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.

 

^ And some Nology Hotwires.

 

GO OEM THERE RATED FOR 100,005mi !!!!!!!!!!!!!!!!!!!!!!!!

 

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.

 

Better MPG=TSX, slower/smaller car

 

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.
