tundwgn Posted April 2, 2006 Author Share Posted April 2, 2006 I went with NGK's One Step Colder Plugs. Like them. Suby uses NGK for a reason I do believe. Link to comment Share on other sites More sharing options...

SLegacy99 Posted April 3, 2006 Share Posted April 3, 2006 Anyone know the cost of NGK Platinum Plugs? Link to comment Share on other sites More sharing options...
sgt Posted April 4, 2006 Share Posted April 4, 2006 platinum is more than iridium most of the time. IIRC, usually about 12-15$ vs 6-8 Link to comment Share on other sites More sharing options...
Xenonk Posted April 4, 2006 Share Posted April 4, 2006 been reading a lot of the NGK vs Denso.. NGK just seems to work better with the Subarus..seems that no one really have consistent luck with Denso spark plugs.. it's a real hit or miss with them.. nothing wrong with NGK, it's OEM Keefe Link to comment Share on other sites More sharing options...
SLegacy99 Posted April 4, 2006 Share Posted April 4, 2006 When I had my plugs replaced, Subaru told me only NGKs. Period. Link to comment Share on other sites More sharing options...
