Hi everyone. I have a question. I want to use some black flex tape to seal off the lower not upper parts of my k&n typhoon air intake. I mean where there are openings on the left and right. Can anyone recommend this?

I took pictures of the left (only lower section) and right (lower section) of the intake. That’s what I want to seal off. I figured it would help keep cold air in the intake area since cold air sinks and hot air rises.

let me know what you think. Thanks

I think if you still have your stock intake you should put it back on.
My 2 cents.

 

^^ this. The stock intake is hard to beat, and on top of that doesn't cause driveability issues like the Typhoon and some other cheaper hot air intakes.

You can tape it if you wish but things happen quickly under the hood, there's no time for air to rise or fall by convection. It won't have any effect.

 

Thanks. The only concern I had was the chemicals in the tape getting into the air and therefore the air intake. Thanks

Has anyone ever done anything like this before?

Tbh, the concept seems sketchy.
True, hot air rises and cold air sinks in a vacuum, but if you seal more of the area around the intake, do you think you could be trapping the hot air around the intake?

There will be some turbulence around the airbox so will the 'cold air' actually sink?

Need that venmo info to pay for my popcorn.

 

You mean a sealed airbox that gets air exclusively from the front? Yes. Mazda. When they designed the RX8 intake.

 

Op,

If you haven't figured out from the posts so far, the K&N intake for these cars is about the worst option of intake available. If you have other intake options we'd really suggest going that route. Proven power loss, terrible idle conditions, etc.

That being said, if you are worried about engine bay heat, I would be more inclined to find a way to have the air filter mounted outside of the engine bay onto the front crash support bar. (through the hole in the front of the stock airbox location) They make some affordable accordion style intake tubing for things like this. EXAMPLE

 

lol, it was all I could do not to go into full-trolling mode the other day …

but adding to the post above, it’d be better to add the Racing Beat ram air duct

but then also to eventually go full-CAI with their filter box too

Thanks guys I did use the flex tape and was able to seal the box just enough as to where the battery and fuse panel start and end and the bottom of the intake. Seems to work a little better.

the one thing most people overlook about the commandment to not bear false witness/lie is that it also applies to them not lying to their self.

why do people dis the k&n typhoon v2 intake so much? is it because it is not sealed off from the rest of the engine? mine is an 04 rx8, and it has the side vents on the front fender panels to exhaust some of the hot air out of there. It also sucks in the cold air from where the stock air box did - right in the front of the dirt tray. Anyone? Mine seems to be running fine. Just curious.

Thanks,

Chad

 

Because it doesn't handle airflow properly and reduces overall airflow to the engine, and can cause turbulence at the MAF which causes idle instability and in the worst case misfires and poor running. The problem exists with other intakes too, but the net net is it's power-losing modification even if it doesn't present driveability problems.

Nothing to do with hot air, especially at speed, which is why taping gaps is pointless.

 

I reset the ECU and from what I understand it reprograms the idle trims too. Wouldn't this inturn program the airflow entering the car, and therefore understand the air entering the intake. That's just what I understand. I did this after changing spark plugs, wires, and coils and there is a big difference.

Thanks,

Chad

 

There is a difference between asking questions to understand vs defending a product / biased decision. It was explained well by Loki. Its been proven. That intake is inferior to an OEM intake. The only intakes worth considering are the Racing Beat intake or AEM. Nothing else. Sorry to break it to you. If you like the intake for its looks, sound or whatever that's fine, but note you are losing power, and will run into idle issues.

 

Idk for sure, but I think the Mass Air Flow sensor can't do anything but 'read' the 'Air Flow'.
Air intake is affected by the intake, and can't be altered by resetting the ECU.

I wouldn't bet my life on it, but I'm reasonably sure.

Also anytime plugs, wires and coils are changed and the reset is done there's usually a noted improvement.

Nothing to do with the intake of air unless you went from a really dirty filter to a clean one.

 

The ECU is always learning, so resetting it doesn't change anything in the long run. In some very specific cases that have nothing to do with the intake, it's a troubleshooting step, but that's not applicable here. Measuring the airflow incorrectly is one thing, actually having less airflow with which to make power is another and probably more important one. Read back this forum, there are years of history, the car has been around for a bit

"programming the airflow" is not a thing.

When you changed the ignition components and reset the computer, how much of the change do you think was due to, you know, having a working ignition again?

 

May I have extra extra buttah?

 

 

Thanks.
