Ngk plugs

I am rumming r6061-11 stock number 2773 i have been told there is a cheaper version of this in ngk that is just as good any ideas ?

 

NGK # R5671A-9 or -10 work great for us and alot of people, but we do tune on the safe side.

From what I understand its a great plug unless you are running on the ragged edge of a tuneup, then the 6061's are better.

 

Do you index the 5671A10's or do you just throw them in because the ground strap is 180deg. from the 6061's? Yes the 5671 are much cheaper I buy them at $1.42-1.50 a plug

 

where do u buy those plugs

 

you can also try the b9es. . we ran them for years and never had a problem. I even went back to them because the 10's cost so much.

 

I had trouble finding them.I went to spark plugs .com or something like that.The confusing part was mine just had a 2 digit number on them.The race plugs have a R on the numbers,I bough a scrillion of the awhile ago and cant remember the web site

We run the B9es. They are available everywhere up here because its also a popular snowmobile plug. We buy 200 at a time and can usually get them for $1.75 a pc.

 

i've gotten all my ngks at napa. they usually want the stock number (different than the actually plug number) but if they are nice they will cross reference it for you. hope this helps!

 

I recently bought B10ES plugs at Auto Zone for $ 2.39 each . No quantity breaks from my local store .
