Default Re: ngk spark plug for slant head

The "p" is for the extended tip, it works in my slant head 48cc. With ngk the lower the number the higher the heat range, run it and do a plug check or chop as it is sometimes called and look for signs of heat related problems.
Your results may not be the same,Greg
