I stopped by Advanced auto parts today to buy a set of NGKCR9EH9 for the F3.

The counter person typed in the NGK plug number and up popped an Autolite option to the NGK.

NGK CR9EH9 - $5.92 each
Autolite Plug 4302 - $1.48 each

Thats a savings of $4.44per plug and $17.76 per set.

I will let you know how well they work and how long they last.

 

NOOOOOOOOOOOOOOOOO DONT RUN AUTOLITES FOR THE LOVE OF GOD.

Seriously, return them and if you've installed them, rip them out and throw them away ASAP.

I know its for 250's (my wife has one) but I'm pretty damn sure it would apply to F3's as well.

 

my car f'ed up auto lites in it in like a week...my dads bike did the same thing...

 

Why are Autolites so cheap?

There's a reason for that

NGK or Nippon Denso

 

i've run Autolite coppers and autolite platinums in my Jeeps for probably 100,000 miles over the years.

some of the better plugs i have used actually. autolite coppers change once a year, they are about $1.50 each. autolite plats last much longer, but they are more.

 

yeah, a gallon of cooking oil is cheaper than a gallon of full synthetic......but guess which one I put in my crankcase.

 

dont be cheap buddie. +1 on NGK or NIPPON DENSO
