Valve 2000 Race/Street Stainless Oversize 9x41mm 45 degree Exhaust
[20009EVOS]
$18.00

Stainless steel alloy 41mm oversized exhaust valve for 2.0 Alfas with standard  9mm stems. This 1mm oversize does not require oversized seats in the head since the stock seat is 41.5mm OD.

Our 45/41 mm oversize valve combo has done wonders for both street/performance and race engines.  Our race engines with these valves produce 200 HP on our conservative Dyno.  Street performance 10.5:1 makes 170.

Click here to see our 45 mm companion oversized intake valve.

These features dramatically improve flow.

  • 1mm larger window for mixture to enter and exhaust gas escape increases torque at low RPM range
  • 45 degree seating -- increasses flow
  • exposed stem is reduced to 8mm in port
  • special backside design
