spark plug model no.

 What is the spark plug model number for a 1.6 98 mk2?
I saw on ebay and dandycars people said it’s BKR6E11
and in http://www.techguys.ca/howto/spark_plugs.html here it says BKR5E11
which one should be the right one or are they just the same?
does halfords sell same quality of NGK spark plugs as on ebay? (the packaging is different, but model number seems to be same)
 
thanks guys

 BKR6E-11 are the ones apparently.
