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).

I just got a set right from the dealer for an M104(stock copper, non resistor Bosch plugs). $2.50 each for that price it doesn't pay to shop around.

Indeed...I find the dealer near me is quite reasonable in regards to plug cost...I picked up 6 for 13 bucks...non resistor

Well, I appealed to my dealer, told him I'd buy 12 if he'd give me a deal.
So, he dropped the price from $4.65 to $2.50.
That's good, but it's too bad you have to go in with your negotiation face on just to get a fair deal.

My local NAPA in Jax just burned to the ground! Glad I stocked up.

I guess it depends on the dealer, we bought six. List price was $2.95 or $3.95 but they knocked it down to $2.50 without me having to ask.

Speaking of resistor issues. I went to the dealer to pick up 12 for the ML V6 and he said they were $18 a piece list, but he could discount them to $13. That's $156 for my non-mathematical bretheren. I passed.

Yep the ML would be the M112 V6 that is a different animal. Those plugs only need to be changed every 100k though.

If you think thats bad price out a set of plugs for an XJ8! Jag part prices will make even the most seasoned S600 owner weak in the wallet!
