The Smok V8 Baby X4 replacement coils are designed for use with the Smok TFV8 Baby Beast vape tank as well as the Smok Big Baby vape tank. These coils will produce large amounts of vapour, to support this we recommend pairing them with a high VG e-liquid, that is 60% VG or higher.


  • Smok sub ohm vape coils
  • Quadruple coil build
  • Will support a 45 - 60W power output

Utilising a quadruple coil design, along with organic cotton wick for improved flavour, the coils feature a 0.15 Ohm resistance, best used between 45 and 60 Watts.


  • 5 x Smok V8 Baby X4 0.15 Ohm Replacement Coils

Important information about Sub Ohm Vaping:

Any coil that registers below 1.0 Ohm, is known as a sub ohm coil. Recommended for advanced vapers only, they'll require more power to use properly, which will be provided by an advanced vape kit.

With these coils larger amounts of vapour will be created, to support this we recommend you use e-liquids that are 60% VG or higher. Due to the larger amounts of vapour that is created, we advise that you do not use an e-liquid that has higher than a 6mg nicotine strength.

Best out there (28 January 2023)

I had tried many coils and almost gave up with Smok, until I found these. They last well, they allow you to taste everything from the juice and the price is great. The longest I had used a brand or style of coil was about 2 months, only due to not finding a great sub-Ohm coil, until I found these. I have been using them for about 4 years now and won't switch to a different one because they're so good. Well done Smok.

A nice coil (04 October 2021)

A great tasting coil, but I found they didn’t last long.

Best V8 coils available (08 April 2021)

I was ready to throw my TFV8 Baby tank in the bin and never buy another Smok tank again, having tried just about every available coil there is.
The X4 turned it around completely, they work great, last reasonably well for the price and they actually let me taste all the flavours the liquids are supposed to contain.
By far the best, and the only usable, coils for the TFV8.

Still a fave (29 February 2020)

Been using these coils for the past 2 odd years and still swear by them. They're just as good as the others yet also last longer than many of the new coils for newer tanks they've released

Ummm (30 June 2019)

Hi guys always use vc for my coils as don't trust anyone else to provide genuine item, however the last few orders I have noticed that the coils don't seem to be lasting as long as previously, don't know if you have a bad batch or changed your supplier?? Anyway I have ordered some more and hopefully these will be better.

What's happened Smok?! (24 April 2019)

Been using these coils (X4's) religiously for well over 18 months, always been a good balance between cost, flavour and cloud production. I work from home, so hammer coils all day long, the X4's generally lasted me around a week (2-3000 puffs or there abouts) Recently the last 3 blister packs have been terrible, not had more than 2 maybe 3 days at best before they've had it, same with the T8 & T6's. Never change my setup particularly so can only assume they've changed something somewhere or have skimped on materials. None of the other reviews seem to be recent, what's gone wrong Smok.
As things stand will never use again and certainly cannot recommend.
Just brought new tanks, 'Horizon Tech Falcon King' & 'Aspire Cleito pro' as a result.

Going The Distance (16 March 2018)

Using these coils in the Baby Beast tank on a Smok Alien, after spending a fortune on the oct and quad coils as recomended and having the dissapointment of abruptly burning through them in a matter of days on changing, I decided to give this coil a go and give the BB tank one last chance before I ditched it for one of my old tanks.
I am happy I gave these coils a go, ok there is still some faffing, but not only am I getting longer use out of them compaired to the other compatible coils, I am getting a smooth throat hit with nice cloud with little to no flavour change over the time, which saved this mod from the drawer of no return, the coils last me on average 2000-2400 puffs at 60/65w before you can tell they are going, which is good, because lets face it this tank is a pain in the ..... to change coils on. However, I have been peircing the wick, this is key if you want a decent vape from the Smok coils, this method works well with this coil ( harder with the quad and oct coils) amd by using a large pin to puncture the wick going through the outer wick into the core/coil wick with a little bit of jiggling and then closing the holes you made in the outer wick inlets up by teasing the cotton a bit once done, allowed for better saturation and a much better vape. I personally think the coils for the Baby Beast are packed way too tight with the outer wick and then the inner wick that wraps the coils not allowing the juice to pass through easily.
But, Smok still really need to sort their coils out.
Its just my opinion.

Very Good Coils (23 January 2018)

I using them in a Smok Big Baby with a chimney extension on an Alien 220W mod. So far my favorite Smok coils for the Big Baby as I prefer a lower wattage vape. I have been using them at 50W with a 50/50 juice mix and get roughly 8-9 days out of one before I have to replace. One tip I picked up is to poke a very, very fine needle through the cotton on the sides and for some reason this seems to make the coil last a bit longer. I don't know the science behind this but it does seem to make a difference for me.

Great coils when they work (29 July 2017)

I recently bought a pack of these coils and sadly had some issues with a few of them.
I thoroughly primed them and even let one soak in my tank overnight but even at the lowest wattage on my Smok Alien 220 they would immediately burn,smoke and spit juice.
I watched practically every YouTube video to see where I may be going wrong and did everything suggested and I tried different eliquids at different ratios but to no avail.
I have got one of them working and I must say it works well with lovely flavour and good sized clouds,I just wish they were all like that. An electrician friend of mine took the bottom off of one and noticed that the quality of the wiring was rather poor.
VapeClub has been wonderful with me over this and sent me replacement coils for the Crown Mini as I requested instead of the Smok ones,a discount for the Crown Mini tank and a load of freebies. I can not rate VapeClubs service highly enough,their customer service is second to none and as for postage times...well let's just say they must have wings lol.

Best coil for flavour in the baby range? (30 April 2017)

I've been using my smok alien kit for a year now and have tried the full range of coils available in my Baby and Big Baby tanks.The Q2 coils are basically useless in the Alien Mod with the Baby tank as not enough air gets the coil and it burns basically above 25w,they work a bit better in the Big Baby tank but barely last 15-20 mls of juice before there is no flavour. The T8 and T6 coils are great for cloud and running at high wattage,but after about 10-15ml of juice the flavour fades fast.The Q4 i find to be the best for flavour and after 60ml of juice the flavour is still going strong.

Great but wish they lasted longer! (05 February 2017)

I've been using my smok alien now for about 8months and find it great, best mod i've ever bought. I have used the whole baby tank range of coils and find them great however my only con would be that 15-20mls or 500 vapes(puffs) later which can be around 3-5 days i'm changing the coil. They don't last very long, considering i've got a few other vape devices which coils will last around 1500 vapes which is 3 times of the life cycle of these coils. Is there a way that you could make a coil last longer please? Other then that, faultless. 9/10

By DB from Surrey

Good coil, but how long will it last?! (07 January 2017)

I've been using the octuple 0.15 and sextuple 0.20 coils for a while in my Baby and Big Baby tanks. They're both great for flavour and clouds, but they don't last very long (three to six days depending on juice used). Hopefully, these will be longer lasting?! I got this coil in the pack with my Big Baby and thought I'd use it up. First impressions are really good - it's sufficiently airy without cooling things down too much (so better than the 0.40 coil in that respect for me), and there's a lot of flavour and cloudage. If it gives me longer than the alternative 0.15 octuple coils, I might switch to this type - it's a similar experience, but usable at lower wattage. Hopefully, that will see me save juice, and battery/coil life. For the current performance alone though, a very high 9/10 (point knocked off for the possibility of the short lifespan...!)
