can any body please tell me wat the difference between these plugs
Denso
k-20r-u11
and k-20pr-u11
i googled and googled and came to noe that k-20 was the ideal plug for baleno, now wen i bot em the shop keeper asked me if i wanted k-16r-u11 but i insisted on (k-20r-u11) dats the codes which came in my mind at that time i didnt noe plug codes could be so complicated. he gave me thoose, which are in toyota packing, i got them thinking packing doesnt matters. and i got wat i wanted
