Mantis Porsche 911 (997.2/991) & Boxster/Cayman 981 Performance Ignition Coils

About the Mantis MTP-1025 Porsche 9A1 Performance Ignition Coils.

Six fresh coils for the 9A1 flat-six - 997.2 through 991, Boxster and Cayman 981.

The 9A1 fixed the M96's bore-score reputation but kept the flat-six coil problem: six coils cooking at the back of the engine bay. High-mileage 997.2s and 991.1s - and hard-driven 981s and GT4s - show it as single-cylinder misfires and rough cold running.

The Mantis MTP-1025 is a direct replacement engineered around a neodymium core delivering 12% more spark energy than standard OE coils. Fitted as a set of six it restores factory-crisp response - at a fraction of OE money.
