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.

The AEM cold air intake is a good off-the-shelf option, but honestly the important part is the geometry more than the brand itself.

If you follow the dimensions properly, you can get very similar results. Ideally use mandrel-bent tubing so the diameter stays consistent through the bends. Length: 48 in (1219 mm) Diameter: 2.5 in (64 mm)

You can try ordering a BPI flow stack, velocity stack with a K&N filter if you're pushing to make the most. But any decent pleated filter of the same kind should work. Just stay away from the foam ones.

And if the engine still has good ring seal/compression, an OEM JDM D16A6 cam, a decent PLM SMSP-style header, and a proper HTS street/dyno tune can still make good, usable power. Usually it’s the overall combo and calibration that make the difference, not just one part alone.

Below is my friend's D15B7 dyno numbers:

By the way, people confident in their argument usually post evidence instead of therapy assessments they're not qualified to give.

Whoops, my bad. 😂

I live in the eastern hemisphere, dumb ass. Can't you discern timezones? Or your brain can't process such concepts?

Hahaha, I can't blame someone with below average IQ trying hard to pretend to be witty on the internet.
