Supertech Valves +1mm oversized D-series valves are made in one piece forged stainless steel. Intake valves in +1mm o/s are made in SAE EV8 (UNS S63008) and +1mm o/s exhaust valves are made from Inconel 575.

Inconel 575 is a Nickel based alloy material used for exhaust valves in engines that reach very high temperatures and its use is growing with the application of turbos and superchargers. These valves are hollow and filled with Sodium. This will ensure cooling of the valve by removing heat from the head of the valve to the stem, providing better temperature distribution, and lowering head temperature.

Supertech Performance apply's different heat treatments to this material to obtain different hardness and ductility in accordance to application and budget (Street Performance or Heavy Duty Racing).

  • 88-91 Civic/CRX 1.5liter D15Bx
  • 88-91 Civic/CRX Si 1.6liter D16A6

Good socks they work.
Size: 2 pairs black L
I normally wear size 13&half to 14 men's, and these fit me ok. They sit just below the ankle. They can get a little tight for me so you should look out for that if you are on the thicker side. But they work as advertised and help moisturize your feet. I recommend wearing them if you're going to just be hanging around home for a bit in one spot as they can be a little slippery to walk in if you go fast. Would not recommend going up and down stairs.

REALLY unsafe to walk around in these
Size: 2 pairs black L
They do what they are expected to do, but should only be used if you are stationary. The gel base makes for very unstable footing if walking around

These work
Size: 2 pairs black L
My husband loves these they help his very dry feet. As others have stated they are extremely difficult to walk in so have to be careful but they do work nicely.

Potential Fall Risk
Size: 2 pairs black L
While these socks do indeed help soften rough skin on your feet, there is a risk of falling while wearing them. Although they have treads on the bottom, which would indicate they’re safe to wear with nothing else, when you put moisturizer on and then wear them your foot can slip inside the sock . This causes you to lose your balance and fall, which happened to me. I’ve thrown them out.
