3 Lug ALS Valve

The 3 Lug ALS Valve was originally designed in 2011 and has been on race and championship-winning cars in RallyX, WTCC, WRC and others.

Featuring a 33.75mm (1.3287”) outlet port, air from the plenum or compressor (depending on the plumbing used on your engine) is fed into the primaries through 4 tubes with a bore of 12.70mm (0.500”).

Cold air is fed into the ALS through a Wiggins style aluminium fitting with a bore of 23.00mm (0.905”).

Designed to cope with the extreme conditions experienced during racing, the 3 Lug ALS Valve was designed with high performance and exceptional quality parts, so as not to compromise reliability:

  • Stainless steel casting
  • Steel 214N forged valve
  • Austenitic Stainless Steel spring - this is available in many different spring rates, depending on your boost requirement
  • Aluminium billet machined valve guide housing
  • Colsibro valve guide
  • Viton Quad Ring seal to valve stem
  • Top-hat style Nomex-reinforced fluoropolymer rolling membrane
  • #2 JIC Boost connectors – different colours to ensure reliability of plumbing
  • 3 Lug plate mounting system, supplied plate (stainless steel) and inlet air (Aluminium 6082 T6) adaptors
