which ones and best place to get them from car is a my99 type r thanks

 

I have a 99 TypeR too... I use the NGK PFR7B... but if your car is only slightly modified, i would suggest NGK PFR6B

 

I have m MY98 type R running NGK PFR6B.

 

As said 6's for standard 7's if modded, the 7's run slightly cooler Got a set from here a couple of weeks ago, he does both

..... how often do you guys change your plugs?....

 

Had my Scoob 15 months and changed them twice, when i change the oil

 

crikey

sure they have a 3 year life span suposedly?

 

From experience the NGK’s lose their performance quiet quickly, clearly alot depends on a mileage and how far the car is modified. After 3 years I would suggest they would struggle to create a reasonable/useable spark.

 

Yeah they look ok when i get um out but keeps her running sweet and it does no harm eh

 

seen specialists service schedules that change every 18k... which seems quite extreme when my subaru manual suggests every 60K .. which i think is about right as the platinum plugs lasts a long time...

whats peoples view on this?
