Intake Valve(ea) - 1GR(37.5mm - 1mm Over) Stainless Steel w/Anti Friction Coating
These valves are 1MM larger than stock, great for ported heads that need more flow through the valves. These stainless steel valves are lighter than the stock steel valves, and have a special anti-friction coating to promote better airflow across the valve as well as reduced resistance in the guide, resulting in better valvetrain stability. These valves will work with the stock seats once a performance valve job has been performed. It is highly recommended to unshroud the valve with bowl and chamber port work when using oversized valves. Sold individually
