AVOTurboworld`s 5-ply Silicone Inlet MAF tube is much larger than stock, especially at the bend. The interior of the OEM inlet is 70mm (and gets reduced further at the accordian section), while the AVO measures up to 80mm. This translates to over 10% better air flow, especially as it removes the accordian section. The 5-ply reinforcment ensures it will not collapse, even under the harshest conditions!
On AVO's flowbench the AVO MAF tube recorded a sizable increase of 8 CFM over the factory MAF tube.
