Vturbo Posted November 9, 2015 Share Posted November 9, 2015 so, I'm planning to run around 1.4 bar on a TD04, what heat range plugs do people use? Thanks! Quote Link to post Share on other sites

Socks Posted November 10, 2015 Share Posted November 10, 2015 @AdamB Grade 8 or 7? Pros Cons of each in your opinion? Quote Link to post Share on other sites
Vturbo Posted November 10, 2015 Author Share Posted November 10, 2015 (edited) I ran 7s at 1 bar on ct9 hybrid..had a few people tell me 8's for the td04 setup. Edited November 10, 2015 by Vturbo Quote Link to post Share on other sites
Stu Posted November 10, 2015 Share Posted November 10, 2015 BKR7e - gap to 0.8mm or so. They will run a lot more than 1.4bar with no problems and they are miles more forgiving that iridums Quote Link to post Share on other sites
AdamB Posted November 10, 2015 Share Posted November 10, 2015 @AdamB Grade 8 or 7? Pros Cons of each in your opinion? Their 7's mate, the grade is in the part number. 8's are way too cold for a td04, wouldn't start using 8's till like 400bhp or running exotic fuels. Or as Stu suggested, run the copper core plugs, but they need changing more frequently. Quote Link to post Share on other sites
Amjad Posted November 10, 2015 Share Posted November 10, 2015 How long are coppers good for? Changed from Iridium to Copper a few months ago on mine Quote Link to post Share on other sites
AdamB Posted November 10, 2015 Share Posted November 10, 2015 (edited) I'd probably change them every 25k, or every 2 services. I change my Iridiums every 25k just to keep things fresh. Inexpensive service item that gets changed regularly rules out any problems in the future Here's a little piece of tech info. Spark plugs, common item and often overlooked.http://www.ngk.com.au/spark-plugs/technical-information/heat-range-explanation Edited November 10, 2015 by AdamB Quote Link to post Share on other sites

Chief Quimby Posted November 22, 2015 Share Posted November 22, 2015 I use standard plugs from 4age 16v, 0,6 gab on my 400hp 5efte Quote Link to post Share on other sites
Stu Posted November 22, 2015 Share Posted November 22, 2015 (edited) Yeah they run the same plug, would think your running a colder BKR7e or even an 8 for that boost? Edited November 22, 2015 by Stu Quote Link to post Share on other sites
Chief Quimby Posted November 24, 2015 Share Posted November 24, 2015 Me ?, i use the bone stock ones from 4age at 2,3 bar. Quote Link to post Share on other sites

GP82 Posted November 25, 2015 Share Posted November 25, 2015 Horse power level and boost pressure ratio do play a part in selecting the right plug heat range, but actually it's a combination of all, more so the heat thats created from combustion. For example you could have a high compression engine producing 180hp but would still require relatively colder spark plug then a lower compression engine producing 280hp.

For example you could have a high compression engine producing 180hp but would still require relatively colder spark plug then a lower compression engine producing 280hp. That's the issue, peak cylinder pressures and temperatures. Because the 4E is so low on compression there's no need for cold spark plugs. Quote Link to post Share on other sites
