spark plugs

what is the best spark plug for 2.5 hawkeye wrx impreza,

ngk 7bs mate nearley everyone runs them

thanks bud

NNOOOOOOOOOOOOOOOOOOO!!!! Standard heat range plugs for your car are ILFR6B but If you want the colder plugs, you need ILFR7H plugs which are listed for the Evo and a number of people run in their Hawkeyes

i'll look in to this

hawkeye runs a completely different plug, iridium and of different size (longer) to the more common, standard plug is NGK ILFR6B off top of me head but can double check in morning as i have in stock, its possible to get grade 7 plugs but they are not listed as for subarus and run a smaller gap 0.6mm as to 0.8mm, i would not bother with the grade 7 plug unless running highly tuned high boost engine

LFR6B are the standard plugs in a 2.5 as they are a longer reach plug
The cooler grade plugs that I run in my 2.5 are NGK LRF7AIX

so it's NGK ILFR6B standard or NGK LRF7AIX for cooler grade

Careful, now go eat your hat lol

I run ILFR7H (EVO 9 plugs) this is the plug to use as a direct replacement for the standard hawkeye ILFR6B

Yeah they are if you are running a tuned hawkeye, if not then the ILFR6B will do.

Like jonny says unless your running a tuned hawkeye, more boost and bigger turbo I wouldnt bother using the 7 grade plugs, just use 6 grade plugs.

they are the wrong plug all together, the plug best for yours is ILFR6B, you DO NOT need 7s for the power yours is running the standard turbo will max at around 280bhp
