Spark Plugs

Sorry if this is a repost, I can't find anything about it when I searched. I have the water injection that I'll be installing here within a half an hour. It suggests copper spark plugs over double platinum. I guess for the temperature to convert the water into steam?

Anyways Autozone only has platinum plugs and wouldn't sell me anything else because that's what ford recommened. I went to the dealership and they were trying to get me to buy some single platinum (wire plugs?) that were 4.80 a piece.

To get copper ones with a 1.3-1.4mm gap am I going to have to order them or buy some and regap them? How much is a spark plug gapper cost? ANY advice would be appreciated.

It will be installed today either way, but for the fuel economy the coppers are suggested. Thanks.

It's nice that people are searching for stuff. But the golden rule is.
If my engine came with copper, i will put copper back.
If my engine came with platinum, i will put platinum back.

Kermit what the f?  AutoZone refused to sell you coppers because they aren't recommended?? Whoever that dumbass was deserves a good slap upside the head about 40 miles an hour.
I worked at the 'zone and i can tell you why.
I only sold plugs that came with the engine because i did not want the people coming back and saying I sold him the wrong stuff. If they wanted something different, I always ask you sure about 5 times. Like his dude came back pissed because the Bosch +2 had his vic running like crap. He wanted to show his ass and stuff. Then my coworker said, look i remember you. You know I would not sell Bosch plugs for a ford, i told your ass to get motor-craft. The dude look at pissed and walked out. :laugh:

Maybe, but the only advantage of platinum is that it lasts longer. If I had known how easy it would be to change my plugs, I would have bought copper and change them more often.
Platinum does not last too longer. Copper only last about 30k and platinum last about 50k. Not 100k like Gm, Ford,a nd other say
It might be but I have been hearing that for a long time. And seen proof on my GA car club. But Mr. Robert how long does each last?

It reminds me of the automatic transmissions that required no servicing.
From my owners book. Also my car and our malibu don't have a dip stick for the tranny.

Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss. If a
leak occurs, take the vehicle to the dealership service
department and have it repaired as soon as possible. You
may also have your fluid level checked by your dealer
or service center when you have your oil changed.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
 In heavy city traffic where the outside temperature
regularly reaches 90F (32C) or higher.
 In hilly or mountainous terrain.
 When doing frequent trailer towing.
 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
