NGK Spark Plugs Iridium IX Set Focus ST 2013-2017/Focus RS 2016-2017 is rated 5.0 out of 5 by 9.
Rated 5 out of 5 by from Excellent plugs!!! Plugs lasted about 21k miles New plug (.0295 gap) & Old plug removed (.042) installed at (.0295)

Rated 5 out of 5 by from Nice plugs!! Bought these for my stage 3 2016 focus ST. They come with .044 gap out of the box. Will have to be re-gapped to .028-.036. Overall a great plug that I would recommend to anyone. Rule of thumb is if you're pushing more boost/power, you should upgrade to a colder plug to avoid pre detonation. Not really a necessity but I sleep better at night knowing I'm running these plugs.

Rated 5 out of 5 by from Noticeable difference Replaced the original plugs with these at roughly 35k miles with an Accessport, CAI, and cat-back, there's a definite improvement in performance and the smoothness of the engine. Everything just seems like it takes less effort. Great product, very satisfied.

Rated 5 out of 5 by from Simply the Best You want performance and spend a lot of $$$$ getting there, don't skimp on just leaving the factory plugs and oil on board. Buy a set of these NGK plugs, dump the factory oil after a short 500 mile break-in, change your oil and filter to full synthetic Mobile 1 and gap the plugs and you are done for this small corner of your upgrades. Just do it and you'll experience nothing but the piece of mind running the best products offered for you ST....

Rated 5 out of 5 by from Great product, great company! I don't really need to say much about the plugs, NGK is one of the most renowned spark plug manufactures in the game right now, what should be mentioned is the shipping from CJPP. It took less than 3 days from the time of order to receive the plugs, with free shipping! I don't think Amazon can even compete with how fast CJPP ships their product! I will definitely continue purchasing from them.

Rated 5 out of 5 by from Great Plugs! I've had these installed for about two weeks and they are great! I can't notice any difference from stock but when I start tuning I'm sure there will be differences. I would recommend these to anyone!

NGK Spark Plugs Iridium IX Set Focus ST 2013-2017/Focus RS 2016-2017 Video Transcript
By Bill Tumas: So far I've covered most of the basic bolt on modifications to our white Focus ST. I've got a Roush Cold Air Kit, Cobb Downpipe Full Master Exhaust and recently installed a Cobb front mount intercooler. We plan on getting this car back on the DYNO, before we do so, we want to do one more modification, remove our factory spark plugs, replace them with these iridium plugs from NGK. The iridium tips are going to give us a nice consistent spark. These plugs are one heat range colder, making them perfect for high boost application like our Focus.

For this installation you need a 3/8" ratchet, 5/8 " spark plug socket or 5/8 " deep socket 6" extension, 1/4" ratchet,8 mm socket, spark plug gapping tool, and anti-seize.

We being the install by removing the engine cover. The spark plugs are underneath each of these 4 coils located here. If you making a power that you probably want to change your plugs, there's a good possibility you're way in after market colder, a kit like we are. As you can see the colder kit does cover the hardware, so you do have to remove this pipe and move it out of the way, to be able to remove that coil.

Start by disconnecting it from the rubber hose. Next remove the two mounting screws, and disconnect the rubber sleeve. That allows it push it back far enough to be able to reach the hardware to remove it. I'm going to pull up on this wiring harness to access the hardware. Disconnect the plug in the front. A little twist and pull it right out. Spark plugs require a 5/8" socket to remove it. If you have a spark plug socket that this one here, it'll make the job easier, but a standard 5/8" deep socket with an extension will work as well. The spark plugs come out of the box with a gap somewhere between 45 and 50 thousandths. The Focus ST, we suggest between 30 and 32 thousandths.

Make sure you put some anti-seize on before you install it. You are going to want to reinstall the coil. We'll install the harness, plug it back in. Then repeat the process with the other 3. Now we're done, we'll reinstall our cold air kit. Reinstall our engine cover, and your installation is finished. As you can see installing a set of spark plugs in your Focus ST is pretty straightforward. The NGK iridiums are perfect for a higher boost application. For a stock application you wouldn't need the heat range cold air plugs that we're using here. The installation should only take you around 20 minutes. You'll be back one the road in no time.
