This billet aluminum coolant cap from JCaps is a precision machined aluminum cover that snugly fits over the factory cap. This cap is designed to fit the late style caps that have the “slotted” design. ECS Tuning has conveniently pre-assembled this coolant cap so it can be installed in your vehicle right out of the box.
JCaps started back when Jay, a mechanical engineer, became the proud owner of a brand new 2004 R32. He sought after high quality, billet machined accessories to dress up the engine bay and interior, but nothing on the market met his high quality standards. The only option was for him to engineer and produce his own precision machined components. The response on the forums was so overwhelming that he began selling them to other enthusiasts, who also shared his attention to quality and detail. All JCaps products are precision machined from 6061 series billet aluminum and include stainless steel hardware, where needed. ECS Tuning is proud to be the exclusive distributor of JCaps by providing the entire catalog in one, convenient online store.
