Hello guys,

I need your advice. I have installed in my MY2002 AP1 a js racing header, an exhaust 60rs js racing (stock cat) and an air duct with spoon filter drop-in. My question is if it

 

You'll be just fine with that setup. Earlier model years ran a bit rich from the factory. Even with more mods than that, you run virtually zero chance of damaging your motor due to a lean a/f ratio.

 

i wouldn't worry about basic NA mods like intake/exhaust/header. if you start getting into more advanced NA mods like camshafts/itbs/or high compression pistons would i worry about tuning. for now the lack of tuning will not hurt you but it will not allow your car to realize it's full potential without a standalone...

 

I really appreciate guys

 

If the A/F ratio becomes too lean will I have a CEL?
Will I have any problem in trackdays?

 

Your PCM will be notified about the extra air through various sensors (MAP, O2) and will compensate by adding fuel when necessary. Yes, there is a CEL for a lean condition, but you should not get one because of your new parts.

 

Thank you
