I have a custom cold air intake installed on my teg and I was wondering if it being much bigger in diameter compared to an AEM cold air could have a negative effect on my car’s performance?
Theoretically,
You’ll suffer or gain nothing at the lower rpm, but possibly gain a lot at higher RPM compared to a smaller diameter intake pipe.

isnt it “the more air the better” … well at least the more cold air the better …
how much bigger is the piping? i suppose if it’s not all that much bigger, you shouldn’t have much to worry about. the intake will only allow as much air into the engine as it can squish into its cylinders, but there is a “velocity” thing going on.
though it’s not anything to really trouble yourself over, think of water going through a hose. if your hose is really large and there is very low pressure of water being let out the hose, it will only drip out. contrarily, if the hose is too small and the water pressure is high, there is a bottleneck that’s created and impedes flow. hope this helps out a little.
It does make sense now that I think of it. Thanks!
But it takes much more pressure to push the water quickly through the hose if it’s large. Cold air isn’t the only factor in intakes. It’s Cold/Quantity and Velocity. So if you have a huge pipe it’s obviously not flowing as fast. I havn’t discovered a happy medium between big and small. I’m still experimenting with different diameter tubing.

This is true during normal driving conditions. Bigger pipes are more efficient at WOT since the engine now has the suction power to ingest whatever it can. That’s where smaller piping loses its advantage.
Think of two straws: 1 thin, 1 twice as big. Imagine yourself being the engine and you have to suck water through the straws. If you’re dying of thirst (WOT), which straw would you rather use?

The skinny one cause if I drink too fast I’ll get a brain freeze.
:lol:
i wonder if you can tune it for more lower end torque and what would be optimal… or if you can make an easy interchangeable system
