Spark plug NGK or OEM Mazda

I buy the OEM ngks every time. I find cars CAN be picky about what plugs you get.

I picked up a set of new VW Atlas sparkplugs of FB MKTplace locally for a good price and before I tossed them in one of my cars I decided to verify all of the spark plug differences and to reserve the research here are my results:

I have mentioned numerous times here to remove Torch plugs and replace. One would not run fresh out of the box (WEN). Replaced it with an NGK and it's been purring ever since.

If I had a choice between a resistor type NGK plug and a non-resistor Torch, I'd take the NGK in a heartbeat.

Laser iridium or ruthenium from ngk

Yeah, I use NGK laser iridium. I got a friend that has a m6, m5 v10, and uses those, it's good

Ngk's. First thing i did was get the original plugs out of my beamers and put in the ngk ones. Widely considered one of the best plugs for your engine.

I'm running NGK Iridium NGK LTR71X-II 1 step colder but I am tuned. Been running these sparkplugs since the car had 5000 km. I have 45000 km now in 8 years and a half and I have changed 3 sets as it is recommended to change them a bit sooner than 30000 km on a tuned car.

Be careful where you buy your plugs. There are counterfeit NGK plugs out there. I found out the hard way. I purchased off of Amazon. Mine melted before I could even get a mile in to my session.

Velas NGK, nunca use Bosch, terá problemas.
