Bosch Platinum +4 VS. NGK Platinum

roman_s · 03-16-2011, 01:19 PM

So I wanted to get people's input on Bosch Platinum +4 and NGK Platinum

Which one you would recommend over the other (not other models)

ttam · 03-16-2011, 01:22 PM

I believe most people on here would go with the NGK

psre08 · 03-16-2011, 01:27 PM

I doubt you'll notice a difference. They're both OEM. I use Bosch.. no complaints. But I agree that most ppl here seem to prefer NGK for some reason.

roman_s · 03-16-2011, 02:21 PM

Yeah thats what I'm thinking... NGK.. I heard Bosch has some problem in mid-range firing... any difference between the 4 prongs vs 1 arc prong??

Never had issues with Bosch plugs, 90k km

Max Power is all about maximizing load and timing without misfiring, no? So unless you can increase load or timing using the NGK plug over that of the OEM Bosch plug, then why change plugs? Is there any real data out there?

FWIW, iridium is the better choice vs. platinum

drilla2212 · 06-12-2014, 10:46 PM

Ngk iridium or bust

#Tee · 06-12-2014, 11:00 PM

I recently replaced mine with NGK. From what I was able to gather there are 3's out there with NGK oem and Bosch oem.

Have Bosch Iridium - no problems. They replaced the original NGK Iridium plugs and there were no problems then and still going fine.
