BLOX Racing Intercooler Blow Off Valve Gasket for Subaru EJ20/EJ25

Blow off valve accessories let you customize and upgrade your BOV system for better response, louder sound, or improved sealing. From recirculating adapters to replacement springs and diaphragms, these parts keep your blow off valve performing at its best. Popular ProductsTop BOV accessories include replacement piston kits, diaphragm rebuild kits, flange adapters, and sound pipes. Brands like Turbosmart, Tial, and HKS offer direct-replacement accessories compatible with their BOV lines. What blow off valve accessories do I need?Common BOV accessories include replacement O-rings and diaphragms for worn seals, flange adapters for different pipe diameters, and spring kits for adjusting cracking pressure to match your boost level. Can I make my blow off valve louder?Yes, venting your BOV to atmosphere instead of recirculating produces a louder sound. Atmospheric vent kits and sound pipes are available for most bolt-on BOV units to maximize the flutter or horn sound. Explore related cate...

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...
