So it looks like there might be an opportunity to make a custom CAI for the Type S. I did a breif examination of the intake system today. For one, theres a good amount of space once the box is removed. There's also a lower chamber that's connected to the underside of the box. I didn't have my scope with me to see if this chamber is open to the outside or not though, so I'll take a deeper dive over the weekend maybe. If it is open, then we can assume a CAI won't do a whole lot other than increase intake sound. If its closed off, this may be to resonate sound in the system and/or collect any kind of condensation that may occur. MAF positioning would remain the same (right after the first 45* bend). I feel like there's a lot of resistriction in this system, especially if the only air entry comes from that front bumper snorkel area. It also benefits having the JB4 on the car as well. I'm still using the stock map until I get my first 1500 or so miles on it and this will allow me to monitor logs on a stock map with an upgrded intake system.

 

I forgot to mention one main concern. The wheel weel covers are slotted, so water spray off the tires will definitely have to be accounted for.

 

If you check the thread someone did that but a short ram






I have a 2.0T and did an enclosed air box K&N cone with a PRL Motorsport silicone pipe.

 

I wonder if there's any significant increase with IAT using the short ram. Do you have a link to the thread?

 

I made this already by replacing the resonator with secondary air inlet, it improved the OEM temperature. Water intrusion is not possible because the OEM inlet is untouched and larger. Even the secondary inlet is fully submerged with water it will not suck water, it’s physics.

I already tested this with water contact strips and drove my car to a two consecutive pouring rain and 2” puddle. The vent by the driver side wheel doesn’t get a lot of water splash due to the blades are slanted upwards plus the car is not going reverse all the time to get the splash forward.

We tested it to 5 Type S and all showed identical results, 2-4 degrees cooler than OEM during cruise control at 65 mph, even more cooler during acceleration and WOT.

It’s live on Etsy for 3 days now, just search “TLX Type S Secondary Air Inlet”.

Here’s the product description.

Snorkel (Secondary Air Inlet) for 21+ Acura TLX Type S

The secondary air inlet is designed to facilitate the suction of cooler ambient air into the engine's primary intake temperature. This supplementary pathway serves to optimize engine efficiency and performance by moderating the temperature of the air charge, thereby enhancing combustion dynamics and promoting smoother operation.

Replacing the blocked intake resonator with a secondary air inlet has been tested to improve the OEM intake temperature with a plus of creating engine suction noise.

Even if the secondary air inlet were fully submerged in water, the design features and positioning of the inlet eliminated the risk of water intrusion.
The primary OEM air inlet is positioned higher and larger, ensuring that water, which is denser than air, settles below it.

This design elements work in conjunction with the durability of the materials used, such as stainless steel air filter, clamp, and ASA material known for its durability, UV resistance, and high heat tolerance.

 

Any media on what the sound is like? I've been eyeballing this but not sure if it's going to sound like the car has a vacuum leak from the outside. Any discount love for forum peeps?

 

I do but it’s too big to upload. Are you on the TLX Type S Facebook group?

 

It’s not a drastic sound like HPS of course but you will hear the turbo spool and recirculation when you let your foot off the pedal. Again, the slight increase in sound is just a plus. The main benefit really is the cooler air.

 

I don't do social media. I only registered here to buy something in marketplace after I bought the car.

Thanks for that. Ordered!

 

Shipping today! Do you have ktuner?

 

No. JB4.

 

 

3D printed?

 

yessir!! Takes 20 hours to make the secondary inlet. I use ASA material (ABS like) than can withstand up to 195f temp.

 

Very cool, which machine are you using?
