Hi Kim,

You will want to stay below 800 degrees or maybe 850 celcius at all times. The sweet spot is about 650 to 750. Anything close to 900 celcius is lean.

could new spark plugs help? if so what kind?

thanks

john

I have the same question on my setup. I am holding off on installing the Kinetix high flow cats until I get more info. I currently have

NISMO CAI
NISMO headers
Kinetix v4 plenum
NISMO exhaust

So far the car seems to run fine, but I haven't measured any ratios.

Should I expect the ECU to "learn" the correct ratio? I have a 2004.5 and no reflash is available yet. Any comments or suggestions?

Thanks.
