2014–2018 Subaru Forester & 2015–2021 Subaru WRX Piston Set with Ring Kit

A brand-new PRK4347 Piston Set with Ring Kit is one of the smartest upgrades you can make for the 2.0L H4 FA20F turbocharged engine found in the 2014–2018 Subaru Forester and 2015–2021 Subaru WRX. These vehicles are known for their responsive power delivery and high-revving performance, but worn pistons or failing rings can quickly rob them of that signature punch. Common symptoms like excessive oil consumption, blue exhaust smoke, loss of compression, misfires, or noticeable drops in boost pressure are clear signs your engine’s internals are no longer sealing or performing as they should. Installing a fresh piston and ring kit restores proper compression, improves combustion efficiency, reduces oil blow-by, and helps protect the turbocharged FA20F from long-term damage. This kit gives your Subaru the strong, reliable power it was engineered for. Whether you’re rebuilding, refreshing, or preventing future failure, Partsology delivers high-quality DNJ components at amazing prices, making it easier than ever to get your Forester or WRX back to peak performance.
