K&N 57i Generation II Induction Kits are built primarily for European vehicles. They come with K&N's Million Mile Limited Warranty™. These intake kits use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter alone. The weakest link in the airflow "chain" robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

I got my 2014 Mazda 3 S 2.5 in April and immediately replaced the paper filter with a K&N filter. However I had been thinking of replacing the intake with a High Performance Intake unit. I checked with the Service Manager at my dealer to see if there would be any warranty issues. He said that it would not impact any warranty coverage (although he suggested that I could replace the K&N unit with the original air intake if there was a factory recall on the fuel system). I found this kit really easy to install. The photo instructions were well detailed and easy to follow. I was amazed at the length of the original factory unit. From the 5 inch slot opening it takes a 90 degree turn, goes down 20 inches into the fenderwell, does a 180 and goes back up another 20 inches to the bottom of the airbox. The K&N unit occupies the same space as the factory airbox and is a short 12 inch run to the engine. As I said it was an easy, follow the step/photo installation. The use of the factory air sensor meant there was no recalibration or special tuning required. I just started the engine, checked all of the fittings and clamps to be sure there was no leakage, shut the hood, took a short test drive and it was good to go.
You can easily feel the performance increase, especially with the 2.5 liter engine's automatic in sport mode. My brother, who used to sell Mazdas, drove the car before the upgrade and after. He agreed that the performance increase was very noticeable. Plus we both found the very deep intake growl (most noticeable in the Sport mode) to be a blast. It can be intrusive, but isn't anywhere as noticeable when your driving in the normal mode, so this isn't an issue for me.
I stopped at my dealer and 3 of the salesmen wanted to see and hear the KN Typhoon. They all loved it and they plan to talk to the Parts Manager about making the kit something that he offers rather than the current I can get one for you which is what he told me when I asked about K&N products.
I wanted the kit right away so I checked availability at the O'Reilly Auto store's website (very big in Minnesota). They listed a K&N Typhoon kit. However when I checked with the K&N website the part number they had listed was shown by K&N as for the 2004-2012 Toyota Corolla. So if you want to get a Typhoon kit through your local dealer, be sure to go to the K&N site first to be sure that you get the correct part number.
All in all I can highly recommend both the K&N Typhoon Performance kit and ordering directly from K&N. Both exceeded my expectations.

I've used K&N filters on all my vehicles for the patst 15 years. I have never had a problem or defect with any of the ones I used. Custom 2001 for Lightning, 83 Ford Ranger 306 385 HP, 2001 Toyota Corolla Power Adders. I don't think there is anohter brand out there that meets up to the spec's and performance of K&N filters, I'm sold and will have have one on the next build I do.

I bought this for my 1999 Toyota Corolla. It was a perfect fit and made my car run better and quieter than it has since I bought it. It's ready to go out of the box and was super easy.
