NGK - What's the difference?
Upgraded to NGK TR55's this weekend and found NGK PTR5-C13's already in the car. Very very small electrode that comes to a point. What are the
C-13's and what's the main difference between the plugs?
thanks,
later,

Found out the difference on the NGK web.
PTR5C-13 is a Premium Platinum, tapered seat, resister type medium heat special design plug with a .52 required gap and the
TR55 is a Tapered seat, resistor type medium heat with a .59 required gap
If you need the site it's http://www.ngksparkplugs.com/techinf...tnumberkey.pdf
The site is being updated to include the TR55 info (I called them)

The factory actually put some NGK plugs in for a while a few years back due to a supply issue or something with ac/delco.

Actually the TR55's are plain vanilla copper core plugs. They only cost $1.50 each!
They will not last nearly as long as platinum (or Iridium) plugs... But, the copper is an excellent conductor, and they have a larger electrode (since copper is cheap), so the theory is that they will provide a better spark.
But you do need to change them out more often.

I believe the TR55's also have the Iridium center electrode which holds up much better than platinum
TR55ix = iridium (next best spark, moderate heat dissapation, moderate longevity due to thin electrode required for good spark)
TR55vx = platinum (least quality spark, moderate heat dissapation, longest lasting)
