Spark plug NGK or OEM Mazda

I bought a 19’ Premium at 17 it’s a great little car beat the shit out of it for 4 years straight and it runs amazing still. Handles well in the winter as long as you have clearance it’ll get you there in one piece. Regular maintenance along with trans fluid change, spark plugs, brakes, diff fluid change. I’d recommend a cpo premium . Great value.

I had this very same problem where on my 07 V6 the acceleration and power was off. I had replaced my spark plugs with NGK Iridium plugs and after dealing with the horrible performance I decided to change them out for OEM platinum (copper) plugs. This made a huge difference and could immediately tell a night and day difference. Regained the torque and power that was missing.

I've run the NGK ruthenium in my sierra with the 6.2 and they ran great but I notice they aren't the right gap.

You use a **NGK BR2LM.**

I’ve been running NGK Ruthenium for a year now with 0 problems. Supposedly they last longer and are more stable with less dispersion according to NGK. Going to stick with them instead of Iridium or Platinum.

I have ngk spark plugs and I went with z1 high ignition coils

if you don't want to pay for VW boxes, NGK ruethiums are a killer deal on rock auto, I've run 2 sets through out alltrack without a hiccup, about 60K total.

I do NGK 6510 one step colder. I do 0.025”-0.026” gap. I had a shop do my last set since I didn’t trust myself. He accidentally did 0.022” and I put them in and they’ve been fine. The other set is 0.018” and idk if ima put them in. Gotta change the one step colder NGK’s at around 15-20k miles. I usually change mine when I start seeing high spark retard. I’m BT 93/E40 with aux.

Additionally I would endorse the use of a Champion or NGK plug. The LG/Torch/random Chinese plugs are a crap shoot. I see tons of failures on them as well.

I’ve gotten fake NGK on Amazon before it’s very possible
