View Full Version : Other Air Intake Sounds


prophet51308-22-2011, 09:34 PMOkay this may be a big thread or it may have one simple answer. I was thinking about making a custom air intake as a small project for my Celica as I wait for the bigger projects to get started.

Back when I had my MR2 I ordered an intake off Ebay. Basically just gave the car a MUCH LOUDER sound.

I was wondering what all is behind the sound of an air intake, not trying to have a ricey sound, just something different. My MR2 sound was much too loud for my goals with my Celica.

Basically I guess I want to know if its all in the shape or size of the filter or if part of it is the passage from the filter to the engine? If it isn't just the filter, then what size piping does what? Does it depend on angles or curves? Or maybe its NOTHING like that at all. If it IS however the filter, what shaped filters do what, and does that vary by size?

My project would be simply for my auto 90 ST. But I'm completely open to all other set ups or input of course, especially if anybody else has made any custom air intakes for their cars. As always, I love pictures.

And if you'd like to show videos with sounds I'm sure that'd be the best comparison.

Jason.MZW2009-12-2011, 12:15 AMToyota puts resonators (the black boxes) in the rubber piping to quiet it down. A straight pipe without any resonators will be louder. You can also quiet down a custom open element intake with a smaller type of resonator (a size dependent box inline with the piping; dependent on how much sound you'd like to remove). You can tune that to your liking.
