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.

        Nothing i wrote my comments above a statement above
        Size: XX-Large, Color: Navy Blue
        This item was not good quality, so I decided to not not use. It came pretty much wrinkled and folded in some package. And once again, it was not good quality was all wrinkled up you had to Send it to the cleaners to straighten it out and it didn't fit very well. It just wasn't there very good quality, kind of heavy, so so\n I'm not sure if I'll return it or just donate it to the local church. Thank you art cruz

        Fantastic product... fantastic fit !
        Size: X-Large, Color: Black
        First off, China got this product from their country to ours, then to my hometown.... faster than my own post office could get it across town after much bickering. So... thank you to the Chinese. Complaints about America being better... then start doing better. Secondly the coat was far superior than I even suspected. It fit well and I cannot wait until cooler weather to break it out ! Again... thank you China ! Highly recommend this product.

        I Wore These So Much I Almost Forgot I Owned Other Pants
        Size: 48W x 32L, Color: Dark Rinse
        I've been on a lifelong quest for the perfect pair of everyday jeans—durable enough for yard work, comfortable enough for a long car ride, and presentable enough to run errands without looking like I've given up on life. Having worn everything from high-end designer denim to discount store brands, I approached these Wrangler Authentics with a healthy dose of skepticism, especially given the price. I'm now a convert. I've had these jeans for about four months, and they've been my go-to for everything from building a shed to grabbing coffee. The relaxed fit is exactly what it promises: not baggy, but with plenty of room where it counts. The cotton fabric feels sturdy but not stiff, and they've held up to numerous washes without any noticeable pilling or significant color fade. They’re a workhorse of a garment, and for the price I paid, the value is simply unbeatable. I got a quality product that feels like it should cost twice as much. Pros: Exceptional Value: The quality far exceeds the price point. Comfortable & Relaxed Fit: Provides ample room for movement without looking sloppy. Durable Fabric: Holds up well to physical activity and repeated washing. Classic Style: A timeless look that works for almost any casual occasion. Cons: So Comfortable They're Addictive: They may cause you to neglect all other pairs of pants in your closet.
