27WON Honda Civic Intake Design Breakdown Round 2


A couple of weeks ago we dug into the creation and design of the 27WON Cold Air Intake System to show you how the unique design came to be, as well as some nice details about the design that may not be immediately caught by the eye.

Today I want to dig into the function and power of the 27WON Performance Intake. So Sit back, Grab a beer and enjoy!

OE vs 27WON Intake

Yup, we are going to start right off with the dynograph.

The above dynograph shows a very simple test; the drop-in performance improvement with the 27Won Intake.

This was tested on an otherwise 100% stock 2017 Civic Hatchback Sport 6MT.  As you would expect, the power gains come at and around peak power when the engine is flowing the most air and continues to have a small power increase to redline. 

Essentially the intake is doing what its supposed to do: breathe easier so you can get more air into the engine.  I’ll be honest, I would have expected more, but OE designs are getting more and more efficient as emission continue to push them, but let’s not dwell on that.

And let’s be real… we all know you don’t just throw an intake on the car and call it a day. You are going to go get a custom tune so you can really wake up your Turbo Civic.

This is where the 27WON Cold Air Intake really shines. 

It’s not just about the instant gratification upon install, its about the big picture: an intake system that is going to shine with further supporting modifications that will continue to help the engine breathe.  Let me show you why below. 

The 27WON Intake is a true Cold Air Intake without the worry of hydro locking your engine. This first data plot using Hondata FlashPro shows us the intake air temperature at the MAF sensor. Specifically the upper data plot shows the OE intake system; the lower data plot shows the 27WON CAI. 





Let’s breakdown this data to see what it’s really telling us. 

First our test conditions:

Each intake system was subject to an identical route and as close to the same time of day as possible. Traveling the same route for each intake helps reduce the chance for the route itself affecting the data; the run time, number of stops, speed driving and other numerous variables are nearly eliminated. 

The red X’s mark the data point recorded by the FlashPro and the blue line shows the average. Comparing the two data plots you will quickly see that the average IAT is much lower for the 27WON CAI, on average there is a 10 degree F difference! 

That’s the obvious difference, but there is also a more subtle trend that should be pointed out: 

The OE intake system has a nearly flat average; basically the speed of the vehicle does not affect the air temperature going into the engine.  Now look 27WON CAI… there is a very pronounced trend that correlates vehicle speed with IAT. 

So why is a delta of 10ºF a big deal? 

It’s not just about the quick power bump right install;

it’s the fact that the  27WON CAI design not only works, it will continue to help support your goals no matter what the other performance parts are on your car. 

We designed an intake so you can get the right parts the first time.


Thanks for tuning in with 27WON Performance!

I dare YOU to Redefine The Aftermarket
