Spark plug NGK or OEM Volkswagen

FWIW, I just had spark plugs and coil packs done on my 2016 Jetta, $185 out the door at my local dealership

I had a 2012 Passat I drove for 10 years (after buying used with ~20K miles) and only just replaced two weeks ago with ~125k miles. I had to replace the alternator at one point and some other general stuff like spark plugs over the years, but that was it really. Nothing super expensive.

On Rock Auto Denso...Denso double platinum spark plugs for $4.32 each, but I would opt for the NGK Rutheniums for $8.32 each because they last longer and provide better combustion in these older engines

I went with the NGK rutheniums as they're also rated for 100k and were slightly cheaper on Rock Auto than the iridiums. Supposedly they maintain fuel efficiency longer over their life than iridiums

I run NGK on my 15. The car runs great doesn’t miss. I used OEM Denso 5339 but they lasted 10-15k but then I tried NGK 92182 and they’ve lasted bout 40k so I’ve had no issues with them both of them Iridium.

Stage 2 EQT E85 and NGK 91006 here, but I only order from NGK directly.

NGK Laser Iridium 94124 is the OE plug. Just stick with the OE Plug.

For spark plugs I always used NGK because that's what Motorcraft actually uses if I remember correctly. Autolites are complete garbage and always fouled out the few times I used them.

I bought these when I did my last tune up and plug swap just to try. I noticed zero difference in power or mpg.

If these are for a TJ (97-05) return them and get NTK (NGK). The 4.0 will not like anything else.
