Are there any Aftermarket spark plugs for the 4G? Some say that upgrading your oem spark plugs (ours are NGK) to a brand like Champion or E3 spark plugs that you can get 3-4 whp and increase fuel economy. Has anyone here replaced your oem spark plugs on previous cars? Any positive results?

NGK makes a VERY good plug. Stick with it.

Those Pulsefire sparkplugs or whatever they're called have my attention. I'd just like to not spend $25 per plug on them. I'm wondering if they do what they advertise though?

Maybe they should be packaged along with a quart of slick 50.

For the 3G, the OEM plugs provide the BEST performance even when compared to all of the more expensive "gimmicky" plugs.

I wouldn't be surprised if it was the same way for the 4G's.

I don't ever post in this sub-forum, nor do any reading. Decided to creep through for some reason, and I saw this thread.
4G owners should swing by the 3G performance sub-forum once in a while.
There's plenty of stuff there that apply to your cars as well.
Here's a small thread concerning Spark plugs.
