I did testing both ways, the results were slightly different. Mostly because of the way my enclosed dyno cell is designed. If I am testing multiple products in the same environment and there are changes between each product that is recorded and that is what you are seeing.
Here is an explanation of why we don't use an airbox, we have tested airbox systems on multiple different vehicles and hardly is it ever the best option.
The injen intake has a secondary inlet pipe that sits over the manifold, and that creates another source of heat in the engine bay. Again, we stuck with factory plastic piping as increased diameter showed no gains, and plastic has better thermal properties.
Air boxes do connect to "fresh air" source but has anyone taken apart the upper shrouding to see where the source of fresh air is coming from? It's not, that fresh air "channel" is basically sealed and only pulls in air from the edges by the headlight.
I highly recommend everyone to trim out the plastic to allow for true fresh air to get into the air ducting channel, I believe there are multiple DIY's on the forums here for this.
It does get a little warm at idle, but that is basically with any intake, I had the same results with the stock intake. The best thing about our intake is the recovery from heat soak. I can sit at idle in a parking lot on a 80° day and it will get up to 105° by the time I exit the parking lot and get onto the main road I am already within 5-7° of ambient temperature.
I already made a
large post on why our exhaust makes power, and downpipes do not. No other vendor or manufacture of products for our vehicles (Fiesta) do testing or data collection like I provide. If you don't believe the results, then I would suggest that you provide me data that proves otherwise. If I was in the business of making products to turn a profit I would of done the following:
1.) Skewed my results to show that our downpipe makes power, even though it doesn't. I only manufacturer a downpipe to support turbo upgrades that are already on the market and our turbo upgrade that will be released in the future.
2.) I would of used our Faro arm to probe the engine bay, and also 3D scanned the engine bay, then continued to make a 100% sealed 3D Printed airbox that would of jacked up the price. I have the facility and machines to accomdate the manufacturing of such a product but find it unnecessary.
3.) I would of put sheet metal end tanks on our intercooler instead of billet and sold it for the same price. We used billet because testing and data has proved it to be better, on our own vehicles and 3rd party testing. If I would of done sheet metal end tanks I would of sold it for the same price as the drive for our products is to out perform while still being price competitive. Billet end tanks was our choice to have the better fitting and performing product.
Sure, the common thing to do is to provide a better product and sell it for more because it is the better product. However as a consumer and manufacturer myself (ourselves) I find it much more appetizing to be above to afford a quality hand made product manufactured in the USA that has testing results, versus something made in Taiwan/China that only has biased reviews or half-assed testing

I have products already heading out of our facility and should be seeing reviews all over the forum. I'm sure you didn't miss the reviews of our exhaust posted all over
