GHETTO custom intake, motor runs but not very good need help! - Toyota Yaris Forums

The MAF needs to be inside of a 2.25 inch pipe. The air velocity inside of a 3" pipe doesn't move past the MAF fast enough. So you're starving your engine for fuel. Put it all back to stock, or find a 2.25" MAF adapter or risk doing engine damage from running way too lean.
