Genuine Subaru Main 80 Amp Slow Blow Fuse

Protect Your Harness. Secure Your Power.

Electrical issues in a classic Subaru aren't just an annoyance—they’re a risk to your entire build. Whether you’re mid-engine swap, repairing old crash damage, or chasing down a mystery "no-start" condition, the main 80-amp fuse is the final line of defense for your wiring harness.

At Roo Racing, we’ve seen enough melted aftermarket fuses to know that when it comes to high-load circuit protection, "near enough" isn't good enough. This Genuine Subaru 80A Slow-Blow Fuse is the factory-correct component designed to handle the specific surge characteristics of the EJ-series electrical system.

The Roo Racing Difference:

• ✅ 100% Genuine Subaru Japan: The exact internal resistance and thermal profile your fuse box was engineered for.

• ✅ Slow-Blow Engineering: Designed to handle high-amperage spikes without nuisance tripping, while providing instant protection during a genuine short circuit.

• ✅ Restoration Essential: The only way to bring a 90s or early 2000s engine bay back to true "Factory-Fresh" technical spec.

• ✅ Specialist Verified: We’ve confirmed this as the correct main fuse for the legendary GC8 and SF platforms.

Why Fit Genuine?

Cheap generic fuses often use inferior alloys that can lead to "voltage drop" or, worse, failing to blow when they should. For a $50 part that protects thousands of dollars in sensors and wiring, the Genuine Subaru piece is the only logical choice for the "Underdog" who values reliability.

Confirmed Fitment:

This 80-amp main fuse is the definitive replacement for:

• Subaru Impreza WRX & STi: GC, GF, GD, GG (1997–2005)

• Subaru Forester GT & XT: SF (1997–2002)
