Spark plug Bosch or NGK

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

Today I installed new spark plugs and the misfiring situation has improved significantly but is not completely gone. If I pull up the RPM too quickly the misfire counter goes up.

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.

I just replaced my oem densos with some Bosch plugs that were labelled as being pregapped 1.1mm. I wanted them to be 1mm and checked with a gauge and Lo and behold they were already at 1mm. Whacked them in and improved my fuel consumption immediately.

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

I've used Autolite plugs in my stock 2011 for 6 years. I wanted to try NGK's so I recently installed a set of Ruthenium NGK plugs. I haven't noticed any difference between the two brands.

Damn $40/plug, I have a nissan altima 2012 and got the most expensive one at $30CAD/plug NGK iridium laser and it was out of necessity as cheaper ones was out of stock during lockdown.

I just put Bosch plugs in my 13 Veloster turbo and got 300 miles and it started missing replaced with the ngks no issue since
