Hi-lo Filter Vs K&n Air Filter

[Mookie]

Is it true that with a hi-lo filter , the turbo "psssh" sound is softer compared to when you have a K&N filter on?

Because I have test-driven 2 skylines and the turbo pssh sound was much louder on one compared to the other. What other factors may have made the difference?

Cheers

What is a "Hi-lo filter"?

Are you talking about the suction sound, or the BOV sound?

Really an amateur at this... Well its the psssh sound u hear when u change the gear.

That would be the BOV.

With a high flow fliter in the stock airbox, you should be able to hear it.

the only way to make it quiet again is to put the stock panel filter back in

the cars come with a stock BOV but the noise isnt really loud enough to hear so best bet is that its a new air filter. ive put 1 in mine and everybody thinks i got a BOV.
