I am getting a strange burping or gurgling sound from the intake (open K&N) at idle. It goes away when I go above 1500-2000rpm or so like some valve or door shutting?? I sounds the same as if you were to start your car with the intake pipe from the intercooler taken off. GRRRRR. any ideas?

 

I had that too, Dave said all the aftermarket intakes make that noise.

 

mine does it to. Try unplugging your air pump and you will hear it quiet down. Actually, if you do away with your air pump altogether and plug that pipe that feeds the air from the air pump to the intake...it will silence everything !! Once I get my midpipe on...I am going to get rid of my air pump.

 

Thanks, But That was the first thing I checked. I don't have an air pump and the hose is blocked off. It just started a few days ago ?? I haven't changed anything on the car for a while.

 

Are you sure it's not your coolant hose or something? Just checking..

 

Naw It's an air pumping sort of sound
