Title: Grey Motor Spark Plugs Post by: Burnsy on July 21, 2004, 09:37:49 AM Does anyone have the different plug numbers for grey motors for the different manufactures eg Champion NGK Motorcraft Holden?
Is there any difference between them and are there any different grades of plugs available that are particularly recommended? Thanks, mike Title: Re: Grey Motor Spark Plugs Post by: gp on July 21, 2004, 07:33:50 PM Hi Mike,
You can use Bosch W10FC, NGK BP-4, Denso W16S-U. Hope this helps. Cheers, Graham. :) Title: Re: Grey Motor Spark Plugs Post by: zulu on July 22, 2004, 04:34:51 AM Graham, Or anyone, do you have the listing for Preslite brand plugs, as I have a box full of # 14 82 knowing my luck they will be lawnmower plugs.
Title: Re: Grey Motor Spark Plugs Post by: Jodstar on July 22, 2004, 05:16:42 AM There is a good article in the N.S.W FE/FC web page
that might help,it also describes a variation in spark plug reach as the early heads used shorter plugs. ::) Title: Re: Grey Motor Spark Plugs Post by: Burnsy on July 22, 2004, 10:57:05 AM I have found that I keep comming across boxes of cheap plugs at different places ($1 each) and want a definative list so I don't end up like Zulu ;)
Title: Re: Grey Motor Spark Plugs Post by: fastjbav6 on July 22, 2004, 12:46:30 PM The 132 & 138 take different sparkplugs.
I'll look up the part numbers and do a cross referrence for you Mike. Regards Seb Title: Re: Grey Motor Spark Plugs Post by: Burnsy on July 23, 2004, 04:31:43 AM Thanks Seb, would be good to have all the numbers in my wallet for reference next time I see some.
Jodstar, could you post a link to the page you are talking about please I can't find it :'(. Title: Re: Grey Motor Spark Plugs Post by: Jodstar on July 23, 2004, 06:26:28 AM Sorry Burnsy,I had the wrong site. The address is as
follows...http://www.geocities.com/ssehcc/plugs.html It is the South Sydney Early Holden Car Club and a good article written by Alan Trass with another on ingnition timing. Cheers Jodstar :) Title: Re: Grey Motor Spark Plugs Post by: robbzfc58 on July 23, 2004, 07:44:43 AM something from "vesta"spark plugs tech specs aug 1957 their codes were simple to understand..i guess others use codes that mean something too??

Got a pic of me current car on my profile though ;D Hopefully will get a better one on Sundays run. Update on what I have found out: 138 Grey NGK BP5S, Champion J10YC, Bosch W10BC 132 Grey (FE FC only, not FX FJ as it seems that the earlier ones had a different reach of 3/8 rather than 1/2) NGK BP4, Bosch W10FC The number realtes to the heat rating, with Bosch and Champion, lower number equals lower running temp and with NGK higher number equals lower running temp. The site that Jodstar identified suggests that with running on fuel with no lead in addition to higher road speed combining to decrease overall engine running temperatures, we should be opting for lower heat rating plugs. Any comments or observations from anyone who has tried this or actually knows about this would be good ??? Question still stands for which is better for a older smokey engine though. Title: Re: Grey Motor Spark Plugs Post by: robbzfc58 on July 23, 2004, 12:23:10 PM your onto it burnsy.....hot for oily motors & cold for over heating motors........toldya it was simple :-/

Mac: "Downsize" http://www.stuntsoftware.com/products/downsize.htm PC: "IrfanView" http://www.irfanview.com Both of these offer simple methods to create a copy of an image, reduced in physical size and JPEG quality to get them down to reasonable sizes. cheers RET Title: Re: Grey Motor Spark Plugs Post by: fcfromscratch on July 23, 2004, 12:59:13 PM Hi Burnsy,
I can recommend irfanview as a good cheap tool for reducing picture sizes for web posting..... I'll show you how to do it sometime...... Brad Title: Re: Grey Motor Spark Plugs Post by: fastjbav6 on August 17, 2004, 12:34:38 PM Burnsy,

For long trips or in hotter areas cooler plugs than the originals are probably worthwhile. If, like me, most of your driving is the 10k each way daily commute between home and work (in chilly Canberra) the orginal hotter plugs are probably the best bet. With the cooler plugs my grey motored EJ ran like a pig for just that bit longer. Replacement of the 72C thermostat with an 82C one helped too. If I was driving to QLD next summer I might swap the plugs and thermostat for cooler ones.

I looked at the plugs I pulled out of a 132 FJ motor I recently sold, it had 3 different plugs in it!! It has Champion J-12Y, an AC 46, and another plug with no markings. This one has a flat porcelain 'tube' with two green rings but no writing whatsoever, I wonder what that one is??
