tundra sound like a turbo when shitfing

hello new to forums. I hear a low pitch air sound like a turbo like sound from the engine. I opened it up I noticed it does have a trd air intake not aftermarket with a sticker filter can be cleaned with cleaner that can be bought at Toyota. I'm thinking that the turbo sound hiss i am hearing when acceleration happens right. its not alot but i hear it during some accelerations. I have a 5.7 lit crew max with the tow package extra torq that what sales man told me like I said I opened engine it does say trd on the air intake take cover. any thought if I'm right.

 

Welcome!

 

thanx

 

If its a whistle sound its normal due to more air going into the intake. There is a screen in the throttle body that is causing the whistle.

 

so it is normal thanx i do have a modified trd air intake too right I had 15 4.6 lit crew max and it was a huge box this is much smaller than that ad it did not say trd on it ill take pics tomorrow any thoughts on that.

 

Yeah if its the one that says trd on the top piece, it also should have a rubber air accelerator going into the pass side fender to grab the air better.

 

I'm not sure I'll take pic tomorrow and post it this is my wife's she was worried i told her I think it that red intake thanks for help guys

 

^^^^^
This, totally normal with an upgraded intake. Cheap part and easy fix. If not, it doesn’t hurt anything.

 

Mine does it when i put a cold air intake im used to it. I tell people its my turbo spooling up lol
