1. Great Power Transfer: It’s like the "power conversion heart" of the engine—Brilliance H330 Piston 3006139 has super precise sizing and surface treatment. It fits tight with the cylinder wall and connecting rod, so it passes on the power from fuel burn super efficiently, no wasted energy. That means the engine keeps putting out steady power—especially when you’re speeding up or going up hills, no annoying power lag.

2. Tough & Long-Lasting: The high-strength aluminum alloy goes through a special heat treatment. It’s light (each one’s about 300-350g, might vary a bit by brand and how it’s made) but can handle hundreds of degrees of heat and the constant back-and-forth rubbing when the engine’s on. Plus, the piston surface usually gets anodized or molybdenum-coated—makes it even more wear and rust resistant, so it lasts way longer. Normal use? It can go 50,000 to 80,000 km (but depends on how you drive and maintain the car).

3. Perfect Fit: This piston’s made exactly to the original size standards of the Brilliance H330 engine. The combustion chamber shape on top, the oval shape and taper of the piston skirt—all precision-machined. So it fits perfectly with parts like the cylinder and piston rings. No extra tweaks needed when installing—just swap out the old piston directly. Makes repairing and putting it together way easier, no engine noise or air leaks from wrong sizes.

• Piston Top: It’s shaped specifically (like flat or shallow concave) to match the engine’s combustion system. Helps fuel burn better, less carbon buildup, and also eases the heat impact on the piston from burning fuel.

• Piston Skirt: It’s oval-shaped. When the engine’s cold, it fits tight against the cylinder wall. When it heats up and expands, it gets more round—so there’s always a good gap, no loud friction between the piston and cylinder wall.

• Piston Pin Hole: It’s above the skirt, used to put in the piston pin that connects the connecting rod and piston. The inside of the hole is super smooth (thanks to precision honing), so the piston pin and hole don’t wear out fast—everything moves flexibly.

• Ring Grooves: There are 2-3 grooves around the piston’s outer circle, for compression rings and oil rings. The depth, width, and how smooth the grooves are—all strictly controlled. So the piston rings fit tight against the cylinder wall—seal the high-pressure gas inside well, and scrape off extra oil from the cylinder wall, so oil doesn’t get into the combustion chamber.

• Brilliance H330 Piston 3006139 Key Features

• Top-Notch Power Transfer: Brilliance H330 Piston 3006139 acts like the engine’s "power conversion heart"—it has super precise sizing and surface treatment, so it fits tight with the cylinder wall and connecting rod. This lets it pass on fuel-burning power super efficiently, no energy wasted. Whether you’re speeding up or climbing hills, the engine keeps putting out steady power, with no annoying lag.

• Super Tough & Long-Lasting: Made of high-strength aluminum alloy that goes through special heat treatment—it’s light (around 300-350g per piece, varies a bit by brand) but can handle hundreds of degrees of heat and constant back-and-forth rubbing when the engine runs. Plus, its surface is usually anodized or molybdenum-coated, making it even more resistant to wear and rust. Under normal use, it can last 50,000 to 80,000 km (depends on driving habits and maintenance, though).

• Perfect Fit, No Fuss Installation: This piston is made exactly to the Brilliance H330 engine’s original size standards. The combustion chamber shape on top, the ovality and taper of the piston skirt—all are precision-machined. It fits perfectly with parts like the cylinder and piston rings, so you don’t need extra tweaks when installing. Just swap out the old piston directly, making repairs and assembly way easier. No engine noise or air leaks from wrong sizes, either.

• Smart Structural Design for Better Performance: Every part of the piston is designed with use in mind—its top shape (flat or shallow concave) matches the engine’s combustion system, helping fuel burn better and reducing carbon buildup; the oval skirt fits tight when cold and expands to a good round shape when hot, cutting down friction noise; the smooth piston pin hole keeps parts from wearing out fast; and the well-controlled ring grooves make piston rings seal gas well and scrape extra oil, preventing oil from getting into the combustion chamber.
