Hey guys, I was wondering what do you guys think about changing the spark plug wires. I have a 2000 300 with 90k on it. I am going to change the plugs soon and wondering if it's worth changing the wires too. I feel like I'm half-a**in' the job by changing only the plugs and not giving the engine it's maximum spark. But at the same time, I don't want to change something I don't really have too. What do you guys think?

Also, what are great plugs to use?
Thanks all!

 

i would, only because it's hard to get to, u might as well do it.

 

Inspect your plug wires to see if there is any cracks or damages to it. More than likely you will not need to change it since our cars are coil on plugs which requires that you need to purchase the wires from lexus or toyota. Make sure you don't break the clips on the coils when replacing the spark plugs. As far as plugs go, what is the primary use of your car? If it's mainly for street driving, then I'd stay with the factory toyota denso platinum or the NGK iridium IX.
