Default Alternative Spark Plugs?

I was going to put new plugs in today but all the motorcycle shops around here are closed on Sundays. I tried napa, autozone, and pep boys and none of them had the NGK IMR9a-9H Plugs or the Denso IUH27D plugs.
Does anyone know of an equivalent spark plug that they might carry. I dont want to have to wait until tomorrow after work to get my bike put back together. Thanks

Thanks for the answer. I am definitely not putting the old ones back in. It was bad enough trying to get them out without the tool that came with the bike.
I guess I have to wait. I hate waiting for anything

Yep, most places carry the autolite. I know Advance does because I just had to get them for my magna when they didn't have the NGK.
The auolites for the F4i should be the 4302. Make sure you gap them.
The ones I got for the Mag were $1.99 each.

and its ok to put those in instead of the iridium was. If it is why would anyone pay 12 bucks per spark plug. What are the pros and cons here

Yeah, it's ok to put them in there. Same with regular NGKs that cross to the iridium type.
Iridiums are supposed to increase service life and they conduct electricity better.
Is it enough to make a difference? That's up to you, man. lol..
If you want to go with what's recommended, then by all means... enjoy your iridiums. Do other F4i owners use standard plugs? Sure they do. Many will argue that if the manual says to use iridiums then you have to, but it's not the case. The F4 calls for a standard plug, and fuel injection certainly doesn't require iridium.

Well, if you replace the standard ones more often, won't you be getting a "newer" "better" spark more often?

Hmmm....
I'm gonna use that excuse as to why I changed my standard NGKs for no reason after 6yrs.
My prior reason was "because I was bored", but your reason sounds way better.

Well if you cant tell a difference other than the frequency at which you change them im going for the cheap ones. Chances are I will sell the bike before I need to change them again anyways. Sooooo who wants to buy an F4i
