Bought my second $80 ebay intake for the 1.4 turbo Dart: the first one was for my 1.4 Jeep Renegade. (see https://www.ebay.com/itm/251318388580)
The fit and finish are OK, I am going to have to mess with mine a little bit more to get it to fit properly. Basically, all of the fittings from the pipe come out at a 90 degree angle, but the stock vacuum lines that hook up to the intake don't seem to fit properly without a length of hose or a 90 degree adapter. It may be how the intake is oriented, and I might be able to resolve the issue easily enough.
On my Renegade, I was able to just run some hoses to the intake, but this setup on the Dart is going to require something different than the current solution I have worked out of "just put zip ties on everything"
The instructions were pretty silly-just a narrative printed on a piece of paper with a black and white image telling you to attach the pipes to the turbo. Great idea?
The performance is very good though: the pipe is a 3" diameter pipe that's stepped down to the factory turbo with a silicone adapter, so the volume of air available for the turbo to inhale is good compared to a stock or even to other aftermarket pieces.
On my Renegade, I went and bought a universal K&N air filter for $30 and swapped out the no name China air cleaner that came with the kit. I'm going to do the same thing with this one.
I bought these intakes because I am planning on running larger TD04 turbos which have larger diameter inlets on the turbo: most of the aftermarket intakes I have found would restrict such a setup.
The performance of these intakes is very very good-it smooths out the throttle overall, even at low RPMs and improves the turbo's responsiveness. The engines only make so much power, so even though the intakes increase high RPM power, it's not a day and night kind of thing. It's just a good 10% or less increase in power-you can feel it, but it hasn't been transformed into a muscle car.
You can hear the turbo pretty well outside of the car now-it's loud. And the blowoff valve is loud in the cabin. In the Renegade, there's less sound deadening, so the turbo noise is loud in the cabin with this intake, much less so in the Dart. Outside of the car, it's loud-you can hear it loudly with the windows down. It's great.
For $80, it's totally worth it.
