JCaps started 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. 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.
