Hello guys please be aware I’m aware that you should pull back the little grey tab parts on the coil pack pigtails but it’s still hard to push down and still get them to release, I found my method to work better but do both. Just be gentle with them.

[@nikoniko893]

Great video, thanks for showing that the plug is angled. I was unsuccessful on my first try, will give it another try on the weekend.

[@PeakPerformanceReviews]

Thanks Niko no problem, yeah just look for the angle be gentle and you’ll feel it screw in naturally and it’ll be easy. Let me know how it goes, please stick around and subscribe we need more good people like you on here 🙌🙌 thanks for watching

@@PeakPerformanceReviews I discovered that the Craftsmen 5/8" spark plug socket was too thick to fit into the small opening. Luckily I had a 16mm deep socket just thin enough to fit in there. Got them changed and I'm hoping the gas mileage improves a bit.

[@PeakPerformanceReviews]

@@nikoniko893 great stuff fella thanks for letting me know.

[@Nyziko]

I have stock fiesta st200, just got my NGK plugs, you think I need to gap them? Intended just for normal use

[@PeakPerformanceReviews]

For a stock turbo car with a stock map I would leave the gap, assuming it’s an OEM spark plug?

[@leojunwei8849]

may i know what is the best gap for RT330? and better use 1 Step Cooler or 2 Step?

[@PeakPerformanceReviews]

Leo Jun Wei imo and from what I’ve always here from the best is 0.26-0.29. Stock is actually fine if not stock just 1 step cooler is fine. I can’t see 2 steps hurting but I can’t say it’ll be needed at the boost levels these kits use imo.

[@15groberts]

Great video! At what millage should you change them?

[@PeakPerformanceReviews]

Dksk As thank you so much for the kind words. Personally I change every 3-5k as I do a hell of a lot of track days and hard miles, for a fast road car realistically Iridium plugs can and will be fine for 15-20k+ I’d personally change every year or every 15-20k dependant hard you’ve been on the car. Most people say iridiums have 30k+ life but I wouldn’t leave them that long :-) hope this helps and glad the video help. Stick around and please subscribe as i’d love to hear how you get on :-)

Gapped my factory plugs to 0.26 on my stage 2 fiesta st, its now miss firing at idle, will return them to stock gap when getting full service next week.

[@PeakPerformanceReviews]

Gary Dace I was given the spec by all tuners that race and track there car and have that level of tune. Mine are absolutely fine. Seems odd, check them again and make sure you’ve gapped them correctly, are they new?

[@bristolbullterrier.1434]

Yes they were new, maybe I'll ask ford to gap them to 0.30 on monday when servicing it,but they will probably tell me they need to go back to stock gap.

[@PeakPerformanceReviews]

Gary Dace try .30 for sure :-)

[@jamiesweeting1770]

The grey part of the coil plugs pull back and then you can press them down to release

[@PeakPerformanceReviews]

Jamie Sweeting I know that, to be honest I forgot to say to do that, they still don’t pull out that easily.... well at least mine didn’t, the little method I used works a treat, just gotta be gentle.

[@Anthonythekidwholivesupstairs]

Hey i have a stock fiesta ST and wanna run step 1 colder plugs.....do you suggest .30 for the gap or .26 instead?

[@PeakPerformanceReviews]

Anthony Boyzo personally if your stock standard I would stick to around a 0.30 gap. Anything stage 2 and beyond I’d 100% go with 0.26 from what all tuners have told me. Thanks for watching, please stick around and subscribe as it’ll be great to have you on here.

[@charlieonion9819]

My fiesta st 180 is stage 2, have a exhaust decat dumpvalve and turbo smart dumpvalve, and induction kit airtec with crossover pipe ive had the standard plugs in the car 68000 on it no issues I recently bought ngk plus for it iritium ones will I need to gap them?

[@PeakPerformanceReviews]

Which map/flash do you have? I had Revo and I found you need it so did it. They are pre gapped or gapped for what stock is out of the box but I’ve found that a slightly smaller gap is required or was at least for the Revo stage 2, it would miss fire very easily after not many miles if you didn’t do it. Thanks for watching, please stick around and subscribe as it’ll be great to have you around 🙌

[@charlieonion9819]

@@PeakPerformanceReviews I have a custom remap from a tuner here in Northern Ireland, car running approx 230-240, I’ve never changed my plugs and they are getting changed tomorro just wondering I’m confused what to do as there are so many opinions as I’ve been running it on standard plugs up to now, what do you think? Gap to 0.28?

[@PeakPerformanceReviews]

@@charlieonion9819 if you haven’t had any problems and you haven’t had any break up and you don’t up the power then you can leave the gap as it is out of the box. If really for when you run a map/flash/tune that is running a bit more or quite a lot of boost. A combination of a cooler heat range plug and smaller gap can help. I had problems with mine at Revo stage 2 but if upto now you haven’t had issues you won’t need to bother then. Change plugs none the less but yeah leave gaps as is 🙌

[@mjh00124o]

THAT'S OK you keep plugging away! LOL 👏

[@PeakPerformanceReviews]

MikeJ H lol! Had that coming didn’t I lol.

