RS MK2 Spark Plugs.
These are original (O.E.M) Ford Focus RS MK2 (305Bhp) spark plugs. Available as a direct replacement for the Focus ST225 whether your car is std or modified.
This is a simply modification ideal for increasing performance.
These RS MK2 plugs can be fitted to a standard Focus ST225 and are especially effective on those fully modified 300Bhp cars due to the higher heat rating, and smaller gap of the plug which ensures the engine can handle high levels of boost.
You will notice increased smoothness through the rev range, no spark blow under full boost, and increased performance all round the torque curve.
