@joebrez NGK makes the motorcraft OEM plug its just a different label & box. I also went with my owners manual & gapped all mine to 0.054.
@Final Impact i did a bunch of searching around on here for opinions & feedback on which plugs guys seem to like best. Final conclusion on my part was NGK was they way to go.

What PN finally went in? Like I said, if its not double platinum electrode and ground strap, I don't see a big advantage. Where is the dead horse???

@joebrez i held the OEM motorcraft right next to the NGK IridiumIX and they were identical except for name on them & a bit of color. The reason yours didnt look identical is because the iridium laser isnt the OEM motorcraft plug. The iridiumIX is.
@Final Impact the part number i used is the TR5IX 7397.

@Final Impact is that the part # for the Motorcraft plug from owners manual??
@joebrez thats strange that NGK says interval on the IX is 40-50k miles as the Motorcraft OEM are 75k miles.

I believe the laser iridium is NGK's top line of plugs and they were almost $5 more per plug. Either way, im glad i did research before just buying something & i feel i made a good informed decision.

I agree that it is strange.
When I changed my plugs the first time back in 08, the common thread on 6club was go Laser vs the XI. Later, people like myself and others found the performance of the Lasers degraded quickly and the engine wasn't happy. For security and cost, I went back to Motorcraft which IMHO is still the best bang for the buck on Rock Auto. If they indeed are the same plug (NGK vs Motorcraft), buy what ever is cheaper...

It also good be a Mazdaspeed part type thing. Take the springs for example, the springs are made by Eibach and look identical. However, the drop is slightly different due to a slightly different spring rate. That is what I meant by NGK making them, but not exactly the same thing.

Ya they very well could have a slight difference to them even being made by the same company in the same plant. Maybe next time im due for plugs i will go back to the Motorcraft ones.

No doubt!! If they are only meant to be in there for that long i will certainly go back to OEM which are 75k intervals. Ive only put on 15k kms since install so ive still got a while to go yet before worrying about that again.

Finally done. The car feels more responsive and quicker jump from a stand still. I did the spark plugs, EGR Mod and TB Bypass Mod. I broke the battery plastic tray where the hook to secure the battery clips on and the T thingy that everyone seems to break when doing the TB Bypass Mod.

Here's what my plugs look like.....Time for a HOT shower.

Thanks for the forums... I couldn't have done it without you guys.

What is the proper spark plug gap?

The gap setting is different for each vehicle but most are somewhere between 0.028" and . 060". Consult the owner's manual or Champion ® catalog to find the recommended setting for the vehicle you're working on.

What should I GAP my NGK spark plugs?

NGK doesn't recommend adjusting the plug gap more than . 008" in either direction. Beyond that slight adjustment, the ground electrode and center electrode won't align properly, hindering spark plug performance and drastically reducing plug life.

What happens if you set spark plug gap too small?

What happens if the spark plug gap is too small? If the spark plug gap in your vehicle is too small, the spark won't have enough exposure to the fuel mixture to properly ignite it. The spark generated by a smaller spark plug gap is sometimes too weak to start the engine.

What happens if you gap your spark plugs wrong?

Incorrectly gapped spark plugs could cause engine misfires. Corroded spark plugs could halt the spark altogether and, again, cause misfires. Broken spark plugs could, you guessed it, cause misfires AND if pieces of the ceramic enter the cylinder, could cause far worse issues down the road.
