Justin Posted July 4, 2005 Share Posted July 4, 2005 Do these look OK to you guys in the grand scheme of things? The other 3 not pictured look the same. They are HKS S40i (Denso) Quote Link to comment Share on other sites More sharing options...
paul mac Posted July 4, 2005 Share Posted July 4, 2005 its pretty hard telling anything usefull from the condition of plugs as there are so many variables but from the pics there are no nasty melted bits so i'de say they look OK Quote Link to comment Share on other sites More sharing options...
merckx Posted July 4, 2005 Share Posted July 4, 2005 They look good! Here's some useful sparkplug pics: http://www.dansmc.com/Spark_Plugs/Spark_Plugs_catalog.html Quote Link to comment Share on other sites More sharing options...
Alex Posted July 4, 2005 Share Posted July 4, 2005 Hmmm the whiteness *could* be a sign of things getting a bit too hot in there...but as I said in my FAQ it's pretty much impossible to read plugs as they tend to only tell you the last things that happened. What are your EGT's like? Quote Link to comment Share on other sites More sharing options...
b_have Posted July 4, 2005 Share Posted July 4, 2005 The correct way to 'read' a plug is to look at the inner base of the porcelain (usually with an eyeglass and light) Although if you are using pump fuel its a little harder to see a burn colour. A light tan colour indicates good fueling and plug heatrange. Quote Link to comment Share on other sites More sharing options...
