Here is some pics of the plugs Funds are getting tight. Oh as for the oil on the sparks the issue has been fixed. Ok if you guys say it is cheap then i will get new plugs also.
Doesn't look like he has much time to shop around, but a year ago I bought good plugs on Amazon sale + manufacturer coupon what come to few cents a piece.
Sometimes it pays to think in advance.
Thank for all the advise everyone I just have one question left about the plugs. The question is is the plug nothing more than a wire cable like the - & + cable to the battery or is the plug more complex than that?
100% difference after spark change I can't believe the ml320 ran so long with those shitty sparks. It response faster on take off, the cats is now silent which i did not expect, just hope i pass smog now.
Funny to read, that automotive spark plugs are just slightly over 100 years old.
Meaning we have people alive today, who were born before spark plugs come to the use.
Yet huge progress in design was made in one human lifetime.
I still remember replacing plugs every 25k kilometers and now you can drive on one for 200k miles.
Failed again 3 times now ,but i got new tags from DMV today Got a smog exemption here is proof i think i need new cats. But at 200 parts per million which is very small the Cats sensor does not care until it goes to 400 or higher.
Some USED cats, can yield you up to 300 dollars depending on quality of cat. The cat is made up of valueable metals such as platinum, palladium, rhodium and such and therefore that is why cats are expensive in the first place and why even used cats that failed can get you some money since the metal is most likely still good. They just recycle that stuff anyways.
So an ML probably has at least 4 cats I think? You can probably get 1000$ for all 4 if they are good on the market. And then just go with an aftermarket cat that has warranty and keep replacing it everytime it breaks after 3 years
