Grease Trap For Solenoid
This QEV is perfect for the Ion.
It acts as a grease trap for the solenoid.(No more cleaning it out)
It also boost the gas efficiency when the board settings are right.
You can also lower your imput pressure greatly.
Only bad thing is the threads are not the strongest things.
If overtightened it will leak/not function well.
Buy a new one they are cheap.
Great product, cheap, helpful and it gets the job done.
