Mantis Performance Coils R56

Sold individually.

Built for the S54 - 343PS of 8,000rpm straight-six.

The E46 M3's S54 is one of the great naturally-aspirated engines, and it asks more of its ignition than almost anything else of its era: individual throttle bodies, 8,000rpm, and six coils firing flat out. Tired coils show up as the classic S54 stumble at high rpm and rough running on cold start.

The MTP-1007 is a direct plug & play replacement delivering 12% more spark energy on all six cylinders, with the thermal headroom for standard, tracked and CSL cars alike.

Signs your BMW needs new coils

• Misfire codes P0301–P0306 on INPA or a generic scanner
• Rough idle when cold, smoothing as it warms
• Stumble or flat spots at high rpm
• Power dropping when the bay is heat-soaked in traffic
• Intermittent check-engine light that clears on restart

Engine: 3.2 S54B32 • M3, M3 CSL & Z4 M (E46/E85/E86) 2000–2008 • 6 coils per car • 2-year warranty • Every unit tested
