All I can say is WOW, but then again, you will NEVER find any of my saw's intakes looking like that and if I was the customer, I would have taken off the shroud and had a look-see prior to but then that is just me (and probably you) but not the average consumer. Not that I would ever have any 'dealer tech' work on my saws in the first place. besides, if I need any OEM parts for my Echo's, I just have the parts counter supervisor order them and I pick them up, other than spark plugs which as of late seem to be getting counterfeited by the Chinese. I only use yellow boxed NGK's btw.
I will say I've had very good luck with the HF 'Torch' plugs and I presume they are Chinese. The 'Torch' plug I have in my HF pressure washer is the original one and other than gapping it rarely, it's been in the motor since it was new, 10 years ago and I use it a bunch. In fact, it's on it's second pressure pump. Oil gets changed yearly and the AF gets blown out and that is it. Amazing little Predator motor.
