Spark Plug Question
 

My 05 WRX is coming up 50,000ks and I want to replace the spark plugs.

I guess I want to stick with original plugs as no complaints so far unless anyone has any other recommendations and why I should swap for a different type.

My question is shall I just get the originals from Subaru or will they just rip me off with the price or can I get them from anywhere and cheaper. Does the gap come preset or wiil I have to check it and if so what is the gap??

Thanks

NGK PFR6B is what you need, comes pre-gapped to suit.

Ok thanks for that.

Supercheap have them for just under $20 each. Is that a reasonable price ??

Evolution R supply and fit from $100!

shop around to see?

If you have ever changed your plugs before you will go with the Evolution R supplied and fitted for the extra $20... well worth it in my opinion.. and i'm sure you may want a few of their other cheap upgrades at the same time...

Ok now I am confused :confused:

Just found a parts manual extract, attached, that says it is a PFR6G spark plug.

The NGK site says the same as you Rossco PFR6B and supercheap have them listed as PFR6B-9. Are these the same or different :confused::confused:

I think I will go straight to Subaru to avoid any mix up.

And pay 3 times as much?

Never changed them before but on research it seemed it wasnt to bad to do them yourself. Its always good if you can save a bit of money but not if it gives you a bigger head ache.

I will keep Evolution R in mind. I am going to see them this week anyway for something else.

Pfr6b-9 is pre-gapped to .9mm

Pfr6b is pre-gapped to .8mm

Performance difference is 0.

Your more likely to find pfr6b than pfr6b-9 on the shelf at general auto shops.

I used to do the pfr6b's for $15.00 a plug for club members - sorry I don't have wholesale access to them anymore since i changed jobs.
