Most air filters on the market are a compromise. Many high-performance filters deliver better airflow, but sacrifice filtering ability and engine protection in the process. OEM filters, which are usually made of paper, filter adequately but at the expense of airflow. And airflow decreases as these air filters become dirty. Not so the K&N air filter. K&N air filters increase airflow without decreasing filtration ability, and the increased airflow remains consistent throughout the filter's service interval. The secret is in the K&N filter's construction.

K&N's initial goal was to develop a filter that would deliver increased airflow during dirty, dusty off-road racing conditions. Increased airflow improves the efficiency of the combustion process, increasing horsepower and torque. But just increasing airflow without ensuring adequate filtration under those conditions would result in a ruined engine. K&N's solution was a filter design consisting of 4 to 6 layers of cotton gauze sandwiched between two aluminum wire screens. The cotton is then treated with a specially formulated grade of oil that causes tackiness throughout the cotton’s microscopic strands. The resulting K&N filter not only delivers increased airflow while trapping dirt particles that could harm your engine, that level of airflow is maintained even as the filter gets dirty. The layers of oiled cotton fibers in the K&N filter trap dirt particles that are smaller than the holes in the filter media. The thickness of the layers also allows the K&N filter to trap dirt and dust on many levels, trapping more dirt without decreasing airflow. Contrast this with a paper filter that only traps dirt on its surface; as the surface area becomes clogged, the airflow rate goes down.

Each K&N air filter is custom designed to fit into your existing factory air box. The K&N filter is economical because it's the last air filter you'll have to buy for your car. It can be washed and reused many times, and since you can usually drive up to 50,000 miles between servicing, you won't have to clean it very often. And every K&N filter is backed by K&N's Million Mile Limited Warranty. By the way, check the CARiD reviews and read what the customers think of K&N porducts.

Good book, mediocre edition
Format: Paperback
This review pertains to the quality of this edition's editing and construction, rather than the content of the book itself. Rest assured that the text itself remains a valuable piece of introductory theory. The book is fairly well constructed, with paper and a binding that is sturdy enough for general use. However, my copy had several manufacturing errors including folded over pages being stuck into the binding. In addition, there are several misspelled words throughout the text and some obvious typos (missing letters, incorrect capitalization and punctuation) that did not majorly impact the readability of the text, but were, nevertheless, annoying. Considering the low price of this edition the manufacturing errors are hardly a big deal, but I would have preferred the text itself to have been treated with more care and respect while being prepared for printing.

thoughts on Xi Jinping
Format: Kindle
This book was highly organized and very easy to comprehend. I have formed a much better understanding of Xi Jinping and where he is taking China. Although I feel he has been thoughtful and successful in some areas such as improving China economically, I don’t feel his autocratic approach will succeed in the long run when more Chinese people will demand to be heard. Just as Mao thought didn’t outlast Mao, Xi thought will not outlast Xi.

The Book I Meant to Write
Format: Kindle
While doing my master’s degree in international relations, I completed a master’s thesis on Xi Jinping Thought (which, like the authors, I shortened to Xi Thought). I considered writing a book on the subject since there wasn’t a lot in English, but I no longer feel the need. This book fills every gap that was present. Well written and informative, it is the quintessential English source in Xi Thought. The authors put Xi’s political thought in a consultative Leninist paradigm and define that context clearly. Each chapter elucidates a little more and puts Xi thought front and center in China’s current transformation. I consider it a must read.

Great read and most importantly very topical
Format: Audiobook
The writers use published work of Xi and Chinese government official statements to describe the true nature of this most important Chinese leader who will have profound impact on the total world.Like it or not it is essential for all of us to really what he is preparing his nation for the vision he has.Americans are naive and totally ignorant.

Pure anti-China propaganda
Format: Audiobook
From the first few sentences they get the name of the ruling party of China wrong and it only gets worse from there. This is purely a work of western propaganda and in no way academic or objective. I've studied China for many years. You will find nothing of value from this book. All of their achievements are minimized or disregarded entirely. You will also notice that very little data is presented if any at all.
