Kiggly 4G63 HLA Pressure Regulator (HLA_UNIV) STM or hammersActively regulates lash adjuster supply pressure to a constant 15psi by restricting flow instead of dumping extra pressure like the JDM regulator. Reduces oil flow into the head, keeping more oil in the pan and can greatly improve oil pressure at the end of a 1 4 mile pass. Air bleed at the highest point helps oil quality and aeration to lash adjusters. Vehicle Fitment: Mitsubishi 4G63 1992 2006 Evolution I IX 1990 1999 Eclipse GST GSX 1990 1998 Talon
