Tomei Valve Seat Rings for 4G63 Evo/ DSM (TA310A-MT01A) Engine Mount 47022R Front (Left) Drilled/Slotted (Cryo-Treated)Tomei valve seat rings for the Evo and DSM are designed to effectively dissipate heat in the 4G63 engine, preventing cracking. Achieving high engine output under high rotation and load is difficult if cylinder cooling is inadequate, as this leads to high cylinder head temperatures and a low knock limit. Racing engines utilize high conductivity metals, such as copper, for valve seats to manage heat. Beryllium copper alloy (BeCu) is ideal due to its
