Each unit is individually pressure tested and features cadmium-plated tubes inside and out to help prevent premature failure and extend product life.<\/p>\n<p>Unlike many aftermarket alternatives, OSC maintains OE integrity by utilizing stainless steel plate or copper and brass concentric coolers where originally equipped, never substituting with aluminum. A precision die-cut gasket ensures a secure, leak-free seal, while all necessary hardware, fittings, clamps, and bushings are included for a complete installation.<\/p>\n<p><span style=\"color: #ff0000;\"><strong>Beyond OE.
