are these a good choice for my wrx import '95 impreza?

NGK PFR6B

 

There perfect unless your running around the 350BHP MARK

 

thanks pal,now i'll buy as i suspect they need doing!

 

i would switch to the 7B's if youre making more power then 280BHP.

 

have similar age car to you bud...ran with a new set of 6b's for 10,000 miles seemed great and then 'upgraded' to the 7b's..difficult to say if better or the same...???
paid £32 quid with delivery off ebay...

I tell myself car seems a lot sharper....LOL

 

cheers lads its a completly standard '95 wrx import and i believe they make about 260 bhp? i found a set on e-bay for £18 so it seems worth giving them a go for now.if i was to add a de-cat centre pipe and back box would i get a big gain in hp? and would i have to mod anything else ecu wise or just do a reset?
