Coil On Plug Conversion Full Kit – WRX & STI GC8 (1994 - 2000) & Forester GT EJ205 (1998–2002) | Roo Racing x NGK

Modern ignition for old-school EJ reliability.

Bring your early-model EJ ignition system into the modern era with the Roo Racing Coil-On-Plug Conversion Kit - a proven upgrade used and recommended by Subaru tuning specialists across Australia.

This full kit replaces the ageing factory single coil pack setup with individual NGK U5057 ignition coils, powered by our locally built Roo Racing plug-and-play conversion loom.
The result? Stronger spark, smoother running, better response, and improved stability under boost.

No cutting. No splicing. No ECU mods.
Just a clean, reliable, Australian-made solution.
