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 Kits

Intercooler Kits

A complete intercooler kit replaces or upgrades the entire charge cooling system in a single purchase, providing the intercooler core, piping, couplers, clamps, and hardware needed for a clean install. Upgraded intercooler kits are one of the most effective power-supporting modifications for any turbocharged build targeting higher boost pressure. Popular Upgrades Top-selling intercooler kits include front-mount intercooler kits for popular turbocharged platforms like the Ford Focus ST, Mustang EcoBoost, Subaru WRX, and Mitsubishi Evo, side-mount intercooler upgrades for rotary and compact turbo cars, and direct-fit top-mount intercooler upgrades for factory top-mount locations that maintain OEM fitment and aesthetics. How much power can an intercooler kit add? An intercooler kit does not add power by itself but supports power gains from increased boost pressure, aggressive tuning, or larger turbocharger upgrades by maintaining safe intake air temperatures. An oversaturated factory i...
