Spark Plug Heat Value

JadeyBlitzen · January 30, 2009

hi guys! i'm changing my plugs to iridiums and i'm quite confused by the different heat values of plugs. the standard heat value is IK16. but the lowest available heat value for iridiums is IK20, which is the next available range.

what could i expect if i install plugs of a high heat range? they have four heat ranges available and they are all higher than the stock value.

iridium or not...if your climate and type of running requires a certain heat range...i would say it's better to stick to that...

maybe iridium heat ranges work somewhat different to the standard ones? :unsure:

As i know copper plugs only last 10000km and Iri ment to last 100000km, other difference is iri has better throttle response, for Turbo cars Iri is better if ruing stock boost, if u runing more boost its better to use cheep coper plugs and replace them in every 5000km, i heard most of Sl tuners always prefere stock plugs,

I also heard its ok to go 1 number higher heat range and its safe too, if runing nos 1 number colder, so why dnt u replace plugs with stock IK16 ? its cheep and safe too
