Custom Intake Question

[speedminded]

I got a question for you guys.

I was planning to get a TRD intake for my 09' tC, but money has been short lately. With that said, I'm thinking about just making my own intake with those custom intake pipes they sell at Autozone, Pepboys, etc. I looked at my intake piping on my car, and i think i only need to replace the air box with a straight pipe for the filter and air sensor. If I do this, is there a chance of my motor running dangerously lean/rich? Is the stock rubber/plastic pipes okay to couple with the metal pipes? I've never had an intake system on my cars before, so I'm new to this stuff. Any help will be greatly appreciated

Also, I don't care about squeezing every little hp/tq out of this engine. Just want to get better flow and sound for my daily driver.

A cone filter on the end of an intake pipe in your engine bay is just a hot air intake. You won't see much if any gains from it, especially in summer weather...but it will make a cool noise. If you like the sound of sucking lol!

You aren't going to run too rich or too lean, the compute can compensate for slight adjustments in air.