[@mattiagualini9207]

Ehi Great video! You know what Is the gap For a original st 180 2015?

[@PeakPerformanceReviews]

Thanks Mattia, the stock gaps seem to be around .032-.036. Anywhere around there at stock power is going to be fine .032 the better and aim imo. .026 won’t hurt even at stock power but recommended and worth it at anything higher than stock and especially at stage 2+

[@mattiagualini9207]

Thank you so much!

[@mattiagualini9207]

You can link me the best Spark plugs For st 180 please? Because i think i have One too hot in my engine causing knoking at minimum

[@PeakPerformanceReviews]

Is your car stock? Where in the world are you? You in England?

[@mattiagualini9207]

Yes its stock,im from italy

[@dndkillaztreble5317]

how come the socket size is diffrent on allmost every video some are 10mm some are 14 some are 16

[@PeakPerformanceReviews]

Oh really that’s annoying didn’t know that was the case, have you tried yours yet and seen what size yours is? It’s a Ford thing I think unfortunately

[@simong5131]

Hiya I'm confused I have brought some iradium ITV20tt for riesta st180 what should the gap be on these .? Any help will be appreciated. Simon

[@PeakPerformanceReviews]

Simon G stock gap is about 0.32-38 on a stock plug the gap me and a lot of tuners will recommend is 0.24-28. I wouldn’t know what your gap is on that plug out of its box hence I always personally re gap! Do you have a fillet gauge?

[@simong5131]

@@PeakPerformanceReviews yes i have a feeler gauge the pligs are just over 0.30 out if the box im running a miltek and a airtech induction . So if inset these at around 0.25 these should be fine .? It just looks a big drop down from the 1ml they are set to from out the box

[@PeakPerformanceReviews]

Simon G 0.30 will be fine if they all match you could keep them at that, I’d go down to 0.26 if you are 250+bhp only as those maps run a bit more boost.

[@simong5131]

@@PeakPerformanceReviews thank you for your help 😊

[@PeakPerformanceReviews]

Honestly you are welcome fella no problem at all. I’ve never used the ITV’s personally myself so see how you get on with them. Always just keep an eye on how the car performs with them 👍

[@fluffymat1]

My cars a mp215 if i buy plugs from ford or ngk irridiums would i need to gap them?

[@PeakPerformanceReviews]

fluffymat1 I don’t know for sure about the MP215 but in my opinion I would gap the same as I have as it wouldn’t hurt. The moment any ignition is advanced etc from standard I’d advise the closed up gaps we used.

[@fluffymat1]

Peak Performance Reviews ok Mate nice one,did you go direct to ford for your plugs

[@PeakPerformanceReviews]

fluffymat1 yeah just direct with my local ford. Tbh now from what I’ve seen I wouldn’t use anything other than OEM. Work amazing 👌😎👍

What gap should I have with Ford plugs on a stock ST180? Thanks.

[@PeakPerformanceReviews]

If you get a factory plug the gap it comes with out the box is perfectly fine you won’t have any issues and won’t need to re gap 🙌👌😎 thanks for watching fella! Please stick around and subscribe as it’ll be great to see you on here 😎👌🙌

[@Nyle95]

@@PeakPerformanceReviews Thanks. I do prefer to check though because they're not always right. I think it should be around 0.7mm so if its around that I'll leave it be. Just subbed.

[@PeakPerformanceReviews]

Yeah to be fair they should be spot on or super close but yes I do exactly the same and don’t blame you. 0.032” should be stock spec if I remember rightly which is 0.81mm, 0.71mm is totally fine too I wouldn’t go much smaller than that on a stock car.

[@PeakPerformanceReviews]

Thank you so much for the sub too appreciate it 🙌✅

[@Nyle95]

@@PeakPerformanceReviews Thanks. May I ask where you found this info. as I've struggled to confirm anything so far.

[@Stjka]

0,25-0,26 plug gap... but thats in inch or mm?

[@PeakPerformanceReviews]

0.026" (0.65mm)

[@michaelcarpenter9283]

Does this gap rule apply to all stage 2 cars?

[@PeakPerformanceReviews]

Sorry only just seen this, it is advised at say a level on map that produces say 235-250bhp kind of range, basically at that level the timers are upping the psi of boost pressure quite a bit and this is when a lower gap is needed. So yes anything normally classed at stage 2 or somewhere near the power I was saying could do with the lowered gap I’ve suggested. You can get away with a stock gap but as it gets some heat cycles in after a hard drive out you may get the stock gap increase a little too much and that’s when you’ll have the problems.
