Re: Can i use Iridium Spark Plugs with regular ones?

i am using iridium for center & stock for L-R .
cold start is excellent now . bike idle at 1k rpm easily . i have a 2014 ns200

Thanks so much vvk1999,

Now i will use NGK Iridium LKAR8AI-9 for centre and regular NGK CPR8EA-9 for side plugs.
Already got them and bike has just crossed 10K Kms so will get them installed soon.

Regards

It shows the engine oil and combustion burn. The ground electrode and center electrode shows lean burning . The outer ring of the spark plug is much colder since the heat is dissipated through the head...so due to the cooling effect you will see combustion deposits on the outer body ring...if you go on a drive of about 30~ 40 Kms of steady speed of 50~70 Kmph, these deposits will reduce. It is the comparative heat difference between the plug metal and combustion chamber that makes it happen...if the deposit becomes more, then you should check if it is dry or wet...dry means rich AFR and wet means engine oil seeping through the rings..
Good Luck..

It's good that you've replaced your spark plugs. From the looks of it the center electrode is completely blunt and your ground terminal tab is bent inside, suggesting improper care on both the plugs.

Periodically clean the plugs, and adjust the gap only if necessary.

Cheers!

Hi! I am a new two wheel user. So learning the basics. I have a Aprilia SR 125 scooter. I want to install a Iridium Spark plug for better mileage and better cold starts. Can I use NGK Iridium CPR8EAIX-9? Stock is Bosch UR3DC. Thanks in Advance.

I dont think that spark plug will work for sr125 . Its a 125cc machine why stress it more . Keep it stock & enjoy the ride
