The COBB 3-Port Boost Solenoid is an excellent upgrade for modern turbocharged vehicles, enabling precise boost control in a tidy package that is easy to install and tune. Our BCS will eliminate boost fluctuations inherent in OEM boost control systems, providing the necessary stable and repeatable boost control required for accurate tuning and consistent performance. The COBB BCS is equally capable of providing stable boost control at stock boost levels as well as extremely high boost levels associated with big-power builds, with an operating range of up to 120psi. The COBB Tuning 3-Port BCS features 1/8" low-profile barb fittings to keep the unit compact, and are nickel coated for corrosion resistance. Optional 1/4" nickel plated fittings are also available separately. Viton spools and seals are used throughout for long life and lubricated with Dow Corning silicone grease. The manual override port is sealed with an O-ring, the wiring harness is sealed to the casing using a waterproof grommet and the solenoid wires are ultrasonically welded to the coil, making the device waterproof and safe to wash.

Great summer workbook
Format: Paperback
This book is a great tool to use over summer break to prevent loss of learning. I have been using this book with my 2nd grader for a few weeks and he enjoys the short lessons. I would prefer the lessons have a few more questions to cover each lesson.

Great way to support summer learning!
Format: Paperback
I absolutely love the Summer Bridge Activities: Bridging Grades 3–4! This workbook is a fantastic way to keep kids engaged and learning over the summer break. The activities are well-designed, fun, and educational, providing the perfect balance between reinforcing what they’ve already learned and getting them excited for the next school year. The layout is visually appealing, with colorful pages and interactive exercises that make learning feel like play.
What I appreciate most is how it covers key subjects like math, reading, writing, and critical thinking skills in bite-sized chunks that kids can easily manage. My child enjoyed doing a little bit each day, and I noticed significant improvement in their confidence as they completed each activity. It's great that this workbook also includes helpful tips for parents to guide their kids through the exercises.
Overall, this is a must-have resource for parents looking to keep their children sharp and engaged during the summer while still having fun. Highly recommend!
