Got my S2000 tuned!

The difference in emissions between stock cat and hfc is minor (except when cold), whereas emissions difference between cat (stock or hfc) and tp is huuuuge.
Its highly irresponsible to run a tp when a few bucks more makes such a dramatic difference in emissions, and has minor impact on power level.

I don't believe the K&N intake is more restrictive (air flow considered alone) than the OEM airbox, but with heat soak and under hood temps considered the OEM airbox will be better overall in most conditions. I think both the K&N intake and the OEM airbox would both benefit from a dedicated airguide/snorkel.

Diy 3.5 intake with a velocity stack and aem dry filter. I did 232/165 on a mustang dyno.
A local who has a password jdm intake was only able to manage 222.
Were both basic bolt on intake header 70mm hf cat and exhaust.
After i went from kn intake to the 3.5 intake i was lean by 0.5 on afr from 4.5k to 8600
Also as a result i needed less timing to make more power indicating much more flow
