Why not utilize the WHOLE core? Let us make you an aluminum shroud that covers the entire core giving you the maximum temperature drop. Our aluminum shrouds have a standard depth of 1/2″ without the fan so they dont rob you of precious engine space. The shrouds are available with or without a fan. Don’t need a fan but need a hole for your supplied fan? No problem. Need the mounting tabs in a special location? No problem. Just supply us with all of the dimensions listed below and we’ll take care of the rest.
