About the Mantis MTP-1009 Focus ST225 & RS Performance Ignition Coils.
Built for the five-cylinder Fords that still sound like nothing else — the Focus ST225, RS Mk2 and RS500.
The warbling 2.5 turbo five made the Mk2 fast Fords instant legends, and the tuning scene never let go — ST225s run 300+ with bolt-ons, RS Mk2s head for 400+, and the engines take it. The coils are now 15–20 years old, and tired originals are one of the most common causes of boost misfires on these cars. The MTP-1009 is a direct plug & play replacement delivering 12% more spark energy on all five cylinders.
Signs your ST / RS needs new coils
> Misfire codes P0301–P0305 on Forscan or a generic scanner
> Rough idle when cold, uneven five-cylinder warble
> Flat spots or breakup on boost — the classic aged-coil symptom on tuned five-pots
> Hesitation after heat-soak in traffic
> Intermittent check-engine light that clears on restart
