In studying the 2012-17 Fiat 500 1.4L Turbo (including Abarth) and 2013-16 Dart 1.4L, we found the stock throttle body necked down a decent amount in the throttle body bore. When the inner bore necks down, it restricts incoming air and makes the car less throttle responsive and fun. We also found that the throttle body was assembled with much larger than needed screws with a large button head and threading that went past the butterfly plate.
So, the tapering of the throttle body combined with the oversize screws impeded airflow, and creates a less than optimal enthusiast driving experience!
That lead to us porting out a TB, installing a larger butterfly plate, using flush screws versus the factory huge screws. We opened up the inner bore nicely and improved air flow into the intake manifold quite a bit.
By doing this, we were able to gain a solid 6 hp at the wheels, and make our Dart 1.4L Turbo even more fun to drive as the throttle was more responsive!
Porting out a throttle body like the Dart's is not an easy task! The Fiat/Dart 1.4L uses a drive by wire throttle body which means that the throttle body is driven by a motor. So, in order to bore out the throttle body we need to disassemble the drive by wire throttle body, remove the motor and gearing, remove the throttle plate and screws, bore it out, install a new throttle plate, and reassemble.
Now, we begin with BRAND new MOPAR tb's that we port, that you buy outright. This means you get a brand new drive by wire throttle body with motor. You can reuse your rubber intake manifold gasket.
This throttle body works great with both automatic and manual transmissions!
- Improves throttle response, makes for more fun driving! You can daily drive your car, even in rush hour traffic with no problems!
- Horsepower and torque gain across the board!
- NO check engine lights, no idle problems, no issues at all!
After you receive and install the throttle body, do the throttle relearn procedure:1. Turn off all accessories
2. Insert key and turn to "ON" (Not Start)
3. Wait for the "DING" to depress throttle to the floor fully until check engine light flashes
4. Hold until CEL stops flashing
5. Turn key to "OFF"
6. Release throttle
7. Wait 2 minutes before start-up
Fits the 2012-17 Fiat 500 1.4L Turbo, 2013-16 Dart 1.4L and 2015-2018 Renegade 1.4L.
