[sold my malibu]

where oh where the hell do I find them?
I have done some research on which ones to get low impedience,peak hold,
I also have heard warings from some others out there.

I have looked online and at a large chain auto parts store for Lucas 550s,i believe the other choice is denso.does anyone know of a online place ?

Or the part # and brand That I can have my favorite parts guy look up.

by the way that AFM of mine was being finnicky today till I run the shit out of the car and it was fine for the rest of the day.I had just cleaned the k/N airfilter (according to directions)it sat 12 hours inside before I put it back on.I'm thinking it got a little gummy in there perhaps.
I don't really mind going through a few problems with the car as it one sure way to gain knowledge ...painfully at times but going forward still.
