Spark plug NGK or Denso

NGK Lazer Iridium Plugs is what I got to replace them in my car. I believe those are what Mazda OEM plugs are, but it’s just cheaper to buy the NGKs from a part store.

use NGK spark plugs, the best ones are the PFR6Q

Denso or NGk for anything and everything preferably dual ground spark plugs. I would get them rockauto as they have the best price and you can get the OEM brand.

Get the right dual electrode spark plugs, Denso or equivalent. They’re cheap, around $5 per plug.

Spark plugs are only $15 for Denso iridium plugs (providing the longest life) and they take no more than 20 minutes to replace them.

Pick up some genuine Audi R8 Red-Top coils (not kidding, much lower failure rate) and some fresh NGK Iridium spark plugs.

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.

They run just fine on stock setup. Changed mine 6 months ago once the car was at 30k miles and actually managed to snap one of the plugs in the head ???? Carefully managed to get it out though. No noticeable difference from factory plugs.

My brand new out-the-box WEN 3500 would barely start until I tossed the Torch and replaced it with an NGK. It now runs as designed. Too many others have had similar issues and that's why Torch is widely regarded as junk.

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.
