I have Denso Iridium spark plugs at home. Do I only need a gapper to install these? Is there a lot more to it? Also, I really want to get performance spark plug wires. What do you guys suggest for our beautiful cars?

 

don't know much about spark plug wires, but I know they would not increase performance at all on our cars. Whatever the system is called. I'm sure Radams knows

All you need to install these is take one out put one in.

 

Plug wires are gonna be tough because our car is distributorless, coil-on spark plug wires. I don't recall that anyone makes performance wires for that.

I do believe the plugs are already gapped properly. I don't believe I had to do it when I put mine in.

 

I just need a confirmation. They're supposed to last like 30k miles on our cars right?
