To All,
I own a 97 LX450 with 94K on the ODO. I have changed the spark Plugs 38,000 miles ago with the Bosch +4 type, I wanted to replace them with OEM's and after speaking with someone who works for Mercedes Benz about my attempt he advised that I should not replace the Bosch +4 type as they are good for at least 100K or more as they have what is referred to the ceramic electrode that will never wear out which is different than regular platinum electrodes, to confirm our brief conversation I compared both spark plugs and I can see what he is talking about, asked another friends point of view on the matter and he agrees that they should not be replaced yet.
What are your thoughts/advise on my course of action guys ?
Thanks
Al
