DEI 010107 Exhaust Wrap 1" x 50ft Black ymm_59 The cooler is a bolt ymm_15 The cooler is a bolt on design for the factory radiator or the CSF High Performance Radiators (E46 M3 CSF #7058 E39 M5 #7064) and uses the factory oil cooler lines This is especially true when “long” pushrods and valves are employed – you should raise the “installed height” of the rocker arm to compensate for the longer than stock components Less under hood radiant heat results in a cooler air charge for improved performance and keeping exhaust gases hotter within the exhaust system helps in decreasing exhaust density & increases exhaust flow An important first step in reducing unwanted and power robbing under hood heat is wrapping headers and down pipes
