Hi,

I will be servicing my MY94 WRX soon and was wondering what people thought of the above spark plugs.

Also, If i get these would would be the best HT leads to go with them.

Thanks

Dave

You can't go wrong with NGK PFR6B's and 7B's, standard plugs
AFAIK you will have coilpacks and not HT leads in your MY94.

Hi,

I have NGK PFR6B's in my 94 WRX , gap set to a tight .07 mm ruinning with a VOS chip.

Plugs seem fine, took them out the other day to check condition after 5000 miles and are still ok.

I have tried the Denso (PK22PR8) which am told these are equivilant to NGK PFR67's which seem to run ok as well..

cheers

Mark.
