Innovative high performance piston skirt design that provides:

1. Smaller piston to bore clearance

2. Less noise

3. Better ring seal

4. Higher power

5. Durability


Features:

Anti detonation grooves: protect the top ring by disrupting detonation waves and reduce piston-cylinder contact in high temperatures and engine RPM conditions.

Accumulator groove: accumulates residual combustion gasses reducing top ring flutter and improving seal.

Pin oil lubrication by broaches and oiler to reduce friction and increase durability.

Piston rings 81mm set

Contains 01 complete set for 4 cylinder engine.
Compatible with SPA Super A, with 1.5mm / 1.5mm and 2mm channels.
Ring thickness:
1st ring 1.5mm - Made of carbon steel, which is 35% more resistant than cast iron and on average 30% lighter. With DLC (Diamond-Like Carbon) treatment, which is the application of carbon particles, whose physical and chemical properties are very close to those of the diamond, providing greater resistance to the material and reducing the friction of the surface, which significantly reduces friction when working against other surfaces.
2nd ring 1.5mm - Made of cast iron.
3rd ring 2.0mm - Manufactured in 3 pieces, which guarantees easy maintenance, better stability in the control of the oil film and improves the oil removal through the piston lubrication holes, as it has a better area for displacing this oil.

        Mid jeans. Not bad but not amazing
        The button is super wobbly and feels like itll break at any moment. The zipper quality also isnt great even when im not wearing them the zipper cant go above like 80% when I wear them itll slowly unzip if I twist or turn my body over a few hours. There's also not a lot of room for your bits so maybe go a size up. Other than that rhe material is comfy and has a bit of give so unlike other skinny jeans you dont feel restricted. The color is also super vibrant and lovely. Im not gonna return them unless the zipper breaks but idk if ill buy another pair if the button is like this.
