We are very pleased to officially announce the DDMworks 1.4L intake. The intake has been tested and proven to show an improvement in horsepower and torque on the 1.4L turbo cars, while still keeping fuel trims inline with the stock readings.
The intake consists of a 304 stainless steel heatshield, an aluminum intake tube with CNC machined MAF adapter, K&N filter and all hardward necessary for install. We are selling the intake for $295 for everything plus shipping.
Some more description and answers about intake temps, restriction and power gains:
The stock intake does pull air from directly below the fender on the passenger side, which is cooler then the engine bay for sure and it does completely seal the top of the filter to make sure no air from the engine bay enters into the intake. That being said, the stock intake has a much higher restriction when compared to either our intake or the Injen intake, here is a graph showing the difference in restriction:
What that graph shows is that as you increase the flow of air going through the entire intake setup, the restriction increases with all intakes, although the restriction is much higher with the stock setup.
On a tunes 1.4L, this shows up on the dyno, and more power is made at the wheels :
The dark green is our test car with our intake installed and the dark purple line is the same car with the stock intake installed, resulting in a small but also repeatable change in power on the dyno.
As for the heat in the engine bay, of course while sitting in traffic the intake air temps are going to climb, but what we have measured with the heat shield in place, shows that intake temps are usually pretty close to ambient when the car is moving, and noticably cooler then without the heatshield. This is do to a couple of reasons. There is some air that still comes up through the stock intake tube and it is caught by the stainless heat shield we use and therefore goes into the filter. The other reason is that some of the air that comes into the engine bay between the hood and the front bumper is caught also by the heat shield and keeps the intake air temp low.
Lastly, the ECM is very picky about what you do with the intake on this car and most of the new cars out there are also very picky. The way that the ecm is picky though, involves monitoring the fuel trims. Fuel trims are used by the ECM to add or take away fuel so that the ECM hits its target air fuel ratio. Stock fuel trims fluctuate all of the time and are never "0", but instead generally will be less then 10% most of the time when short term and long term fuel trims are combined. So when developing an intake for this car it is very important to monitor the car with the stock intake to see what the fuel trims are, then when developing the intake for the car, make sure the the fuel trims with the new intake do not exceed what they were stock. As long as the fuel trims stay the same or less then stock, the ECM will be completely fine with the new intake and no retune will be necessary.
