As recommended here and from Nissan, I'm getting ready to put new spark plugs into the Mada (I'm about to turn 100,000 miles). Planning on using NGK Iridiums. Does anyone know what the gap shoud be?

I put them on almost 9K ago and was told that they (NGK Iridium 9) were pre set from the factory.

Don't gap them. Iridiums are already preset and gapping them = damaging them. ;)

Advanced Auto has the best price I've seen anywhere.

good to know, most warn about factory gap, and say you should check, but as usual I will go with the CA guru's advice.

I put Bosch Ir spark plugs on my Armada. They told me that this was a huge NO! Is this true!?

Ok.

This is what they told me, "Moonlight (my truck) will start running like ****. Then the SES light will come on as codes for multicylinder misfire start occurring. Then unburned fuel will start dumping into the catalytic converters resulting in a catastrophic event: explosion: fail safe mode: NOT GOOD!!!"

Can someone help me make sense of this?

I've been running Bosch Platinum +4 for over 50k miles now... Hmmm, she still starts up good in the morning and runs strong all day. :)

Thank you so much!!! I have been worrying quite a bit about that. :)

But, I am curious where that idea came from because I have seen it mentioned since I started researching it....

dag speller where did you get this information about Bosch spark plugs in your research just asking

LOL Honestly, I don't remember the sites. I would just Google "Bosch spark plugs and Nissan". The person that told me the information that I posted works for Nissan, though. So, I was looking for a bit more objective information.

all,
along the same lines do these trucks have coil packs... right? so would it be a good idea to change the packs (wires too) along with the spark plugs??:confused: i guess to buy the plugs you would go to "a store" that carries that brand & just ask for the armada ones (5.6 li)?:confused:

thanks!!:);)
hope this is not a thread jacking, not meaning to:o

No need to change coil packs unless one has failed. There are no plug wires to change.

thanks!!

It's really easy, just time consuming... You just unscrew the coilpack, pull it off, and use a Spark Plug Socket to change the plug. My engine hood is over 4' from the ground so I found it more comfortable to just climb in and lay across the radiator to change them.

Amazon.com has NGK PLFR5A-11 (6240) for $8.97 and free shipping with Amazon Prime.

However, they limit you to 5! I tried to go and buy 3 more after processing out, but it did not work so now I need to go find 3 more. %$@%$#^%#

10mm socket for the coil packs. I have a little scaffold I picked up from "The Poe" when they were on sale ($20). Makes reaching in the engine bay or the roof easier.

Have a variety of extensions and a universal adapter. The one nearest the passenger seat is the toughest to reach. Due to the Aluminum Heads, many like to put a touch of anti-seize on the threads. Torque is only around 12 ft/lbs.

The service manual calls for 18 ft. lbs. torque.

In same predicament as bigzell, me too, is shopping for plugs with this 07 mada (w/ 103k mi.). aside the NGK's mentioned, I am curious of the Pulstar DG11 (tho I know nissan says NGK) if anybody has tried it? It is advertized as it increases Hp, torque, better throttle response, etc. Hey, who wouldn't like to have those... Any ideas before I plunge into it?

I changed my plugs out last night took about an hour. I put the Platnims back in. The iridiums were pricey. Cheapest I found were $17.00 ea.

I bought my NGK LFR5AIX-11 Iridiums for $8.48 each at www.sparkplugs.com. I don't recall if they are a sponsor here, but are on one of the Titan sites. Local store wasn't much higher. I recall one person recently had bought the Pulstars and had one or two fail. NGK is a proven reliable winner, not worth changing what works.

Wow!

I just looked up the plugs on-line from my local parts suppliers, and they get pretty expensive!

My Stealership told me the plugs should have been changed at 60,000 miles in my 2005 Armada SE. :confused: (I bought it with 85,000 miles on it)

But, I'm getting really bad gas mileage. (263 miles to 23 Gals. = 11.4 MPG :( )

So, I was looking at changing my plugs to get this back in check. Looks like for a few bucks, and an hour of time, it may be worth it.

Here's what I found from my local supplier.
From CanadianTire.ca:

NGK G-Power Platnium 2-pk. LFR5AGP $10.09 CDN
Comments : 0.044" - G-POWER - MFI

NGK Iridium 1-pk. PLFR5A-11 $19.09
Comments : OEM/OES - 0.044" - LASER PLATINUM - MFI

Bosch Platinum+4 2-pk. 4431 $16.09
Comments : DO NOT GAP - GAP IS NOT ADJUSTABLE - MFI

NASCAR Advantage Xp Iridium Spark Plug, 2-pk. NXP5325 $17.09
Comments : .044 GAP

I'm getting hosed on the NGK Iridiums compared to your website. Have to see how expensive shipping to Canada will be. :bow:

Note: only one kind said don't GAP them yourself. The rest listed the GAP required, or the GAP they come pre-set at.

I would stick with the NGKs

I would avoid the Bosch in the +4 configuration, I had issues with them in another car, the car felt sluggish with them in

I was reading through this thread but couldn't figure out which NGK's are OEM. Does anyone know the part number or model of the NGK that's OEM.

Thanks in advance.

Thanks Spyda!!! I figured it was that one but wasn't sure. According to Courtesy Parts, the OEM for the 2006 Armada is the Laser Platinum.

NGK Iridium 1-pk. PLFR5A-11 $19.09

Found these for $9.00 each. NGK Iridium Mark IV.

Took less than an hour, but needed long needle nose pliers to retrieve the socket off the plug each time as the rubber sleeve in the socket would stick to the plug, and then the socket extention would pull out of the socket each time I installed a plug. Very annoying. I guess I need a new extention. (too well worn)

Also put some never-seize on the first few threads of each plug. Made tightening them seem too easy.

Blame Canada,

Do you mean NGK Iridium IX not NGK Iridium Mark IV?

Does anyone use the laser platinums? I went in to a couple places today to pick up some iridiums but none were to be found.Buddy said the laser platinums were a step up from those an were like 17.40 each
