Hey juice, same goes for me as w/ whitewolf. I can't find a good number for mine Your 50 2t number may give me a place to start from. Which plug are you using? at 10-14 bucks a pop I realy dont want to buy a handfull of "samples". And, whitewolf if you use search canyon to look for the correct plug you may have some luck. I found all kinds of info on NGK, and Denso applications but couldn't find a crossover for the custom plug I am using. You probably can just google to the site you need but I find surf canyon will cut to the chase in three-four clicks.
