Best Spark Plugs for 2.5L? NGK V Power available?
Hi All,
Want to change to copper plugs for my Outback.
I've heard the copper NGK v-powers are a good choice,
can't seem to find them.
Anybody got favorites/recommendations for the 2.5 litre?
thanks.

I've used the +4's in one of my Subaru's (97 OB Limited) I did not find any difference between them and the NGK coppers. In fact, when I removed the +4's and looked at the end by the electrodes w/ a loop. You could see that only one of the 4 electrodes were really doing the work. I think you're better off just getting the copper plugs and changing them more often. Barring that the Bosch single electrode plugs if you don't want to change them as often. I have an FAQ here on changing the plugs:

I think the 6E are colder plugs.
i had the same problem too. i went to the store and said 5E-11 but they go your car 2.0L SOHC is 6E-11. but i was sure cause in the manual i copied the number from.
oh btw the "v-Power" plug u guys have seem to have differnt packaging and the colour is differnt!? the plugs that i got were silvery with a tint of brass-yellow. the plugs thats on this forum are like yellow!

NGK Copper Power V
I have 2000 2.5RS and recentltly pulled the NGK copper BKR6E-11 plugs I installed six monthes ago. They were almost as new and the gap.044 was still intact. I have enjoyed the performance from these plugs and they were a huge positive change from the champions.

The yellow and red packaging is from a 10 pack, silver is for the 4 packs.

can you explain the colour difference then? cause they really do seem metal rather then yellowish copper

Why would you say that BAN SUVS? My Dad has them in his Supercharged Miata and they work great. Though I'm not positive I believe the STI comes with them from the factory. I believe they are NGK IFR6B with the first letter designating Iridium.
