Well few weeks ago I installed bosch platinum spark plugs +4. It was good until yesterday I was reading this website http://vbxmaxima.8m.com
and found him saying that bosch could cause serious damage to your engine. It happend to his friend! Because of that I couldnt sleep the whole night Can someone tell me if using bosch is ok or I have to throw them out and get NGK. Daniel B Martin, and other maxima.org members please help.

 

I got the answer. I am going to buy ngk 5 heat range right now. I am afraid to keep bosch.

 

i have NGK in my car which was replaced 6 months ago and thats what is suggested by Nissan since its only one aproved. Must be platinum tipped head and they last for 60k miles.

 

...when I couldn't beat my wifes stock SE. There was a change with the NGK's imo. I think there's a reason Nissan used these plugs.

 

use oem plugs

 

Ths Direct Injection system of the Max is bullet proof, not much can be done to improve it. Bosch, Iridium, the only thing they may offer is longer interval between changes, but nothing in terms of power.
