You can, but they're two grades colder than the stock equivalent NGK Iridiums; BKR6EIX

Is that a better choice? colder the better ???

Better for hard-pushed race engines with turbo or nitrous. A colder plug has a shorter electrode which reduces the chance of detonation & is better for heat transfer but the short electrode can get dirty easier & it can cause starting difficulties from cold - some old race engines had two sets of plugs for starting & getting the engine warm & then another set for race conditions. A warm plug suits pootling about town a lot near idle engine speeds, if this is your typical drive, it's prob best to stick to standard.

Thanks, I will stick with standard NGK's

I thought about changing them but in the end stuck with stock ones.

Well, those 8-grade Iridiums are exactly the plugs I've got to fit with all the changes I'm making to mine at the moment (including NOS!), so I'll let people know how they work out for general driving.
