NTK is the world's largest supplier and manufacturer of OEM oxygen sensors. Oxygen sensors play a critical role as part of the vehicle's on-board diagnostic system in maintaining optimal engine performance, maximizing fuel efficiency and reducing harmful emissions. While conventional switching oxygen sensors only switch rich or lean, wideband oxygen (or Air-Fuel Ratio) sensors produce a linear output signal that allows the ECU determine exactly how rich or lean an engine is running and make continuous and precise adjustments of the air-fuel mixture to stay closest to stoichiometric, providing the best possible combustion and fewest emissions. A ceramics company at our core, NTK uses state-of-the art technology enabling complete control of the ceramics used in our wideband oxygen sensors from raw material to finished product. Trust The Sensor Specialist for full-line market support and OE application technology.

Good Stuff!
Format: Paperback
Very good material for anyone considering marriage and even couples that are already married. However, it would be best to study this book prior to being married. Dr. Chapman has been providing quality material for many years. I started utilizing his material as an aid in counseling when it was on VHS. Like I said, he's been around. While this book is not an end all be all, it definitely has some great advice and insight within its pages. It works very well in conjunction with "The 5 love languages" and "The 5 languages of apology", also offered by Dr. Chapman. There are free online quizzes and other info that can also be utilized as mentioned in the book that will enrich everything else he discusses in the book. There are several applicable true to life stories inside that help you understand each point he is attempting to relay and makes for an easy read by keeping interest up. I also ordered the audio version and found it easier to listen to and take notes for self enrichment, as well as notes for guiding others into what I hope will be lasting marriages.

Great book!
Format: Paperback
Wonderful, helpful, insightful. Points out many of the key "sore spots" that can sour a marriage if left unmanaged, and how to address them. Very helpful, whether as a premarital counseling book, a book for the happily married couple, or even for the unhappily married couple willing to set their relationship right. Must read!

Good discussion book to eliminate conflict between couples
Format: Kindle
Use this book as a checklist of things you should discuss with your partner - especially if you're considering or are in a long-term relationship. It explains each topic, why it's a likely source of conflict, how to prevent the conflicts, and includes questions for discussion between partners. Understanding and discussing these topics may not feel romantic and fun, and some of the conversations may be challenging for couples who aren't accustomed to such discussions. Do it anyway though because it will eliminate future conflicts before the conflicts even begin and make your relationship run smoother, last longer, and be a source of relaxation and contentment for you both. I'm speaking from experience here. If you are new to the study of this topic, this book will be extremely valuable for you. If you've already studied interpersonal relationships, preemptive conflict resolution, and collaborative negotiation tactics, it's still a great checklist of topics to discuss with your partner. I'm on this end of the spectrum, hence 4 of 5 stars because I'm familiar with the author's other work and this book didn't contain much new content. As a compact, all-in-one, relationship discussion guide though, it's great and worth reading and having on hand for future reference for new relationships or for when new conflicts crop up.
