My Mom has a '03 Legacy GT Sedan with 29k on the clock. I am going to swap out ALL fluids, and change the plugs at 30k. She lives 3 hours away so I don't know were I will be when she hits 60k. should I put NGK or Denso Planiums in it? :?

I have heard that if you EJ25 does not have plat. plugs facory DON"T put them in?? Anyone confirm or poo-poo?

When I took the stock "Crap"ion plugs out thery were well worn at only 30k!!
Why would they put Champion junk in a Subaru. I ended up puting copper Denso U-grooves in and it is more peppy. :twisted:

Looks like TWO pleple are running NGK plat. are they in EJ253's, how do they look after 30k?? :wink:

NGK Copper V-Power are the best, IMO, because they have a better conduction over iridium and copper, but the platinum will last the longest. As far as not putting factory platinums in, I don't know :?
