Supertech Pistons 89mm Bore +2.2cc Dome for Honda Acura K24 K20 2001-2015, Set of 4 - P4-HK89-P4

If you’re diving into the world of performance upgrades for your Honda or Acura, you’ve probably heard about Supertech Pistons. These aren’t just any pistons; they’re crafted from a high silicone, enhanced 4032 alloy that’s got some serious engineering behind it. With added elements like copper, nickel, and magnesium, these pistons are built to handle the heat—literally. They’ve been tested at up to 42psi of boost with alcohol, and trust me, they hold up without a hitch.

The manufacturing process is where the magic happens. Supertech uses a two or three-step forging method that results in a fine structural grain. After that, they go through several CNC machining steps to ensure precision. The pistons undergo various heat treatments to give them high tensile strength and an even hardness distribution. This means they can take a beating while keeping your engine running smoothly.

One of the standout features is the contact reduction grooves that come standard. This little detail helps reduce friction, which is always a plus. The pin bores are honed and reamed for a precise fit, ensuring everything aligns just right. Plus, the wrist pins are made from cold extruded chrome moly steel, which is known for its strength. They come with wire clip locks to keep everything secure, so you can focus on the road ahead without worrying about your internals.

To top it all off, these pistons receive a phosphate dry lubricant coating. This isn’t just for show; it helps protect the rings from micro-welding and enhances lubrication in the skirt and cylinder area. It’s these little touches that make a big difference in performance.

Specifications:

  • Bore: 89mm
  • Comp Height: 1.181in
  • Dome/Dish: +2.2cc
  • Comp Ratio: 12.5:1
