hi, i've a forester sti with the 2.5ltr engine thats gonna get remapped by JGM in the near future & i want to run with a cooler set of spark plugs - the standard plugs are NGK ILFRR6B's & i see NGK dont have a set of ILFR7B's in their range....

what plugs do i fit in my 2.5ltr engine (same as impreza 2.5ltr sti) ????

 

They'll be ILFR7H plugs you need.

cheers Nick - do u know wot gap i need them at ??

 

0.7mm - can't remember if they were pre-gapped to this so double check them.
