What a pain!
I know to use only non-resistor Bosch plugs in my '91 103 motor.
So, I check Fastlane - not available, back-ordered.
I check another mail house - same story.
I check a 3rd place in New Jersey - THEY HAVE THEM.

So, I order them, and the next day they arrive, shipped from a warehouse
10 miles away from me in Dallas. BUT THEY ARE THE RESISTOR TYPE - WRONG PART NUMBER.
Well, I pay $8 to ship them to New Jersey on an RMA.

A few days later, I check the 2nd supplier, in Atlanta - THEY HAVE THEM.
Well, you know the rest - they arrive the next day from the same warehouse down the street from me. WRONG AGAIN.
So, now I gotta ship them out if state again, for another $8 lost.

Oh me, sometimes dealer 4X markup doesn't seem so bad.


I wonder if we are going to be SOL with the older non-resistor engines?
Will the resistor plugs work for at least a short while?
Are poor idle, and fouling, and increased emissions, and reduced fuel mileage
the only drawbacks; or can the ignition system suffer over the longterm using resistor plugs?

grrrr again,
DG

and stock up

You can also use the NGK non-resistor plugs if you can't find the Bosch. They are out there, you do have to hunt for them though. I had a couple McParts stores tell me they don't make non-resistor plugs any more, and they wanted to argue with me when I told them they were wrong.

McParts store are correct--as regards American cars--which is all McParts stores are good for.

I just checked, Fastlane has them in stock right now for $1.70 each.

These are a pretty regularly stocked item, I think. If they're not in stock, try checking back in a couple days or email Phil.

Wrong.

Most McParts stores can order the H9DC0 or H9DC. Just tell them to type the part number in and order them. Likely, their catalogs list the incorrect plugs.

Hmmm... the local independent place I get all my parts from can have the H9DC0's in stock next day (as with most stuff).
