3D scanning has allowed us to replicate the factory MAF housing out of CNC'd billet aluminum for optimal driveability and performance. This cold air intake system is constructed of a 4" volume into the MAF Housing. Our kit is available with two MAF housing choices; a stock-sized Street MAF  and a 50% larger Race MAF housing. The larger volume of airflow reduces pumping loss as well as creates an unrestricted air path to feed the MAF housing with ambient temperature air.

Extensive testing shows that our attempt to replicate Honda's factory MAF housing worked extremely well; we couldn't be any happier! The beauty of this intake system is that customers can upgrade to our larger Race MAF housing to make more power in the future without having to buy a completely new intake system.

Notice how consistent and similar all of the LTFT graphs are. Each graph is within -4 LTFT.

All of the STFT graphs display identical curves and consistency.

Why use a PRL Motorsports air filter?

Our oiled filters are constructed from high quality, double layer cotton to increase the filtration surface by 10% - 15%. This causes air to move freely while maintaining superior filtration, trapping particles as small as 5 microns! The cotton filter is encased by coated steel mesh to ensure your PRL Motorsports air filter withstands the toughest of conditions!

Each filter is hand-molded using a flexible rubber base to ensure an airtight seal and absorb vibration. These filters do not use pressure-molding like other manufacturers, which can cause the rubber to seep into the filter element blocking airflow by up to 25%! Our air filters utilize a precision four-step process to virtually eliminate rubber seepage and maximize airflow!

Easy install, good sound.
Pedro Leal (Fort Washington, PA) 1/8/2019 11:14 AM
The hardest part of the install was figuring out the air-box is in two parts, so after unbolting the top half, just tug on it and it comes out. This will make it easier to take out the bottom box. PS the final bolt that holds it in is accessible from the bottom of the car without needing to lift it. Sound starts to be noticeable around 2800rpm and until you take your foot off the gas and you hear some great turbo sound. Getting a tiny more low end pull, but no improvement to the top end. I also think it's a little worse on fuel economy, maybe the car hasn't learned the ratio yet, but it's still worth buying and installing yourself.
Great sound and easy install

This is one of the easier intakes to install. The hardest part was getting the stock air box out. Once it's done and you're on the road the sound is very noticeable and slightly better midrange pull. Only thing I would add to the kit is install instructions for someone not mechanically inclined.

Bloody knuckles. That OEM air box was a whore to get out. PRL claims 9 to 14 hp. And I believe it to be on the higher end. Spinning the tires harder in 2nd gear than ever before. I had no idea I'd be this impressed. I would have ordered it a month ago when it was released. It looks bad ass. And it sounds awesome! I'm so happy.
