Wiseco sport compact pistons are forged and machined in-house and receive a full compliment of power enhancing features. Light weight forgings, millimeter ring packs, extra-strength forgings, gas ports, skirt coatings, offset pins, and a variety of other features are available to insure each engine exceeds our customer’s expectations. Optimized skirt profiles minimize rock and provide long skirt life in stroker applications. 

All machining is done on the newest CNC equipment to insure the tightest tolerances in the industry. Our Wiseco sport compact pistons are top of the line performance parts, built for the demanding consumer that wants nothing but the best. Some of our sport compact pistons are even matched with high quality NPR Steel nitrided rings with napier style 2nd rings.

Below are just some of the popular features found in our forged piston product lines:

  • Valve pocket designs allow maximum flow around the valve, allowing the use of oversized valves and high lift cams.
  • Piston crown shapes are designed to promote the maximum intake charge efficiency through a scavenging mixture ‘Cross Flow’ during intake and exhaust valve overlap. More fuel and air equals more horsepower.
  • Piston domes are designed for optimal quench during the compression/ combustion cycle, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.
  • Precision machined ring grooves with proper orifice/ accumulator volume feature calculated groove root diameters and axial widths, providing excellent surface finish and flatness, maximum ring seal, and minimized blow-by and oil consumption.

Very nice very very nice
Style: CA10467
Honestly I didn’t use it yet but just by inspection it. Looks very good. On thing I have to say is. Amazon did it again. Perfect. The outside box was a little dented and slightly crushed on the corner but the inside box that holds the air filter was perfect. Me being a delivery driver at one time am amazed that the packages always come delivered in perfect condition. I know how easy they can get damaged. Great job Amazon and the drivers and the whse and package dept. great job Update, I just put the air filter in my Honda and it feels faster and more responsive. I will be buying this air filter again. I bought a spearhead air filter for my tundra , and it’s a good filter but I think I am going to switch to a kax filter for two reasons First I said I put it in my Honda and it feels faster and responds quicker. Second. I know it’s not a good reason but I like the color. But I really feel the difference.
