This part is designed to repair the coolant reservoir cap from a K&N cold air intake kit for a 2011 F-150 SVT Raptor (K&N Part No. 77-2579KTK). Specifically repair a cap that has split in half horizontally from over-tightening once it becomes brittle.

Be sure to print this in a material that can withstand the heat of the engine compartment.

You can buy a replacement reservoir with a cap from K&N but expect to spend $60+ (K&N Part No. AEM-9-0382).
