What spark plug would you recommend for my CBR?

[Westy_mate]

Hey guys just a question, Would you rather recommend NGK CR8EH-9 spark plugs or CR9EH-9 in My Honda CBR 1989 R mc19?

Thanks!

Your bike original specs would have run the CR8 spark plug.

I think you'll need more than one. Just a guess.

Yup, 4 x NGK CR8 EH-9 Plugs for those... the 9's are too cold for normal use.

what if i already have one CR9 EH-9 In there? should i just put 3 more or get 3 more CR8 EH-9's?

Its a brand new CR9 EH-9 i just bought... and these spark plugs are $22 a pop so i dont really want to go buy another one
