Spark Plugs - 1.4 Multiair

[mikejj55]

I know the owners manual states using NGK IKR9F8 spark plugs - but - I noticed elsewhere in a 2015 NGK catalogue that Fiat for the same engine is using IKR9J8.

 

Is there any advantage/disadvantage of using IKR9J8 or should I stick with IKR9F8 (which is the same as for the Alfa 1.4)

 

Any views/experience

 

Thanks

something to do with the electrode design appears to be an update so presumably the new version is the best bet?? but I don't know for sure as I'm no expert

I'd stick with the 9F8's - as per Rosso sounds like just an update but you never know. What year is your car? I've just bought some 9F8's off an ebay seller for £38 for 4 all in....

Hi Nello,

2012 SR+Nav.  Yes I have seen the 9F8 for similar cost but the 9J8 are over £50 per set.  Just seen on another forum the same question raised with a response from NGK saying it is just a new catalogue number being introduced gradually so the retailers can sell old stock of 9F8.

Anyone know the Fiat part number for the 1.4 MultiAir NGK IKR9F8 spark plugs?

 

Are https://www.shop4parts.co.uk/?name=store&op=Details&ProdID=3818&sku=185494 these the same?

Those were the plugs I had seen as well.  The Fiat part number for plugs for my 2012 MultiAir is 55210685.  The other part number 55249868 is greyed out when I put my VIN number into Fiat Eper.

 

So I would assume the plugs are IKR9F8 (and happy if they actually tuned out to be IKR9J8)

I've emailed Shop4Parts to confirm mike - will let you know here......

[mikejj55]

Just received a set from Shop4Parts and they turned out to be the latest IKR9J8

[Nello]

Sounds perfect then Mike - thanks for the heads-up - I'll order a set.......

[Nello]

Fit your plugs Mike? Any issues - I presume the engine cover just pulls off the MultiAir.............

[Nello]

Yes Engine cover pulls off but I did not expect the plugs to be buried so far down in to the block! No socket set I have can get anywhere near them................... If you have done yours - what did you use?

[Nello]

Just thought I would add this handy little guide from the Alfa lads as you also need to remove the breather pipe on the MultiAir to replace the plugs......
