    I'm still leaning towards the plugs. Running fake plugs that likely have little to no quality control can't be good. Some in the batch may run hotter than others, etc. Three of the 4 burnt up in 10 minutes. The OEM plugs in after that ran for at least 45 minutes with no issue before it blew. With more noise at idle after swapping the NGK OEM plugs, the damage had probably already been done and it was a matter of time after that.

    Not sure if you can tell from plugs if it's burning hot or not. Here were the NGK OEM plugs that were in her when it blew. Ski shut down at 45 mph so it wasn't at idle speed. Obviously the smashed one is the cylinder that blew.

    If it's reasonable to get gas tested, I'm more than willing to siphon some from the take and get it done. Probably going to siphon it out at some point and run it in my car. Probably has 15 gallons in it.

    I don’t know if I would be siphoning it out and running it in my car, do you have any photos of the porcelain on spark plugs?


    I also believe I read you bought plugs from Amazon, they run a pretty tight ship. I doubt you have fake plugs.

    It was a third party seller on Amazon. Seller: "Kaitlyn Deal". Looks like they've been removed from Amazon's list of sellers.

    If you really suspect the plug as failure, I would send it 1 to NGK and if found to be fake. Send Amazon the bill for motor

    Amazon provides a store front for huge numbers of third party sellers. A huge portion of the product volume sold on Amazon is not ‘from’ Amazon.

    Amazon does have a counterfeit products problem. They have been working on the problem but still lots of unauthorized and counterfeit products are being sold by third parties.

    If the seller listed is not Amazon, then the product being sold is not from Amazon. Even if it is being fulfilled from an Amazon warehouse.

    I'm with turboX. I would like to see ceramic on failed plugs. If there was ceramic in that cylinder, I dont care what anyone says, that could absolutely crack and explode that piston at 10,000rpm.

    But you still need to find out what damaged the plugs. Defect or something else. I believe if you had fuel electrical, pre ignition. Problem. You would have definitely noticed that in performance. Especially in a 4 cylinder

    Pics of the 'Iridium' Plugs. Sorry, I didn't keep track of which cylinder they were in. I believe the plug with the tip intact was cylinder 2.

    MR-1 guys: Would a 2005 FX-HO engine be a pretty easy drop in for my 2006? Would any electronics need to be moved over (ECU, or anything)?
