ive been tracking that for awhile. i think since last month i saw it on the site but no pricing.
Sorry if this is a dumb question, but installing a CAI w/o a tune, wouldn't that make the car run lean?Ask and you shall receive! Data, dyno numbers and sound clips from our Cobra Cold Air Intake system is finally here! We will be offer Si and Non-Si specific systems!
2017 Honda Civic Si w/ Stock ECU Mapping (Not Tuned Whatsoever)
What's important to note here is that these numbers are in comparison to our previous dyno session where the car had the same exact modifications except with our Stage 1 intake system instead of our cold air so we didn't have to put everything back to stock.
- PRL Motorsports Catted Downpipe / Front - Pipe Combo
- PRL Motorsports Prototype Intercooler
- PRL Motorsports Prototype Cobra Cold Air Intake System (Street MAF Housing)
We made sure all conditions were identical for testing (ie 55% knock control value, ~180 degree coolant temps, similar ambient temps, etc) and this is what we came up with.
~5 horsepower and torque gains throughout almost the entire powerband in comparison to our Stage 1 intake system. This means 9 - 14 horsepower and torque gains throughout the entire powerband over the factory intake. No these aren't crazy marketing ploy gains, these are honest, tried and true gains that every person can expect to see by simply installing this intake system on his or her 1.5L Turbo Civic without a tune. It's important to note that the car was making 1-2 less pounds of boost throughout the midrange, hence why torque gains were minimal down low during peak torque. These cars are very sensitive with knock control and how it controls timing/boost.
We found the MAF curve to be extremely stable, identical in response to the factory intake. This will be our first cold air intake system ever to not require any tuning whatsoever. Customers can expect greater gains once the boost is turned up and components are pushed to their max. Once we find the limit of the Street MAF we will test our Race MAF
Here is a comparing our 10th Gen Si when it was stock to everything that has been modified now. Very impressive results for no tuning whatsoever! Next comes the fun part... Tuning with @KTuner!
Sorry if I've missed this if answered before, but would I be able to run the CAI in SRI format?Ask and you shall receive! Data, dyno numbers and sound clips from our Cobra Cold Air Intake system is finally here! We will be offer Si and Non-Si specific systems!

In most cases this is somewhat true, or at least the fact fuel trims are thrown off due to altered MAF sensor readings. However, we 3D scanned the factory MAF housing with our FARO Arm to replicate and manipulate these dimensions. In doing so, our billet aluminum Street MAF housing is designed identical to the factory intake's MAF housing in an effort to provide stock-like driveability and safety. In testing, datalogs have showed that our Street MAF housing lives up to the expectations, meaning no tuning required! Long Term and Short Term Fuel Trims showed to be as stable and even smoother at times than the factory intake system.
At this time it does not.
Oh, so it has to do with the MAF housing that results in not needing a tune, and has nothing to do with the increase in air volume? I never installed a CAI before because of the very reason of messing w/ the air fuel ratio, so my questions and concerns maybe a bit elementary.
You are correct that it CAN change a cars A/F but its usually so small that it's not needed to worry about in any way. A MAF size change, and possibly a relocation CAN require a tune. I have seen a 3rd Gen Taurus SHO loose 12WHP on a dyno just because the stock MAF was put in upside down by accident. Once the MAF was rotated back around everything was just fine again.
I am too lazy to rip off my bumper to install a cai. Guess I'll either get a mishi, injen or wait for prl to develop a sri for the 1.5t
Prl knows this platform makes no power with a short ram intake, so I don't think they plan on making one, they have the stage 1 filter tube combo or the upcoming cobra stage 2 cold air intake. Short ram intakes are for the kiddos, gotta have that turbo whistle.
That would be mostly correct. Our Street MAF housing is sized/placed as close to stock as possible so that the voltage reading do not throw off AFRs. There is a nice little writeup on page 1 with how MAF sensors, intakes and air volume work.
MAF systems can be VERY finnicky. We have seen strange behavior such as driveability blips and AFR spikes/dips due to changed MAF housing size and placement.
This can be installed without taking off the bumper.
We have tossed around the idea of doing a short ram, but see no reason for doing so with the results of our Stage 1 and CAI systems. If you bang-for-the-buck gains, go with our Stage 1. If you want all-out performance and a sweet "whoooosh" sound, we have our CAI.Prl knows this platform makes no power with a short ram intake, so I don't think they plan on making one, they have the stage 1 filter tube combo or the upcoming cobra stage 2 cold air intake.

Awesome!
