Mishimoto Ignition Coil

2015–2020 Subaru BRZ / 2017–2020 Toyota 86 Flat-Four Engine

MMIG-BRZ-15

Overview:

The Mishimoto Ignition Coil is a high-quality replacement part designed specifically for the Subaru BRZ (2015–2020) and Toyota 86 (2017–2020) equipped with the FA flat-four engine. This ignition coil addresses one of the fundamental requirements for optimal engine performance: a strong, consistent spark. Over time, factory ignition coils can weaken, leading to misfires, rough idling, and reduced power delivery, especially under high-load conditions. Mishimoto’s coil restores reliable spark energy, improving engine startup, smoothing idle quality, and helping your vehicle maintain peak performance before pursuing further modifications.

Ideal for enthusiasts and daily drivers alike, this coil is engineered to meet or exceed OEM Subaru specifications, ensuring a seamless upgrade or replacement that supports your vehicle’s ignition system health and longevity.

Key Features:

Designed with precision and durability in mind, the Mishimoto ignition coil offers the following benefits:

• Meets or exceeds OEM Subaru performance standards for reliable operation
• Available as a single coil or in a full set of four for complete ignition system refresh
• Improves engine startup response and reduces rough idle conditions
• Restores consistent spark delivery to prevent misfires and spark blow-out under load
• Constructed from robust phenolic resin for excellent heat resistance and durability
• Precision lower boot seals out moisture to prevent spark plug contamination
• Pre-lubricated with dielectric grease to prevent corrosion and ensure optimal electrical connection
• Direct fitment for Subaru BRZ and Toyota 86 flat-four engines, no modifications required
• Backed by Mishimoto’s Lifetime Warranty for peace of mind

Construction & Design:

The Mishimoto ignition coil features a primary frame made from high-grade phenolic resin, a material known for its exceptional resistance to high temperatures and electrical insulation properties. This ensures the coil maintains structural integrity and performance even in the demanding environment of the engine bay. The coil’s lower boot is engineered with precision to create a tight seal around the spark plug, effectively blocking moisture and contaminants from entering the plug well. This design reduces the risk of spark plug fouling and misfires caused by environmental factors.

Additionally, each coil is pre-lubricated with dielectric grease, which enhances the electrical connection between the coil and spark plug while preventing corrosion over time. This attention to detail in materials and assembly guarantees a durable, long-lasting ignition component that supports consistent engine performance.

Installation & Fitment:

Installation of the Mishimoto ignition coil is straightforward and requires no modifications to your Subaru BRZ or Toyota 86. The coil is a direct OEM replacement, designed to fit perfectly with the factory ignition system and spark plugs. For best results, it is recommended to replace the ignition coils in conjunction with new spark plugs to fully restore the ignition system’s efficiency and reliability.

This upgrade is suitable for routine maintenance or as a preparatory step before adding horsepower-enhancing modifications, ensuring your engine’s spark delivery system is operating at peak condition.

What's Included:

• One Mishimoto ignition coil (single unit) or set of four coils (depending on purchase option)
• Pre-applied dielectric grease for corrosion protection
• Installation instructions

Ideal For:

• Owners of Subaru BRZ (2015–2020) and Toyota 86 (2017–2020) seeking reliable ignition system replacement
• Enthusiasts preparing their vehicle for performance upgrades who want to ensure Stage 0 reliability
• Drivers experiencing misfires, rough idle, or poor engine startup due to aging or faulty ignition coils
• Anyone looking for a durable, OEM-quality ignition coil with a lifetime warranty
