put a 14x3 ac on my 01 318 and it seems I can hear a sucking noise, I did find a bad piece of tube on firewall,rider side, replaced and it still noisy, maybe this is normal, please advise me as what I need to do. Thanks.

 

A somewhat loud sucking noise is normal. You can hear the air being sucked into the intake.

My K&N Generation I FIPK (very similar to 14x3) on my 1995 Dakota (318) made the same noise. I was worried at first about it, but nope, its normal.

 

ok thanks, not to worry.

 

Also check thru the fins and make sure that your TB gasket isn't hanging over into the air column. It will suck but loud sucking indicates a restriction. If you trim theTB gasket or reposition it correctly you can lose a lot of the suction sound.

 

sounds good ill take a look see, Thanks.

 

Sorry for the spelling, trying to get it all in before I time out.

 

mine does that for about 4mins when i first start it up then it goes away and it runs smoother. otherwise on the throttle its not as noisey but you can still hear it even with my exhaust. hey for 30 bucks and to loose a couple mpgi aint complaining LOL

 

Normal for an open element to make sucking sounds. When thegasket under themis not centered correctly they tend to whistle If the noise level changes after it warms up, could be a worn plunger on the IAC.

I hate the sucking noise no matter what it does for performance! And be prepared to lose MPG!

 

I'm puuting the oem Air box back on and compare.
