2014-2018 Mazda3 & 2013-2017 Mazda6 Cold Air Box

I am disappointed.



The plastic does not match other products under the hood. Im from Europe,and here the police is very strict about aftermarket parts that dont have TÜF certificate. So it would be better if the plastics matched with original mazda plastics. Also CS logo on the lid, i would rather have a removable sticker.If you are not from Europe you dont have to worry about that.



Another disappointing thing is the lid. It doesnt have a seal.I had to buy sillicone to seal it. Why screws for the lid? It would be easyer if it just snaps in place,like oem box.Would look better too.



At low rpm and full throttle, box vibrates very loudly. Not a nice sound. Fixed it by sealing the lid and reinforcing the inside of the box.



The biggest problem is water. When is raining, alot of water is pulled in, rain and muddy water. Still figuring out how to fix this.



I hope this comment will serve to improve products in the future.

Great product nearly matches stock plastics, looks good under the hood. The biggest downfall is the rattling and added vibrations. Since this will not be something you open up and check daily I would recommend that you use red locktite on the lid screws in order to keep the lid tightly sealed maybe even silicone the lid shut it will dampen the vibrations significantly I did this after a few days do to vibrations car feels almost stock. Before I used lock tight the vibrations got worse and effected the drive greatly and I nearly lost a screw do to harsh vibrations ( this is why I recommend red locktite) Still needs to be tuned though the intake does add a little more pull up top but definitely needs a tune to maximize efficiency. Last but not least it does make the cars induction note much more pronounced so if you're not a fan of that I'd suggest going with a dry panel filter and calling it a day. The OEM intake has a strange design that runs a very long length in order to quiet induction sound. I enjoy the sound but it may not be for others.

My tuner recommended another brand of SRI, but the part throttle pumping noise was just too much for my older ears. CorkSport's FAQ said their Cold Air Box would accommodate my SRI, order was placed immediately. Install was a breeze, noise is now reduced to a less obtrusive level of NVH.

Fit and finish are good, looks really good there in the engine bay. Money well spent, I didn't have to cobble something together and hope it was effective.

I have had the Cool Air Box installed for just over a week. I am very happy with how they incorporated the Mazda designed airflow source. I can feel that there is less bog down and heat swap when driving.



The engineering is good. My only complaint is that there is significant amount of vibration at times. Definitely a plus though performance wise.
