HLA Pressure Regulator for 4G63 by Kiggly Racing
This is one of Kiggly's most popular products and can be found on countless 4g63 powered street and race cars. The Kiggly Racing LLC original design actively regulates lash adjuster oil supply pressure to a constant 15psi. This reduces oil flow into the head and keeps more in the pan. Air bleed at the highest point int he system helps oil quality and aeration to the lash adjusters. It will also reduce the amount of oil pushed to the catch, allowing it to stay in the bottom end.
