Spark Plug Question

[Scoota G]

Hi Folks,

The last thing i want to do is sound like a man with a squirrel running up and down his pants but if i'm running a N42 Head and 280ZX Electronic Ignition what plugs should i be running? Cause the 280's run a different plug is all.

Hey scott the NGK catalog says

 

  Recommended plug        BP6ES-11    gap plug  1.1 preset

 

  Iridium spark plug          BPR6EIX-11  gap plug  1.1 preset

 

http://www.ngkspark.com.au/sparkplug_cars.php?PageMode=Results&Make=Nissan&Model=280ZX&Year=197919842.8LL28E

 

I run a L24 ,E88 Head, 280zx dizzy, 10mm top gun leads, MSD 6AL

And i use BPR6E that are V groved and the gap is set at 0.8

 

Went though heaps of plugs (and different brands) too find the ones that work best (NGK)

 

Hope this helps                                  Pauly

Ye I'm running the 6ES-11's but I'm thinking of trying a hotter plug as they keep fouling up.

I was reading the Hakosuka restoration thread on the JNC forums and he tried a few different plugs on his L28.

For a daily driver, 6ES is best. For a casual driver/infrequent use, 5ES.

also greatly depends on the condition of the motor, eg, a high or higher compression engine that over standard may require a colder range plug, whereas a low comp or tired motor will require a hotter range plug, compression plays a major role here, i just fitted fives to a triple webered powered l28 as it matched the characteristics of the motor better than sixes

Just read the article, thanks CDR, just wondering if anyone has tried the iridiums and if so how they found them, I'm going to replace with a set of 5's later and might just buy a set of 4's to try out as well, in the regular plugs of course not that rich LOL.

Yes I,ve used Iridiums ,cost me $120 for a set of 6 (wholesale price)

And they foul up the same as normal plugs .Waste of money for the older motors

They where made for new cars that you cant get to them easy

(removing manifolds etc too change plugs)

Stick to normal NGK,s and you can change them regularly aswell for peace of mind

Dont tear up money on Iridums and thats my 2c worth

Those that turned up to our last meet will recall my Zed was running like a pig due to fouled plugs. Removed and inspected they were very black and wet. They were Denso VW16R-A13's (Iridium) fitted by previous owner. Went to my local trusty Robbo's store and was told that the Denso's were not a good choice.

 

He asked me about how I use my Zed, which is I am lucky to drive it once a week and if it has points or electronic ignition. So for electronic ig & regular use he suggested the BP6ES-11 but since I have points & hardly drive it he recommended BP5EY. $3.95 each & Bobs your uncle.
