    Hello all.

    What brand are the OEM spark plugs for a 2010 srt8?

    This is a good one coming hopefuly yall can advice me.

    OK my vehicle sometimes smokes. LOL

    Sometimes when I stop at a light etc i see smoke soming from the car. It is not over heating and it does not smell like anti freeze either. I did stop by the mechanic and he thinks it might be leaking oil. But could not find any visible leaks. He adviced i change the intake gasket which i will this weekend.

    any ideas? Not sure if it matters but my left bank oxygen sensor is giving me the check engine light.

    thx

    Your best bet is to take it to a dodge dealer and that would take the guess work out of it, and in the long run probably save money.

    so the smoke is coming from under the hood or the tailpipes? does the smoke have an oil smell to it or perhaps an exhaust smell? (I saw you stated it doesn't smell like coolant.)

    This is an iridium spark plug. It will work fine in a 6.1 engine. It is an upgrade from the excellent OEM platinum plug that lasts up to 100,000 miles.

    Iridium is arguably eight times stronger and six times harder than platinum. It has a higher melting point of about 700 degrees compared to platinum.

    Platinum spark plugs wear out faster than iridium spark plugs. Iridium plugs are said to be more durable compared to platinum plugs, up to 25% more, and can last up to 120,000 miles.

    The price of iridium varies from that of platinum because one is a more valuable metal with higher quality than the other. The average price of iridium, as of 2020, was around $2,550 per troy ounce. As of March 2021, the cost of iridium took a surge to $6,000 per troy ounce. Meanwhile, platinum currently costs around $1,015 per ounce, making iridium almost six times the price of platinum.

    Here are some pros and cons between the two types of plugs. You will have to decide if the additional expense of iridium plugs is worth it.

    Pros Of Iridium Spark Plug
    • It is harder compared to platinum.
    • It uses less voltage in operation.
    • It lasts longer than most spark plugs, including platinum.
    Cons
    • It is relatively expensive compared to platinum and many other spark plugs.
    Pros of Platinum Spark Plug
    • It lasts longer than the regular copper plug.
    • It prevents and reduces the build-up of debris, especially in the spark plug hole.
    • Platinum spark plugs cost is relatively cheaper than iridium.
    Cons
    • Compared to other spark plugs, like iridium, platinum is not the strongest spark plug.

    Great explanation. Thanks.

    It smells like regular burning if that makes sense. Not antifreeze. It seems to be coming from the front to mid bottom of the car. No oil drips. The mech did see some dried up oil around the screws that hold the intake manifold down. So he thinks it is a really small leak somewhere around there. White looking smoke.
