BLOX Racing 15-19 Subaru WRX FA20DIT Black Charge Pipe Kit
BLOX Racing black charge pipe kit replaces the factory restrictive hot-side pipe on 2015-2021 Subaru Impreza WRX models with FA20DIT engine. Internal ridges and narrow bends in the stock pipe limit airflow and this direct bolt-on upgrade eliminates those flaws for higher efficiency and performance gains. Mandrel-bent aluminum construction with powder coat finish ensures durability while reducing heat soak.
Key Features
- Mandrel-Bent Aluminum Pipe: Smooth continuous bends replace factory restrictions to deliver unrestricted airflow and boost turbo efficiency
- Powder Coated Black Finish: Protects against corrosion and heat while maintaining sleek appearance under the hood
- CNC Machined Turbo Flange: Precision fit for seamless connection to stock turbo outlet with no leaks or gaps
- Multi-Layer Silicone Couplers: High-density reinforced black couplers handle boost pressures up to 30 PSI for reliable sealing
- Complete Bolt-On Kit: Includes all T-bolt clamps and hardware for easy installation without modifications
Product Notes
- Direct replacement designed for stock turbo setups no cutting or welding required
- Couplers available only in black powder coat options for pipe in black red or blue
- Securely packaged to prevent damage during transit
Installation Notes
- Professional installation recommended.
- Bolt-on process takes 45-60 minutes with basic hand tools.
- All necessary clamps and couplers included compatible with factory intercooler and turbo.

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 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 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...
