Curious if they will look the same as the ones I got when you get them.Ordered Mazda plugs which just arrived.
How many times per vehicle life do you change the plugs? 1-2 times 99% of the time. I figured it ain't a place to save 70 bucks.
That was a wrong guess. Based on post #47 from Anchorman, two recommended OEM spark plugs listed in our owner's manual both are resister type. PE5R-08-110 is NGK ILKAR7L11; PE5S-08-110 is DENSO ZC20HPR11. OEM plugs do have MAZDA mark and its part # printed on the ceramic insulator.⋯ I've read here that apparently Mazda's plugs can provide resistance(?) readings while ngk do not. (or something of this nature?)
Toyota V6 trucks are known to have NGK and Denso plugs...at once in the same engine. Look it up

Purely for info, that is the Mazda parts website.
So question...I didn't get around to doing the spark plugs over the weekend as my garage was hotter than hell and I was pretty done after doing the AT shifter switch.
So for replacing the spark plugs, do I need to disconnect the negative battery terminal first, and do I need to use that anti-seize gloop? I did not think I did, but thought I should double-check.
Not sure that you really need to disconnect the battery, though I always do when I work on my car. Since I use a torque wrench to tighten the spark plugs, I don't use anti-seize lubricants since they affect the torque readings and I could end up over tightening the plugs.
Not that I know of. Once you're done, reconnect the battery and you are good to go.Perfect. Thank you for this answer. I will be using a torque wrench as well, so will forego the anti-seize.
Do I have to do anything special when I reconnect the battery, or will everything be good to go?
PE5R-18-110 and PE5S-18-110 are basically the same spark plugs. "S" is standard spark plug but "R" is resister spark plug which adds a 5kΩ resistor in ceramic insulator to suppress ignition noise generated during sparking.
Agree with that. I have a hard time believing Mazda...tiny Mazda... Came up with brand new plug tech.
