The 2012+ Fiat 500 Turbo/Abarth is a great car, and it's a lot of fun to drive. But, its still a mass produced car, and Fiat sometimes leaves some room for improvement in some of the parts design.
The factory plastic duct that goes in between the airbox on top of the motor to the turbo is one of the pieces that we think could be better designed. The inlet and outlets are circular, but the center section is square. So, the air flowing towards the turbo goes from circular to square and back to square. Also, most importantly, there are huge casting ridges in the tube that impede and slow down air flow. (Please see stock air tube cut in half to show casting ridges below).
What this does, is cause unnecessary air flow restriction. This makes it so the turbo spools up slower, and lessens power.
So, we designed an aluminum duct with very smooth bends, and designed the transition to the turbo rubber elbow to be super smooth. This allows air to flow easier into the turbo, making for a faster spool up and more fun driving!
To further illustrate the turbulence caused by the casting ridges in the intake pipe, please see our two photos below in which we used water to show you the flow characteristics of the stock pipe vs mpx. In the stock piping, you'll see that the water hits the casting ridge, slows down and jets upwards. Then, by the time the water exits it slows down and nosedives down.
The MPx piping on the other hand, has a very nice smooth flow and transition. You see very little upset of the flow of the water, and the velocity of water as it exits is nice. You can see a difference in the speed of water exiting! (Please note, we did not change the water flow, or angles between the two pipes). See photo below of MPx piping cut in half to illustrate flow.
So, if you want increased power, faster spool up of your turbo on your 1.4 Turbo 2012+ Fiat 500 Abarth and turbo model, get one of these MPx after airbox intake pipes today!
Installation is simple, undo the two factory clamps that hold the factory airbox piping to the rubber hoses, disconnect the two breather hoses and then replace with the MPx piping. Then, tighten the clamps and you are good to go!
