If you're looking to really wake up your Focus ST, you’ve got to check out the Ford Racing ProCal Calibration Tool paired with a Cold Spark Plug Set and a Cold Air Intake. I’ve had the chance to put this setup through its paces, and let me tell you, the difference is night and day. Just by swapping in those colder spark plugs, tuning it up, and letting that cold air intake do its thing, I saw a huge jump in torque—like 90 peak torque at 2800 RPM when running on 93 octane. And it doesn’t stop there; you feel that torque surge all the way up to 4200 RPM. It’s like the car just wants to keep pulling and pulling.
Plus, the horsepower gains are noticeable throughout the entire RPM range, which makes every drive a lot more thrilling. And let's not forget about the sound—Ford tweaked the sound symposer software and calibration, so you get a more authentic engine growl that just feels right. It’s a little more aggressive without being over the top, perfect for those spirited drives.
The setup includes the Spark Plug Calibration Kit, which comes with the Ford Performance Calibration using ProCal3, along with the Spark Plug Kit (PN M-1420-FSTA) and the Cold Air Intake (PN M-9603-FST). It’s all made to fit together seamlessly, giving you that boost you’re after.
Universal Fitment: These components are designed to work with your vehicle as they have a universal fit. Still, it's a good idea to do your homework to ensure compatibility with your specific setup. A little research goes a long way in confirming that this will work for your ride.
