Which NGK spark plug is better/correct?

Shazmonkee · 06-23-2011, 04:32 PM

I went on NGKs website to see which one I needed to purchase for my car. I have a E92 328i and the site gave me two products:

#ILZFR6D11 and #LFR6AIX-11

Which one is more suitable for my car?

AlanAZ · 06-23-2011, 05:53 PM

If you go to RealOEM

http://realoem.com/bmw/showparts.do?...17&hg=12&fg=05

you'll see that the ILZFR6D11 plug was ended by BMW in 2007, it's replacement PLZFR6A11S (the plug I'm running) was ended in 2009.

Current part: NGK LZFR6AP11GS from 12/2009 BMW part 12120037663

Shazmonkee · 06-23-2011, 06:21 PM

Lol point of posting here is to find the answer without having to go through all that trouble but thanks for the info! Anyone else?

AlanAZ · 06-25-2011, 11:18 AM

Duh. It was right there on the RealOEM page, under the Bosch:

NGK LZFR6AP11GS from 12/2009 BMW part 12120037663

Shazmonkee · 06-26-2011, 02:36 PM

Is that interchangeable with a 2007 328i?

AlanAZ · 06-26-2011, 06:49 PM

that RealOEM page above is for a 07 328 e92.

So is there any downside to using the old plugs? like the old ILZ? Cause im doing my plugs soon and im starting to get confused. Rockauto.com has the old ILZ for 9.96 a plug.

AlanAZ · 06-29-2011, 11:33 AM

Updated plugs provide a more powerful spark, which translates into slightly better performance and fuel economy. When I put in an updated plug, I noticed a bit more mid-range power.

I just got my plugs from the same site and they had the PLZFR6A11S for 9.xx a plug too. Are they out of them?

Just looked again and the only NGK plug they still show is the ILZFR6D11 for 9.96. I guess they must be out of the PLZ. Great so old model plugs are going to suck

I doubt they are going to suck, per se. The ones I replaced were the previous model that you found, and honestly I can't tell any difference in performance and my old plugs were stock as far as I could tell. (63xxx miles) I also did all new coils at the same time so I wouldn't be too worried about it.

ska///235i · 08-09-2011, 07:00 PM

any part # for the coils for n52???

MaximusJ · 08-10-2011, 06:17 AM

Coils: 12137594937

MaximusJ · 08-10-2011, 12:42 PM

BTW, this is where I found the cheapest plugs out there.

Cheap plugs because they were superseded 4 years ago -- discount or be stuck with them.

Shazmonkee · 08-13-2011, 06:25 PM

So #ILZFR6D11 is superceded by #LFR6AIX-11

They worked fine on my car before so I dont know why its so bad to replace by the same plug? The plugs were updated for updated versions of software of my car. Since I dont have that software, it wouldnt change a thing for me to get the newer ones.

Am I wrong to think that way?

MaximusJ · 08-14-2011, 07:22 PM

I see... Im still on my original coils; being at 47k rpm... So ILZ should work just fine I guess.

Should have went for PLZ tho... Oh well...

Shazmonkee · 08-15-2011, 11:25 PM

Thanks AlanAZ

ska///235i · 08-17-2011, 10:21 PM

i have a 325 so should i get the PLZFR6A11S?
where can i find these for cheapest price?

isnt PLZFR6A11S the same as ngk #5987???
i got info from a ebay item....
http://cgi.ebay.com/ebaymotors/NGK-5...a#ht_918wt_856

if it is then advance auto parts have them and they always have 40% off, making the plug under $8

can anyone confirm if ngk 5987 is the right plug?

5987 doesn't appear to be an ngk part number. Did you check realoem for the latest part numbers there for a 325?

MaximusJ · 08-18-2011, 08:28 PM

Here's what my realoem part listing is for 325 plugs. No active part numbers so that's where I got confused and ended up ordering wrong plugs.

03 Spark plug, High Power NGK ILZFR6D11 6 03/2007 12120032137 ENDED
