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 aluminum 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 2013-2018 Focus ST and the new 2016-2018 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.This Part Fits:

Classic look, great feel and great price.
Color: Black, Size: X-Large
Super comfy and casual, but classy enough that it can be worn out. I find this shirt extremely comfortable, it is a classic look and is very flattering. I wear a size 14 and the XL is loose but not baggy. It washes well, does not wrinkle if I get it out of the dryer and folded in appropriate time, and the material is a good weight for the cost of the shirt. I would likely buy again as this is a great summer staple.

Runs true to size and well made!
Color: Black, Size: Medium
I am very pleased with the size and cut of this top. I hesitated on sizing (at 5'1" and 105 lb) because I like a looser fit and am sometimes given different size recommendations. Many times the tops are too large and must be altered or simply passed on to thrift stores. This shirt in a medium is perfect in its fit, flows nicely. The neckline is not too low, but more like a shirt with a couple of top buttons unbuttoned- no gap. The sleeve length is good for me as my shoulders are a bit narrow. (I checked and no way to remove the stitches that hold the sleeve into a cuff. They are deeply embedded into this soft opaque fabric that has some stretch. (Even with the best of seam rippers and sharp eyesight!)I think the rolled cuff is cute! Top drapes well and is a great length for jeans or shorts- dressy casual wear, with its perfect fabric thickness. I really like the black color. I would not wear it with leggings because of the length, but jeggings are great with it. The little contrasting buttons are a nice touch. Great value buy.
