shortlid Posted August 11, 2005 Share Posted August 11, 2005 I usually use NGK or Denso copper plugs for my vehilces. But, my Mom now lives 3 hours away and when I do the job at 30k I don't know if I will be able to hit the next change at 60k. Should I put NGK or Denso Platniums in it?

Setright Posted August 11, 2005 Share Posted August 11, 2005 I would chose NGK, double platinium - or Iridium. Either is "expensive" like around $12...per piece, but they will last. A set of NGK "V groove" will also last 30k miles, but of course if you want something that lasts longer... Link to comment Share on other sites More sharing options...

shortlid Posted August 18, 2005 Author Share Posted August 18, 2005 Anybody put Plat. or Ird. in there SOHC EJ253 yet?? Link to comment Share on other sites More sharing options...
Buddythedog Posted August 19, 2005 Share Posted August 19, 2005 It's nice to see people doing things to help their parents out. Just make sure that your/her car uses plat. plugs or non plat. or regular old plugs. My former 97 Outback was platinum only. My 03 FOrester is regular plug only. I was told not to use platinum plugs in it, so I didn't. I just put in the Denso plugs at 1.87 a piece,and it runs beautifully. Link to comment Share on other sites More sharing options...
shortlid Posted September 16, 2005 Author Share Posted September 16, 2005 OK, I only had three hours so I changed the coolant in her '03 GT with that universal yellow stuff they are selling now mixed with distilled water. When I opeaned the cap there was this redish stuff all over the cap, the bottom of the overflow tank. Whe I flushed the rad with watter this stuff came out as well. I wonder if it was SOA factory isnstalled "magic treatment for phase I EJ25's"? Anyway I put Prestone water pump lube and cooling system treatment. Buddythe dog thanks for "Just make sure that your/her car uses plat. plugs or non plat. or regular old plugs. My former 97 Outback was platinum only.!" She had WORN "Crap"ion spark plugs in it stock. I swaped them out for with the regular Denso's. My Mom says she thinks it feels peppier! Why would they put these junk plugs in a Subaru, at 30k there gap was DOUBLE what it was suppose to be! If it's this hard on plugs CAN I go to the plat.plugs in the EJ253? I also replace the fuel filter with the Purolator. and changed the oil and filter. That was all the time I had so next time I am down it's ATF drain and refill, front and rear diffs, and brake fluid flush bleed. Link to comment Share on other sites More sharing options...
Setright Posted September 18, 2005 Share Posted September 18, 2005 Please keep an eye on the coolant for a while. Mixing types can lead to problems with the stuff thickening up. If you rinsed/flushed well, you should be okay. Plat plugs should work fine. Make sure you get double plat, though. The ignition system fires a blank in the opposite direction during the exhaust stroke. Link to comment Share on other sites More sharing options...
shortlid Posted September 18, 2005 Author Share Posted September 18, 2005 The Yellow ALL Coolant/ All Makes stuff is the ONLY thing you can buy at Wal-Mart anymore Prestone does not even sell teh green stuff anymore just the all purpose yellow!
