Product Description

Set of Four Performance Racing Cold Spark Plugs for 2013, 2014, 2015 and 2016 Focus STs.

When upgrading your 2013-2016 Focus ST with more modifications it may become necessary to upgrade the spark plugs as well. As the cylinder combustion pressures increase, a colder spark plug may be required. This means adding more boost will require colder spark plugs.

The spark plugs in this set are two heat ranges colder than the stock 2.0L EcoBoost engine spark plugs. They are the same spark plugs that are included with the Ford Performance Calibration Kit (M-9603A-FST).

Sold as a set of four spark plugs. They come pre-gapped to 0.028-inch (0.71mm).

A colder spark plug does not mean the spark plug uses less voltage or produces less electrical energy. The heat range of a spark plug is the range in which the spark plug works well thermally. The main difference that affects the heat range is the length of the insulator nose. A hotter spark plug has a longer insulator nose and a colder plug has a shorter insulator nose. A longer insulator nose means the path for heat dissipation from the insulator nose to the cylinder heat is longer and the firing end stays hotter. Also, more surface area is exposed to the ignited gases so the spark plug is easily heated to higher temperatures. A colder spark plug functions in the opposite manner.

Using spark plugs with too hot of a heat range may result in detonation. If too cool of a heat range is used, the spark plugs may foul.

do these plugs come pre-gapped for my 2013 titanium.....>? If not....do you know what the OEM gap is suppose to be for this solution>? thanks

Asked by: RUKA
The gap should be around .26-.28, .40 is way to wide of a gap.

I have a 2014 Focus ST with Cobb Accessport V3, Cobb CAI, MBRP 3" catted downpipe, MBRP 3" catback exhaust and Cobb FMIC. Running 93 oct OTS tune with Accessport. Should I replace stock plugs with these and if so do I have to reflash with Accessport?

Asked by: Jrod77
You would have to retune for a colder spark plugs.

My original spark plugs that were installed with the FRP tuning/calibration kit need to be replaced. If I use these to replace, will I need to recalibrate using the calibration tool?

Asked by: cps211
As long as you are replacing the plugs with the exact same part number spark plugs you will not need to recalibrate.

What is the recommended gap setting and torque for these plugs?

Asked by: Gregg13FST
They come pre-gapped to 0.028-inch (0.71mm) which is recommended. Torque setting will be the same as your factory spark plugs, please refer to your owners manual.

Are these fine to put into a stock 2014 ST with only a BOV and a COBB intake ? I am not going to be running a bigger turbo for awhile and heard that putting in colder plugs would work good with stock with out fouling  

Asked by: Nate32
You should be fine.
