K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Series Intakes are not legal for use in California and other US States adopting California emission standards.

A mind bender.
Format: Paperback
Robert Monroe's story is such a remarkable one that for me it took a few years of pondering and re-reading various accounts of his "journeys" to come to grips with it as a legitimate reality. Since the early 1960's, Monroe carefully logged many hundreds or thousands of out of body experiences and over the years mastered exit techniques and went on to teach them to many students at his institute in Virginia. Far Journeys is a wild ride and was at times difficult to follow due to the many terms RM coined to describe the completely unknown entities and experiences that became routine for him. Once you get accustomed to the vocabulary, the narrative becomes more intelligible. The book is really something of a travelogue to non-physical reality. He is not stopping along the way to explain things to us readers, but leaving the experiences to speak for themselves. In the end, one is left to grapple with the implications of all he is laying out. Is he just completely insane? I don't think that is the case. Monroe was, in my view, a true modern mystic, born into a highly academic and rational Western world. He brought all of his pragmatism and mechanistic views on the world to bear as he wrestled with his remarkable gifts. He is really the heir to Edgar Casey, and in turn any number of mystics from antiquity.

Well written, entertaining - whether this stuff is true or not depends on your opinion.
Format: Paperback
I loved Monroe's first book. *This* book is entertaining, although annoying at times trying to figure out who's talking. I'm silent on whether I believe Monroe's fantastic stories. But if you're okay with that risk, I'd recommend this for both entertainment & perhaps to help unleash some creativity in your self.

Changed forever
Format: Kindle
We become so mired in our subjective “reality”. I find it truly beneficial to have a different, perhaps more objective perspective. I hope this enables me to make necessary changes to my journey before its conclusion.
