You are viewing a BRAND NEW JUN Racing Intake and Exhaust Valve Guides for many 6 Cylinder cars. These are very hard to find out side of Japan and they will come to you directly from Jun Auto as if you were able to purchase them right here in Japan. This is what Jun has to say about their products. In the case of tuned engine, the heat and mechanical load of high rpm vehicles is much greater than stock engines. The use of stock valve guides in high performance engines may lead to engine damage. The JUN Racing Valve Guide is improved in strength and heat conduction by using raw material, phosphorus-bronze. This therefore avoids the any damage from high rotation of tuned engine. They are designed for the following vehicles (please specify upon purchase)
