Coil On Plug Conversion Loom – WRX GC8 (1997 - 1998) | Roo RacingBring your late 90s GC8 ignition system firmly into the modern era. The factory waste spark ignition system and external ignitor module on the 19971998 WRX (EJ20G EJ20K) were great in their day, but after nearly three decades of engine bay heat, they are prone to degradation, spark blow out under boost, and annoying misfires. The Roo Racing Coil On Plug (COP) Conversion Loom allows you to delete the outdated factory coil pack and external ignitor,

Bring your late-90s GC8 ignition system firmly into the modern era. The factory waste-spark ignition system and external ignitor module on the 1997–1998 WRX (EJ20G/EJ20K) were great in their day, but after nearly three decades of engine bay heat, they are prone to degradation, spark blow-out under boost, and annoying misfires.

The Roo Racing Coil-On-Plug (COP) Conversion Loom allows you to delete the outdated factory coil pack and external ignitor, converting your machine to a modern individual coil-on-plug setup. By giving each cylinder its own dedicated coil, you get a significantly stronger, more stable, and highly consistent spark delivery which is essential for track-driven cars or anyone turning up the boost.

Unlike later models, the '97-'98 platform requires a proper mechanical solution to bypass the factory ignitor. This kit features a high-quality wiring harness and dedicated bridging cables designed to neatly integrate into your factory setup, giving you a clean, reliable, and motorsport-grade ignition system that is built to last.

What This Kit Does:

  • Converts to Modern COP: Upgrades the factory waste-spark system to individual coils per cylinder.

  • Deletes the Weak Links: Eliminates the aging OEM coil pack and troublesome external ignitor module.

  • Stabilizes Your Spark: Delivers a stronger, more consistent spark across the rev range to eliminate high-boost misfires.

  • Simplifies the Engine Bay: Cleans up old wiring clutter and makes future ignition servicing a breeze.

Key Features:

  • Premium Quality Components: Built using high-spec, motorsport-grade wiring and specialized automotive connectors.

  • Engineered for Performance: Designed specifically to adapt modern COP coils with built-in igniters to the '97-'98 platform.

  • Locally Assembled: Built by crew who understand the platform and tested for maximum reliability.

Vehicle Fitment:

  • Subaru Impreza WRX GC8 (Chassis years: 1997 – 1998)

  • Engine codes: EJ20G / EJ20K equipped with factory offset coil pack and external ignitor module.

Kit Includes:

  • Roo Racing Coil-On-Plug Main Conversion Loom

  • Ignitor Module Bridging Cables

  • Detailed Step-by-Step Installation Instructions

🛠️ Installation Note: Read Before You Install

Please note that due to the factory wiring layout of the 1997–1998 model years, this kit is not a 100% plug-and-play install. To successfully bypass the factory ignitor module, the included bridging cables must be soldered or crimped directly into the engine’s factory ignition loom. If you aren't comfortable with automotive electrical work or proper crimping/soldering techniques, we highly recommend having this kit fitted by a professional automotive electrician or a specialized workshop.

🦘 Roo Racing Tip

While you're updating the loom, don't leave old components in the mix! For the absolute best results, install this kit alongside a fresh set of modern coil packs and brand-new spark plugs gapped to your engine's spec. A premium wiring harness can't fix tired, worn-out hardware.

This conversion isn’t about chasing abstract horsepower numbers on a dyno sheet. It’s about securing crisp spark, rock-solid ignition reliability, and modern drivability for your classic WRX.

🦘 Roo Racing Promise: We only design and stock what we’d trust in our own builds. Quality Subaru parts, engineered right, and backed by people who live and breathe the platform.

Amazing
Format: Hardcover
"You know a poem's good if it makes people feels things" And this novel-in-verse is beyond good. Each word is perfectly chosen to bring you naturally into Selah's world, and her voice is crystal-clear. This was an emotional read for me, and there were so many points that I felt my eyes welling up, sometimes in sympathy and sometimes with joy at her journey. Her friends, teachers, classmates, and family were fully formed as well. I feel like I know and understand them all so well. I want to go chill in Pop's basement. I want to give Selah's Mom a hug and tell her she's doing great. I'd love to be on a team with Mrs. V, and I absolutely adored Selah's close friend Noelle with her smeagoling and dogged determination to stand by her friend. They are people I would have loved to hang out with them. Loved, loved, loved the dragon metaphors. They made Selah's feelings, wants, and desire so clear and relatable. I have a slight obsession with the dragons of Birk, so of course, I gave a little cheer everytime they were mentioned. The FantasyCon scene was lovely, and I loved how it was a turning point on Selah's journey towards finding herself. I always love when the dear nerdly community pulls through. Anyway, I'll probably be throwing this book at everyone's head for a while. It's beautiful, profound, a little cathartic, and important. But also, it's a really enjoyable read! Like, Selah's just a really cool girl. Everything about it was just right, and I feel better for having read it.

Eye Opening!! A great perspective of what is happening in some neurodivergent brain,
Format: Audiobook
What a fantastic book! It gives insight into how neurodivergent people experience the world. I have always heard the phrase "All behavior is communication." I recently listened to an add-on to that phrase: "Distressed behavior communicates a person's distress." I couldn't help but think about this phrase as I read this story. The fatigue of masking is a significant challenge; pretending to be someone you are not is a constant struggle. As a neurodivergent teacher who teaches neurodivergent kids, this story touched my heart, and I highly recommend it to anyone who will listen.

Great book!
Format: Hardcover
I loved the book. It’s a quick read as the novel is written beautifully through poetry. The main character is easy to love and root for. As a teacher who is always advocating for neurodivergent kids, I am often helping parents see the strengths and needs for their child. I love that a book exists where kids can go “That’s me!” and learn to love who they were created to be and find tools that help make the world easier to cope with. The author even gives suggestions and resources in the back of the book. This novel is timely as we are starting to have a greater understanding of the spectrum of Autism. Grandparents and parents are beginning to understand themselves through the diagnosis of their kids/grandkids or even nieces/nephews. Knowing yourself is a powerful thing as Selah (the main character) teaches us.
