The link you provide to the Amazon page selling the "Denso" ignition coil is probably counterfeit. The seller, "Naymar Best," is registered in Pakistan. The price for coil is extremely low considering ToyotaPartsDeal has them for $115. How does he sell them for less than half? I have purchased TWO coils from this seller and installed one on my truck last week. I don't expect it to be OEM Toyota but the reviews are stellar with reports of the coils working fine, so I'll take a chance. But don't fool yourself, if you want OEM you need to buy from a dealership or authorized Denso vendor. "Naymar Best" in Pakistan is not an authorized vendor.
