Is it ok to use NKG #BCPR5ES plugs vs. the recommended NKG #BCOR6ES. I live way far from any city and a motorcycle shop had these. The only difference is the #5 instead of a 6. Thank you!!
I live way away from small towns. I need new spark plugs for a 140 Suzuki Outboard. The closes I found within an hour was NGK BCPR5ES, the recommened ones were NGK BCPR6ES. Is the 5 closes enough to the 6? Thank you for your help up front.
