Plugs & wires

Recommended Posts

Looking for the best plugs and wires for my 2005 GT Wagon. Currently all it's all stock except for a mild tune peaking 16lbs of boost. What is the consensus for which plugs and wires would be best for my application? Any help/direction will be greatly appreciated. Thanks, Rob

So after some research I see that most have you have used one of these 1Step colder plugs: NGKSILFR7A or the NGKLFR7AIX

Which one is better to support up to 20lbs of boost with supporting mods? Any help would be really appreciated.

I run colder plugs because they were cheaper and less prone to knock.


My wagon is my DD all year.
