the kit reduces pressure drop, improves throttle response, and supports higher boost levels for noticeable performance gains.

Key Features

  • High-Flow Aluminum Piping – Mandrel-bent for smooth airflow and reduced turbulence
  • Black Powder Coat Finish – Sleek appearance with superior corrosion resistance
  • Premium Silicone Couplers – Reinforced for durability under boost and heat
  • Direct Fit – Bolt-on replacement for factory boost tubes on 2002-2007 WRX/STI

Forced Induction

Forced Induction

Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...

Intercooler Components

Intercooler Components

Intercooler components let you build, upgrade, or repair your charge cooling system without replacing the entire intercooler assembly. Quality piping, silicone couplers, mounting brackets, and core upgrades make a meaningful difference in keeping intake temperatures low on high-boost builds and daily-driven turbocharged vehicles alike. Popular Upgrades Frequently ordered intercooler components include upgraded silicone coupler hose kits to replace cracked or blow-off-prone rubber hoses, intercooler core upgrades for higher bar-and-plate or tube-and-fin density, aluminum intercooler piping sets that replace restrictive OEM plastic pipes, and universal mounting brackets for custom intercooler positioning on fabricated builds. What causes intercooler components to fail? The most common intercooler component failure points are silicone or rubber couplers that crack or split under repeated heat cycling, plastic OEM piping that becomes brittle over time, and mounting brackets that fatigue...

Intercooler Pipe Kits

Intercooler Pipe Kits

Intercooler pipe kits replace the factory plastic or thin-walled metal charge pipes that connect the turbocharger outlet to the intercooler and the intercooler to the throttle body. Upgraded aluminum or stainless steel pipe kits eliminate common boost leak points while improving airflow through larger diameter and smoother bends compared to OEM routing. Popular Upgrades Best-selling pipe kit upgrades include mandrel-bent aluminum intercooler pipe kits for popular turbocharged platforms including the Ford Mustang EcoBoost, Focus ST, Subaru WRX, Evo X, and Volkswagen GTI, silicone coupler connector kits for pairing with existing pipes, and stainless steel charge pipe upgrades for high-boost diesel truck applications. Why do factory intercooler pipes fail? Factory intercooler pipes on many turbocharged vehicles are made from molded plastic or thin stamped aluminum that was engineered for stock boost levels. When boost pressure is increased through a tune or turbo upgrade, these pipes a...
