Plugs?
 

Time for new plugs, wondering what you guys are running or recommend.

Thanks

the factory ones are good for 100k, imho i would stick with factory. how many miles you got on your z?

Nvm I jumped to conclusions. It was hesitating hardcore under throttle which made me think plugs which I thought was strange based on the cars mileage. However it recently stopped and hasn't done it for a day or so which means it's something else. I'm thinking coil pack?

try the maf sensor and check your air filters. If not maybe a bad batch of fuel? Is your z a dd?
