Autolite 4164-4PK Copper Resistor Spark Plug, Pack of 4

I'm an Autolite guy (kind of like being a Chevy or Ford guy) and always will be. They always perform well in every situation unless some issue is causing them to fail. I got these for my street bike that gets some pretty good use year round - I've run NGK before and have had no problems but Autolites always run great in all my cars, hence my bias.I digress...Gap was almost spot on 0.040" and the washers and diode threaded on easily. Makes Black Betty run like a bat out of hell...

Only received one plug, not a four pack. Got a refund but will have to reorder. I am assuming the description is wrong.

These were teh perfect spark plugs for my Harley Davidson motorcycle. Great price too.

Thanks it's perfect came early couldn't ask for any better service

hard to say how nice this spark plug is. it has spark and fit so i guess it works just fine.

Very unhappy because only one spark plug arrived in the package when it was supposed to be a pack of four. Also, the packaging for the spark plug itself was somewhat damaged. I really don't want to go through the time and hassle of returning one spark plug--and I want to order more of these but am concerned I'll only get one at a time for $4 each. Was looking forward to installing these in my '99 Honda Shadow for a tune up...

Highly recommend these quality plugs to any Harley owner, but then again I'm a Ford guy so Autolite is a household name. For some reason these plugs feel nicer to me than NGKs or Champions, but I could be biased. I think plug brand comes down to personal preference, like auto manufacturer. Should note that these require an 11/16 plug socket, not the typical 5/8.

I ordered a 4-pack of plugs for the insanely low price of $2.65. The price seemed very low, but it said "4-pack". I only received 1 plug, so that explains the low price, but I do need 4. So I need to order again.
