Has anyone changed out there standard spark plugs and installed the Autolite XS-4164 in there 96 motor and how do you like them

 

Autolite plugs are as good as most. The only plug I use and recommend is BOSCH plugs. They seem to hold up better and get more miles. NGK make a fairly decent spark plug but I've settled on BOSCH spark plugs.

As a note, most of my experience with spark plugs have been with liquid cooled engines. Plugs for air cooled engines are a whole different ball game.

 

So easy to go to the HD parts counter and say...i want plugs for my bike. Pay and leave. Plugs are really not that magical...I put double platinum Screaming eAGLE on my bike and it didn't a damn bit of difference...

 

The thing is...........you go to the HD parts counter and buy 2 spark plugs and it costs you $10. Or you can go to your local auto parts store and ask for 2 Autolite 4164's and it costs you $5.

I run the autolites

 

I have run Bosch platinum in my bikes for twenty years or more, but my S&S motor recommends Autolite, which seem OK. I stopped using Champion and NGK for the same reason, that they both had poor screw threads and didn't seem to last long. They may be better now, but I will stay with my favourite brands.

 

How many miles do you get out of spark plugs? I know I have 20,000 on my standard HD plugs. I don't know if they were changed befor I bought it at 26,000 mi. but I check them and they always look good, I always think to white but not burnt in any way. My bike has a carb and has open air cleaner,pipes and torque cams, I figure the longivity is a phenomenon!

 

Service interval shows changing at 10k intervals. They can go longer or shorter. Cheap insurance to just change them out, they are so inexpensive.

 

Autolites are long lasting(platinum)

 

I run NGK but Autolit is just as good!
