Kiggly 4G63 HLA Pressure Regulator (HLA_UNIV) STM (6) M8 Lock Washers (BB-836080-B)

(6) M8 Lock Washers (BB-836080-B)

Mishimoto Silicone Radiator Hoses are made with a dual layer combining high grade silicone and heat-resistant embedded fibers to provide efficient heat reduction and increased pressure tolerance

Journal bearing configuration

• Virtually noise-free

With an electronic boost controller you could run 18psi from 3000-6000 and 16psi at 7000rpm because you can tune the boost map in the ECU which will allow you to run the maximum amount of boost at every given rpm

Kiggly 4G63 HLA Pressure Regulator (HLA_UNIV) STM (6) M8 Lock Washers (BB-836080-B)Actively 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
