Add some reliability and engine bay styling to your Focus RS/ST with the Mishimoto RS/ST expansion tank. This tank features internal baffles to prevent coolant starvation from overflow ports on the engine. Also, during high speed cornering, braking, and acceleration, the internal baffles reduce coolant sloshing. The engineers at Mishimoto have included a sight tube to allow for proper observation of hot and cold coolant levels, making engine maintenance much easier.

Eventually, you’ll have to consider the health of your plastic expansion tank. Plastic is prone to failure after years of constant temperature variations. The Mishimoto tank is constructed from durable, TIG-welded aluminium for optimal durability and longevity. It reuses the stock expansion tank cap and includes an overflow nipple on the fill neck for adding an additional coolant tank so your Focus RS stays NHRA legal. All areas of concern are covered with this upgrade.

It’s worth noting the Focus’s stock tank is an engine bay eye sore, whereas the Mishimoto tank comes in three different variants to help with aesthetic customization: black, wrinkle red, or Wrinkle Nitrous Blue. Each of these options works with both the 2012+ Focus ST and the new 2015+ Focus RS. For convenience, you can install your new coolant tank upgrade in under one hour as it was engineered with perfect fitment in mind. Like all our Focus RS parts, this expansion tank also includes the Mishimoto Lifetime Warranty.

        Engaging and Educational! Perfect for Little Astronomers! 🌟
        Format: Board book
        "8 Little Planets" is an absolute delight for young readers and their parents alike! As a parent of a toddler who is just starting to explore the wonders of space, I found this book to be a fantastic introduction to the solar system. The colorful illustrations are vibrant and captivating, immediately drawing in little ones' attention. The rhyming text is fun and easy to read aloud, making it a joy to share this book during storytime. What I love most about "8 Little Planets" is how it manages to make learning about the planets so engaging. Each planet is given its moment to shine with a little story that is both informative and age-appropriate. The book also subtly incorporates the latest astronomical knowledge, like the reclassification of Pluto, which is a great touch. It's clear that this book was created with care and attention to detail, and it's become a favorite in our home. Whether you're raising a future astronaut or just looking for a fun way to introduce your child to science, "8 Little Planets" is a stellar choice!

        Format: Board book
        My niece loved this book. As did I! I always found outer space fascinating, but have forgotten many facts from my youth. When I ordered it, read it through and was very happy about all the information packed I. Such a fun book. There is even an honorary mention of Pluto. Vibrant, fun, factual, EXCELLENT! she got a astronaut costume also, so now she’s got all the tools for her imaginary space travel.

        Amazon should know how to deliver books without damaging.
        Format: Board book, Format: Board book
        This is a fantastic book and the back has fun facts, plus a dedication the minor planet Pluto that was not included. If you are Gen-x you know that acknowledging Pluto on the back just warms yor heart. Most of the science info is on the back cover. The board book focuses on naming the planets and the artistry. I think this is great and the extra facts on the back are better for older kids who might want to pretend they are too big for baby books. This is a really beautiful book, but there was damage. The lip is all suffered up and marred (2nd picture) and where you open the book (1st picture) there is already a wear crease. I blame the defects on Amazon, but a cellophane wrap might have helped prevent the damage
