Why were you advised not to use the NGK pfr7b's?

PFR7B For the win.

he just said iridium are better plugs,apparently they run cooler and take power increase better.

 

cheers guys

ngk 7's it is then

at least i aint gotta shell out £50 for them iridium ones

 

ive just had PFR7B fitted and car runs alot better, it pulls alot better with no hesitation, but iirc my mechanic mentioned these plugs as they work at a lower temp, meaning cars running big boost.
My plugs werent too bad and even they were the PFR7B and the cars had some essentials added lol but i would recommend them.

 

thanks be fitting them the weekend then

What is the equivalent of the PFR7B for the hawkeye?
It currently takes the long reach NGK ILFR6B plug , but there doesn't seem to be an ILFR7B.

Answered my own question now - its an ILFR7H, same as fitted to the EVO 9
