Mantis High-Output Ignition Coil — Subaru / Toyota FA & FB Boxer Performance Ignition Coil (86 / GR86 / BRZ / WRX)

Built for the Subaru and Toyota FA and FB Boxer engine family found in the 86, GR86, BRZ and WRX, this Mantis high-output ignition coil is the direct upgrade for a platform loved for its high-revving character — and one where consistent spark quality right through to redline makes a real difference to how the car feels.

Why Choose the Mantis MTP-1015?

• 12% More Spark Energy — a neodymium magnetic core saturates faster than standard ferrite, storing more energy for a stronger spark.
• Consistent Output, Idle to Redline — engineered to hold spark energy constant at high RPM, where standard boxer coils can lose charge time.
• Built for Boost — equally suited to the turbocharged WRX, keeping ignition strong under sustained cylinder pressure.
• Direct OE Plug & Play — fits straight in across 86, GR86, BRZ and WRX Boxer applications. No wiring or coding required.
• 2-Year Warranty, UK Stock — UK-engineered and tested, same-day dispatch on orders before 3pm.

Cleaner cold starts, a smoother idle and confident ignition all the way to redline — the Mantis MTP-1015 is built for how you actually drive your Boxer-engined Subaru or Toyota.
