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.

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The Roo Racing Coil-On-Plug (COP) Conversion Loom allows you to delete the outdated factory coil pack and external ignitor, converting your machine to a modern individual coil-on-plug setup.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.

Not made from the most comfortable fabric
Color: White, Light Gray, Black, Size: Large
It is not the most comfortable fabric which makes it not suitable for summer clothing. Also, the fitting of the neck doesn’t look good since material is not wrinkle free

Excellent Mock Neck T-Shirts
Color: Wine Red, Navy Blue, Black, Size: Medium
 As a man who appreciates comfort and style, I can confidently say these August Alley mock neck t-shirts are a solid choice. I'm always looking for versatile basics, and these fit the bill perfectly. The cotton material feels great against the skin, and they've held their shape well after a few washes. I appreciate the slim fit; it looks modern without being too tight. Whether I'm wearing them casually or layering them under a jacket, they always look sharp. For the price, getting a 3-pack of these quality shirts is a fantastic deal. Highly recommend them for any guy looking to upgrade his basic tee collection.

One of the Best Watch for the Price
Color: Black/Gray
Second time purchase of this model. The strap on the first one broke after 5 years and the original battery is still in it. Just found out that you can purchase replacement swap from Timex direct or through retail stores like Walmart and Target. The replacement straps are about $12. I mentioned this because as other reviewer of this watch or similar mode, the major con is the strap seems to break after several years. The other con of this watch is that the “start/split” button which is used to change time zone is on the face of the watch of the watch. It is slightly raised, so it is easy to accidently change time zone when sleeping. This watch looks good, very rugged, have taken it out many times snorkeling and shows no indication of water leakage. The oversize display is easy to read. The indigo light makes the watch easy to read at night and the night feature when turn on, will auto-light the display when any button is pressed. I travel a lot and really like the three time zones. Another hidden feature not mentioned by others is the custom menu feature. You can selectively pick the features you want to use and reduce the number of features you have to cycle through. This is an excellent everyday watch, very rugged, and accurate. On the previous one, I didn’t have to reset the time at all during the 5 years of use. The number for Timex Support is: If you can't find your strap, you can also order one by calling our Customer Service Department at 1-888-727-2931. I also had the traditional size display before discovering the oversize mode. The oversize is a lot easier to read.

Works great, rugged, and worth the money!
Color: Black/Gray
Just purchased my second of this watch as a replacement. The first lasted about four years of abuse before the straps started to crumble. No battery or other issues. It had survived Afghanistan, numerous field exercises, mud, sweat, rain, wind, etc. and was well worth the $35 I spent on it. It is easy to adjust the time and has a handy 2nd time feature if you're between two time zones frequently or jut want to know the time back home. Everything else is what one would expect from the Ironman series. Lightweight, good backlight (indiglo), not obnoxiously large, rugged, good chrono/timers/alarms.
