MX5 NA Miata - How to replace your spark plugs and wires

[@Bbeavis]

Nice tips! Plug leads are known to fail over time on the MX-5... :) I should also add, 1mm gap is good for a stock car, but boosted cars tend to work better with around 0.6mm gap.

[@MiataMods]

Thanks for the tip Brendan!

[@4cyl]

Moss miata has them pre gapped for ngk

[@Kj-bi4xy]

I recently bought a miata, it is my first car and i have absolutely no mechanical experience. I wanted to replace spark plugs and wires just as precaution, and your video helped me a ton. Thank you!

[@MiataMods]

Welcome to the club and I'm glad my video was helpful!

[@HARaZAC]

One of the best channels on KZbin for Miata stuff

[@MiataMods]

Thanks for the compliment man! 👌

[@siripx1059]

My god your engine bay is so clean

[@MiataMods]

Thanks man!

[@Saundaz666]

Great vid sir. When I replaced mine, I also found some oil on the spark plug nearest the front. It's very common for the cam cover gasket to fail around that pot so I changed the gasket, which prevented further leaking

[@MiataMods]

Thank you for your reply sir! I will be doing that job in the near future and I will probably paint my valve cover while I’m at it! 👍

[@nickdribler4898]

Upload more videos :) this channel is literally a Miata encyclopedia

[@MiataMods]

Haha thanks.. bought a house which needed a lot of work.. just a few months and then I will have some free time to make more videos!

[@bradnoah6626]

New Miata owner here. Your vids are super helpful!

[@MiataMods]

Welcome to the club!

[@angrydinosaur8plus9]

Thanks for nice, easy to follow video. 5:58 I quieted my lifter tick by going to 0w-40.

[@MiataMods]

Thanks! Got the same type of oil: 0w40

[@diverhose]

I miss you MiataMods!

[@MiataMods]

Miss you too man!

[@Ange47]

Big fan of your videos. Did foamectomy to my driver's seat successfully a month ago. Now this is next :)

[@MiataMods]

It’s very nice to hear that my video was helpful! 👍

[@BecauseMiata]

Very thorough and accurate as usual for your content. Thanks for sharing!

[@MiataMods]

No problem, thanks for watching!

[@Nicole-ju8fd]

That one dislike probably doesn't have a Miata 🤭

[@Oxnard805]

I don’t have a Miata anymore, so I guess I’ll dislike this video 😂

[@toddschoenberger9687]

Two years since you posted this and it's still helping people all over the world, a BIG thank you from Arizona USA! Is there a reason you don't use anti-seize on the threads of the spark plug?

[@MiataMods]

Plugs should be changed at least once a year. Can’t image that they will get really stuck in such a short period of time so I don’t use grease. You could I guess, can’t hurt the engine

[@mtn8426]

I recently bought an mx5, your videos are very helpful! Thanks!

[@MiataMods]

Cool man, I got a lot more you can check out!

[@mtn8426]

Sure! I watched all videos, you are very accurate. Do you will make a video about differential and transmission oil change?

[@MiataMods]

Eventually yes, because I need to do this as well!

[@berndb.5097]

Sehr gut erklärt. Super das Du auch die metrischen Grössen erwähnst. Thumbs up!

[@MiataMods]

Aber natürlich Nachbar! Ich komme aus den Niederlanden, also benutze ich einfach metrischen Grössen :-)

[@WarriorRazor]

Ah, my lifter tick brother! That signature MX-5 sound.

[@MiataMods]

Hey brother 👋 😂

[@josephwakefield5779]

about to do mine with ngk wire set :)

[@MiataMods]

Good luck Joseph 😉

[@schellingrs]

I have a 2000 NB. I love your videos. Keep up the good work! Cheers from Indy USA.

[@MiataMods]

Thanks fellow Miata driver! 👍

[@robinforrest7680]

Thanks for another great video, keep them coming they are clear, easy to follow and very very useful. I changed my plugs when I got my 1995 1.8iS back to France from the UK in May. I put in NGKs which seem pretty good. I'm now wanting to change the HT ignition leads and am thinking of Jackson Racing 8mm. They seem to be around 30-40€. What do you think? I'm on a very tight budget for this car, so any advice on a good value product would be appreciated. Thanks.

[@MiataMods]

Apparently the Miata manual recommends NGK plugs so you installed the right ones! I could not find the right NGK plugs in my country so I bought the Denso plugs. Anyway, about the wires or leads; The Jackson Racing 8mm ones are very good! I've read good things about them and the 8mm outer sheath is an upgrade as compared to the OEM leads so I would say go for it! Thanks for the compliment btw :-)

[@robinforrest7680]

MiataMods I just checked out my copy of the UK MX5 manual. It recommends either NGK or... Denso plugs! So I guess we were both right. The old ones I replaced were Denso... I want to change my engine, transmission and diff oil soon. Any plans for a tutorial for diff and transmission? There are a few on KZbin but they're not very helpful. Im sure you would do a much better job 😉

[@MiataMods]

Okay so Denso plugs are also good! Thanks for sharing that piece of information! Yes I will definitely cover those topics in the near future! Thanks for the compliment ☺️

[@trippm4036]

Great job as usual! glad to see you working in a real world environment. Those plugs looked okay with the exception of the oil on that first one. Was it definitely a bad plug or was it a wire cause the miss?

[@MiataMods]

I’m pretty sure it was that oil soaked spark plug!

[@Chunknannigans]

Usually when i get that lifter tick i change my oil and its good as new, try a thicker viscosity of oil. Drove my car for around 7k miles before it came back, that was after a trip to vegas and a drive to Oregon; I'm from SoCal lol.

