Supertech 93mm Bore Piston Rings Set for Subaru R93-SWF20057-4, 4-Piece High Performance
$102.01

If you're diving into the world of performance upgrades, the High Performance Piston Ring Set by Supertech is a solid choice. I’ve used these myself, and let me tell you, they’re built to last. These piston rings are crafted with some serious tech, so you know they’re going to hold up under pressure. Whether you’re hitting the track or just want a little more pep in your daily drive, these rings are designed to exceed the usual expectations.

Now, let’s get into the nitty-gritty. You’re looking at a 93mm bore setup, which is perfect for those Subaru builds. The specs break down like this:

  • 1.2x3.30mm
  • 1.5x3.7mm
  • 4.0x3.65mm

That’s a solid range for anyone looking to push their engine a bit. Each set comes with four rings, so you’ll have everything you need for a complete overhaul.

These rings fit snugly in Subaru engines, and they’re engineered to handle the rigors of performance driving. I’ve seen them clear some serious power without breaking a sweat. Just a heads-up, if you’re planning to run high boost or really crank up the RPMs, these rings will keep your compression tight and your oil control on point.

So, if you’re ready to take your Subaru’s performance to the next level, grab a set of the Supertech 93mm Bore Piston Rings. Trust me, you won’t be disappointed.
