Intake Whistle Fixed!

Hey guys, I didn't want to start a new thread on the topic, but I couldn't reply to other threads on this issue for some reason.

Anyway, after pulling the charcoal filter and installing an AFE Pro Dry filter, I had the loud whistling coming from the intake that lots of people are noticing.

I wasn't too eager to snip out the screen on the manifold gasket, but I found a part number for a toyota gasket with no screen on another forum!

Part number is 22271-50050, it was $5 up here in Canada. Took all of 10 minutes to swap out the gasket and the whistle is GONE!!

Should've taken pics, oops...

Anyway, here's a little recap... Remove engine cover. Loosen the 2 hose clamps on the connecting tube between the air box and manifold and pull the tube up and out of the way. Remove the 4 10mm bolts from the manifold and pull throttle body up out of the way. Pull old gasket with screen out, install new gasket. Reinstall throttle body, connecting tube and engine cover. Drive away whistle free!

K, pics uploaded. First is of the original gasket with the screen. You could definitely just cut the screen out if you wanted. But for 5 bucks to get a new gasket with no screen, I liked having the original to put back in if needed.

Next pic is of the throttle body (with the engine cover removed). The throttle butterfly is right in front of the gasket with the screen, so it makes sense that there could be some turbulance issues.

I have only driven around town since the change, but I haven't noticed any whistle so far and my average mpg has picked up a bit. I'll be out on the highway over the weekend and I'll see if there's any mpg changes there. I didn't notice any changes from the charcoal delete or the AFE filter....

Will this increase air flow? Whats the purpose of the screen gasket?

It might. On the other hand it might reduce it. Screens of this type can straighten the air flow, thus increasing it. I believe the technical term is "laminar". Just guessing at this point. It would have to be measured to tell for sure.

That short little section with the throttle butterfly, the gasket with the screen and then a 90 degree bend will definitely cause some pressure drop in the system.

There will be turbulence in the airflow after the throttle butterfly and then that turbulent air will hit the screen and cause the whistle. Kind of like blowing air over the top of a pop bottle. I'm guessing that by putting in a higer flowing filter, this became more of an issue.

If the screen was meant to straighten the air flow, they should've made fewer and longer "blades" in the tube. We use something similar in HVAC ducting called turning vanes to help minimize pressure drop in 90 degree bends. I'm guessing the screen is just there as a safety to keep any large chunks (of what? Charcoal filter maybe?) from getting past and into the engine.

Either way, my whistle is still gone and I'm getting the best mileage I've ever got in the truck. I was hovering around 20 mpg on the highway (17 to 23 ish) and had an average of 19.7 over about 60 miles. This was from the computer only though, I'll calculate it by hand when I'm going on a longer trip.

Does anyone know if this screen is still present with the TRD Supercharger?

I never noticed this whistle before the SC, and now I do. The sound is not the SC whine, I know the difference and there is TWO different sounds.

Screen is not there anymore on the sc.

Adjust your airbox lid to sit properly to elim noise.

I'm going to try this tomorrow because I just installed my AFE tonight after returning my K&N for the whistle issue. The AFE is definetly quieter in terms of whistling but feels like it's more responsive and making more power than the K&N.

I'll let you guys know.
