Frequently Asked Questions

Do I need to change my oil filter location or plumbing?

No — the included high-flow adapter replaces your stock oil filter head and routes oil through the cooler. All lines and fittings are in the box.

Will this cool my oil enough during highway riding?

The 6-row aluminum core and HyperFlow design are engineered to maintain safe oil temps during sustained highway speeds on Twin-Cam engines.

Does it cool oil all the time, or only when needed?

The automatic thermal bypass valve only engages cooling when oil gets hot, so you're not unnecessarily cooling oil during cold starts or light riding.

What's the installation difficulty?

JAGG includes all necessary hardware and lines. Most riders complete installation in 1–2 hours with basic hand tools.
