Spark plugs
 

I have a wrx 1994 . It's that time to get it is sevise again am looking to get new plugs .
What one do I need to get it upgrade

throw some iridium plugs in, just put some in mine 03STi nice smooth burn

three pin with 50 amp fuse for your 'sevise'.

NGK PFR6B are recommended jay
Or PFR7B for highly tuned big power cars

take no notice of the pathetic fat lad he's nothin better to do


Use just regular old coppers and change them every xxxx NGK are good and come pregapped for standardish power

I would always gap them - the "pre-gapped" plugs are quite often out by varying degrees in my experience - I always adjust mine with feeler gauges to 0.65mm.
6's are fine for standard or up to 320ish I'd say.
For more than that use 7's and for big power cars (probably 500+) I think you're looking at 8's for best performance.

Hi Jay

As above PFR6B should be OK for yours needs,depends on mods and depends on the boost,power what are you running and will be running,but usually I recommend to use PFR7B

Hope this help

Thanks,Jura
