Attached is the info for the plugs. The reason I'm concerned is because the engine is ticking pretty loud @ idle. I've heard this could be a normal occurrence but it still sounds kind of bad. The only upgrade I have is a k&n typhoon cold air intake. I have a few small oil leaks but the oil has even changed regularly with mobil1 and Amazon basics full synthetic and it is full at the moment. No check engine lights and runs decent just bad gas mileage lately and some slight hesitation. Thanks for the reply. Again any Info u have would help as I dont want to have to tear the engine apart or replace it as I'm kinda broke right now I between jobs.
