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).

Available for the following D-series engines:

  • 88-91 Civic/CRX 1.5liter D15Bx
  • 88-91 Civic/CRX Si 1.6liter D16A6
  • 92-95 Civic SOHC VTEC D16Z6
  • 96-00 Civic SOHC non-VTEC D16Y7

Great suit set
Color: Light Grey, Size: 4
It is incredibly attractive and includes everything a young child needs for a special occasion. The material is a 75% polyester and 25% linen blend, and the outer fabric feels remarkably smooth. Its unstructured design allows for an attractive, natural drape, and the blend conveniently allows for machine washing at home. As is typical with linen-based materials, the fabric can be naturally stiff and prone to wrinkling, so I recommend ironing or steaming it before use. The lightweight feel makes it an excellent choice for the spring, summer, and fall months. Overall, this suit offers exceptional value for the price.

Samsonite? I was way off!
Size: 8, Color: Light Blue, Size: 8, Color: Light Blue
Linen was a nice enough material and slightly distracted from the dumb&dumber blue motif. The regular suit material would have been a full homage. It is what he wanted so this was a fair compromise. Stats/ he is a size 8 in most brands, 51in and 60lbs. Purchased an 8. A size 7 would have been a better choice and more tailored look but this fit fine in the important places and he has room to grow. Short notice, quick shipping and fair quality for the price. May your Harry Dunne love it as much as mine did.
