Leading evidence: 'performance graph will be more balanced' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'performance graph will be more balanced' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Use additional screws and do away' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Makes me wonder why they didn't just use additional screws and do away with the flimsy plastic tabs that are built to break.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

1.) Un-screw the one phillips head screw at top center of side air intake...
2.) The molded air duct and the intake grill are still attached by three delicate plastic tabs at the three points... The best way to remove this is gently insert your fingers through the grills into the intake at the points circled in red and gently try to free the tabs... All three points come forward towards you, but if one is stuck or gets caught it will break...
3.) Inside the drivers side air duct you will find a snorkle... The snorkle is added to most US cars for noise restrictions. Now this piece is attached by no screws or tabs, but it most likely will give you some troubles removing... The best way is to remove this, just grab a hold of the long snorkle (not the small dish on the end)... Now wiggle it from left to right and vice versa while pulling out towards you. This works, but might take a little effort.
4.) This is what the intake is going to look like after the snorkel is removed... Just carefully insert the three tabs back into their points... Make sure that all three are tightly in by pushing the airduct cover (not the grill)... Insert your 1 screw into top center of cover and you are done.
Here is a video to further assist ;

Thanks, Ohana for the write up. You are very correct about the delicate plastic tabs. Mine are completely broken on the engine cooling (passenger) side, and 2/3 broken on the intake (driver's) side. Really the grills are just held on by the upper screw. Makes me wonder why they didn't just use additional screws and do away with the flimsy plastic tabs that are built to break. And they cost $60 each to special order from Suncoast. I will also add there is an inner screen (to keep cig give butts and the like out of the intake) on the 986.2. This is easily removed with one screw.
Now, on the result of desnorkling - I have to say I was hoping for more. I'd say it is not noticeable on start up, idle and lower revs. Above 4K, I think there is a small, but noticeable deeper note.

Hello,
i'm not shure if that desnorkling has any advantage at all. The snorkel has a specific length and volume. So it is optimized for a specific resonance. Also the intake part of the snorkel has a rounded design. Also the me that is not a restrictor, because the diameter at the end of the snorkel is the same. And even if it is a little smaller at the start this helps to optimize air flow.
Would be interesting to put the car on a dyno and see if there are differences with and without snorkel. I suspect the performance graph will be more balanced with snorkel.

Hi Smallblock,
It's has been dyno'd by bisimoto back in 2009 at his shop, he provided proof of the small increase in WHP & Torque . Look it up you'll see the document.

Hi 986ohama,
thanks for the hint. What i found is that:

Because i couldn't see the graph i color corrected it.
red = with snorkel
violett = without snorkel
The biggest hp difference is above 6.000 rpm. Not the rpm speed range i'm often.
There is a difference in torque. If you look very careful you'll see a loss below 1.800 rpm. That is a rpm speed range i'm often.
I think if you really want more sound from the air intake i think you'll have to redesign the snorkel in a way that it looks like a trumpet.
Regards, Markus
Cool DIY!
I'm seeing a lot of room in there. Can also picture an electric blower controlled by Pulse Width Modulation (PWM) hooked up onto the RPM range signal (tapped in the ODB or something).
Read poor man's SuperCharger, would that work?!
