The Bilstein B6 Performance rear monotube is a yellow, gas-pressure damper that the manufacturer describes as a bolt-on upgrade for stock suspension, tuned firmer than OE. It is meant to sharpen control and grip on your existing springs, at the original ride height. All B6 shock absorbers and struts are tuned for each specific application, so this rear unit is calibrated for the Fiesta rather than a generic valve setting.
The case for a B6 over a stock replacement is the step up in feel. Owners on user forums who fitted OE-style B4 replacements say the car rode much like stock, and those who moved to B6s recommend them as the better upgrade for a firmer, more controlled rear end. Because the B6 is built to work with your factory springs, you get a noticeable change without paying for a spring kit or coilovers. Searchers looking for a 2011 Fiesta SE rear shock upgrade, a Fiesta 1.6L yellow monotube, or a B6 versus B4 rear shock comparison will find this part fits that need.
The manufacturer's fitment list covers the 2011 – 2019 Ford Fiesta, while the product title names the 2011–2016 SE 1.6L, so confirm year, trim, and drivetrain against your VIN before ordering. Installation is a rear-axle job that calls for a jack, stands, and access to the top mount behind the trunk liner. Owners on user forums say that top nut is the tricky part, and that you may need a thin or long-reach socket to reach it.

No. The manufacturer designs the B6 to work with the factory springs and to keep the original ride height.
Owners on user forums report that B4 OE-style replacements ride close to stock, and recommend the B6 for a more noticeable upgrade.
Rear shock replacement on this platform is a moderate DIY job for someone comfortable with jack stands. You'll need a trolley jack, axle stands, a 19mm socket and breaker bar, a 15mm socket and ratchet, and a 10mm socket with an extension. Owners on user forums advise raising the rear high enough on stands to let the shock drop free, and removing the trunk liner first to reach the top nut. Be careful with the liner clips, which can break if forced. Fastener sizes reported by different guides vary, so check the manufacturer's instructions and replace one side at a time to keep the old shock available as a reference.
