The AEM 21-642P Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicles restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Mazda Mazdaspeed3 models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is relocated to the driver-side wheel well which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable chrome-like finish. This air intake system was developed to accommodate the engines factory emissions control devices including the mass air flow sensor and breather hoses. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is backed by AEMs Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

    Great Book for Project-Based Learning
    Format: Paperback
    As a Unity Instructor I can say the book is really amazing I was expecting that I'd face a basic book, but instead, the book is very complete, even having AR and VR chapters totally adapted to the new version of Unity, which makes it one of the best books to master Unity (if not the best).

    Content seems good, but support files/code are insufficient, and the code seems illogical in places
    Format: Paperback
    This books starts out great and the content/approach seems solid. But I ran into several issues when the coding portions were introduced, notably when it came to collisions and destroying enemy game objects. There's scripting to set up a bullet behavior, but from the outset the behavior is buggy, and when the "explosion" behavior is introduced, there's no coding to actually destroy the object you're introducing the explosion behavior to. On top of that, the explosion behavior is tied to the playerObj's "onDeath" function, so ... I'm not sure how any of that ties into destroying an enemy game object. This is about 150 pages in. The go-to method in these cases is, of course, to reference the support files, but these files only include the code and the book images. What's really needed is the Unity project files to ensure the code is being implemented in the components of the game objects and seeing the core structure there. With only the scripts, you can only check your scripts against those, but you can't be sure you're utilizing them correctly and tying it all together in Unity. Granted, I'm still learning the platform, but things like where you're expected to fire a bullet that has no "destroy gameObject" function into an enemy gameObject that also has no such behavior ... and the behavior is tied to the player? There's definitely something amiss. All the while you're dealing with "soft locks" in the test gameplay that could have been immediately addressed, but aren't. And you can't really move forward with such core inconsistencies in place because you fear the problems would just compound from there.