[@MiataMods]

I changed the oil 6 months ago and I went for a thicker viscosity but it didn’t really help.. o well, it doesn’t bother me.. sounds like a nice trip tho! I’ve been to California once, loved it! 👍

[@jansmietana4646]

That oil on sparkplug was propably from failed rocker cover gasket

[@MiataMods]

Indeed it was

[@AfortheFOXXX]

Weer een handige en duidelijke video! Nu weet ik ook waar ik op moet letten als ik t zelf ga doen👍🏻

[@MiataMods]

Geen dank man en succes!

[@mattford4736]

Autozone has the NGK coil pack on sale for $180, compared to $100 for cheap oem. Edit: Don't forget to get it shipped to home and use the code for 20% off.

[@MiataMods]

Thanks for sharing that info!

[@burritosausage1657]

I know this is an old video but I have a question, I just replaced my spark plugs and now there’s gas coming from my exhaust. Did I do something wrong?

[@NealChauhan]

Hoping this fixes my P0300 misfire error on my 230km ‘97 NA

[@MiataMods]

Did it fix the problem?

[@wolfgangbakariburst]

When are u gonna do a video on coilovers

[@MiataMods]

Hopefully this winter ❄️

[@RY3ER_]

Informational and fresh - keep at it :) Been looking for one of those gap tools, the coin ones, but so far - only in inches, guess I'll have to go for it then.

[@MiataMods]

Where are you from?

[@RY3ER_]

Bulgaria

[@MiataMods]

Yeah I was looking for the coin one too but I couldn’t find it and I also wanted one which goes from 0.1mm to 2mm but the most go from 0.1mm to 1mm. But it is available if you look hard enough 😅

[@RY3ER_]

Yeah I suppose I'll stumble upon one eventually.. Currently looking on Ebay but I wanted one in milimeteres, most are inches. In the end it won't matter rly, just have to get one.

[@MiataMods]

If you want I can buy a second one and send it to you but the 0.1 to 2mm one was not cheap. I think it was around 20 euros. If you’re interested, visit my website www.miatamods.net and leave a message!

[@Iseekoutthetruth]

cool, where did you get that magnetic Socket from?

[@MiataMods]

Just from the local hardware store. Look for a “sparkplug socket”, that’s the official name for it

[@pelayo1009]

Any tips for taking off a stuck boot? I can’t seem to loosen it!!

[@looolcom]

Hey man, nice videos as usual. How come your miata ignite quickly, mine and other ones take 1 or 2 more seconds ?!!

[@MiataMods]

Could be a lot of things; Spark plugs, spark plug wires, coil-pack, battery, fuel filter.. Try this: When starting the car, turn the key to the "run" position but do not start cranking the engine. Leave the key there for a 10 seconds, then turn it the rest of the way. If that stops the problem, then it's most likely that the fuel lines are just losing pressure. Which could be the fuel filter, or it could be a slightly leaky injector. Neither is an immediate worry tho. If it doesn't bother you I wouldn't worry too much.. if it does bother you, replace the parts I've mentioned earlier and see if that helps. Good luck!

[@marvinorantes7837]

If by accident the wires are wrong is there a possibility that it can damage something?

[@MiataMods]

No it can’t damage anything

[@tommybraes635]

Isn't it so that the order on the coil pack doesn't matter? As long as 1,4 are on the right half of the coil pack and 2,3 on the left side?

[@MiataMods]

Technically yes

[@ipguyman108]

Excellent Excellent Mazda Miata video. THANK YOU....!

Where did you buy the red spark leads from?

[@MiataMods]

It’s from a local seller called ‘De Cabriohoeve’

[@akiwiinswitzerland6214]

MiataMods thanks mate... 👍🏻

[@Aladdin5cave]

Your engine oil might be a bit low or maybe the oil weight is not that suitable to cause that lifter tick. Mine sounds like that if the oil is low.

[@MiataMods]

I filled her up right before I started it so she’s not low on oil but the sound doesn’t bother me so I’ll just let her tick away 😅😆

[@Aladdin5cave]

MiataMods haha I don’t think I could tolerate the ticking. I’m sure you will find the problem, fix it and make a video about it lol

[@MiataMods]

Yeah that sounds like me 😂 It sounds a lot worse on camera.. with the hood closed you barely hear it 😅

[@richardsharma283]

Man my spark plugs look just like that, drenched in oil . But it’s all the valve cover gasket!

[@MiataMods]

Yeah if you replace that you are all good!

Sorry to disappoint you Sean but no ☺️ I am power hungry and I love the BOV sound so this will be “yet another turbo build” 😆 but it will be a good one!

[@seandejong5399]

MiataMods oh ok thats alright as well! But promise me to make it as step by step as your other videos, so we are able to follow along 😌

[@seandejong5399]

MiataMods or how about supercharger, since there aren‘t as many on youtube?

Yes I will make sure to cover every step of the way so others will know what to do! I won’t be installing a supercharger because I don’t like the wining noise 😅

Looks like you might need a valve cover gasket

[@MiataMods]

Yeah that’s probably what caused the problem.. got a new gasket already so I will do this job soon! Thnx tho! 👍

[@johnm.3278]

Blow out the debris around the plugs with compressed air, BEFORE removing the old plugs!

[@MiataMods]

Good tip but you have to have compressed air available tho

Should replace your valve seals my guy

Men I miss your videos! You are fucking cool men, thanks for your videos and teach how to do it :) Hey, one question can you recommend one cool torque wrench? (from amazon or ebay?) Thanks men! Good work!

[@MiataMods]

Haha thanks for the kind words! I can't recommend a specific brand but just go for one that's in the medium price range. A really cheap one will brake in no-time or the calibration will be way off. A really expensive one is not worth the money if you only use it a couple of times a year. I paid around 50-60 euro's for mine so I guess that in the medium price range.

This is why Subaru BRZ owners become former BRZ owners.
