Do you need to put on dielectric grease on these plug when installing them?

To avoid confusion: anti seize is not recommended on the threads. On my Mazda 3, the torque spec (dry) was 10.8-14.5 ft-lb (depends on whether the engine block is steel or aluminum, mine is aluminum) Regarding dielectric grease, a small amount should be put on the porcelain region of the plug. Dielectric grease does not conduct electricity (never put it on the threads or distal tip). A small amount in the porcelain will prevent the spark from bypassing the proper route through the plug and arc over the surface.

Are these the same spark plugs as the oem ones? part# pe5r18110?

They are the OEM original parts for my 2014 Mazda CX-5. Spark plugs do not get any better than NGKs in my experience.

Will these work with the 2014 Mazda6s?

Yes. And they have been great so far. Highly recommend
