RH 0.25 Oversize Piston Set for Subaru Boxer 🔧
Why you need it
After high mileage, heat, or detonation, the cylinder can wear or score. A 0.25 mm overbore with a matching right‑hand piston restores factory compression, oil control, and smooth power. This set is built to OEM geometry so your engine idles clean, pulls strong, and stays efficient 🚗.
How it works
The lightweight aluminum slug rides the cylinder wall via a low‑friction coated skirt. The ring pack—top compression, second scraper, and oil control—seals combustion, reduces blow‑by, and meters oil. Correct crown shape manages swirl and knock, while precise pin fit keeps the rod true. Balanced weight keeps the flat‑four smooth ⚙️.
If the old piston is worn or broken
Expect cold knock, loss of compression, misfire, oil burning, and rising crankcase pressure. Cracked lands or collapsed skirts can score the bore, damage the head, and even seize the engine—costly failure ❗ Replace during a 0.25 re-bore, set ring end gaps, align the arrow, and verify piston‑to‑wall clearance 🛠️.
