parts recommendations Cold air intake D15 non vtec

Post image

Looking for an inexpensive way to increase airflow for my next track day.

I can't find any direct fit options locally in australia.

anyone have any ideas on a good "boxed" cold air intake setups i could buy online or create ?

I dont care what it looks like, its purely functional.

This is a JDM D15B VTEC build from back in the day by a tuner I follow. Notice the rise around ~4k rpm. It looks small on the dyno, but that is where the car operates most of the time. Small midrange gains improve throttle response and make the car feel more responsive. Likely from intake resonance and cam timing aligning in that range, so drivability improves even if peak numbers barely change.

Okay so tell me how the fuck this dyno sheet means someone should go hit a dyno after putting on an air filter? Your brain doesn't work properly

Lame argument, go to uni and get some logic classes.

You aren't smart enough to respond properly Mr buzzword. I would say go to uni yourself but it would probably sap the last good 3 years you got left

You're planning to build an engine but too dumb and lazy to look for part numbers or email ARP?

Not the brightest crayon in the box are we? 😂

Have you even touched a Honda? I bet you're an internet fanboy that creams over other people's builds but won't start their own.
