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 inch without the fan so they do not 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 you supplied fan? No problem. Need the mounting tabs in a special location? No problem. We’ll contact you after your order is placed to get all the details we need.
