i want to put new plugs in my 1992 wrx its got full s/s exhust and headers , induction kit and uprated fuel pump .

price is not really a problem within reason of cause just want to put the right ones in

thanks

 

i use ngk PRF6bs and they work fine (93wrx)

 

thanks anybody else

 

NGK's for me as well.

 

i went for the PRF7bs on my 1994 wrx running about 290bhp & runs spot on but i think the 6bs are good enough for upto 350bhp

 

Sorry yeah, I got the 7's as well. Im running around 350bhp.

 

were can i buy these guys

 

I found this guy the cheapest from everywhere i looked.

eBay.co.uk Shop ? CARPARTS BULBS and STYLING: Search results for PFR7B.

 

There the 7's by the way. Search his shop for 6's if thats what you want.

 

thanks very much

 

Pf 7's are best but while your at it get a price on pf 8's!! And get ready for a shock!!!

Just got some for my car and were talking more then £100
