2023 honda civic si cold air intake

Honda on Wednesday revealed that the 2023 Honda Civic Type R will have 315 hp, making it the most powerful Honda-badged vehicle ever sold in the U.S.

Honda also detailed what upgrades led to the power increase, along with what tweaks were made to the transmission and suspension for the next-generation Type R.

More power, more cooling

To start, the Civic Type R's 2.0-liter turbo-4 has been massaged to produce 315 hp and 310 lb-ft of torque. The power increase over the outgoing Type R's 306 hp and 295 lb-ft of torque comes via three updates: a redesigned turbocharger, an increased air intake flow rate, and a new, more efficient exhaust system.

The turbocharger features an optimized shape, size, and number of turbine wheel blades, Honda explained. That together with a redesigned path for the air intake allows the turbo to more efficiently generate pressure in a wider range.

The larger grille opening on the 2023 Type R feeds a new, larger radiator and larger diameter fan aimed at improving engine cooling while ensuring sustained performance.

An active valve in the new exhaust system's center pipe opens at a higher rpm than before, but Honda didn't note at what rpm that magic door opens.

A lighter flywheel and newly optimized shift pattern for the 6-speed manual transmission round out the upgrades. Honda's also installed a rev-matching system in the 2023 Type R like the one in the 2022 Civic Si.

Tweaked suspension, upgraded brakes

Based on the 11th-generation Civic, the new Type R is longer and wider than before. The 107.7-inch wheelbase has grown 1.4 inches versus the last Type R, and the track is 1.0 wider in the front and 0.75 inches in the rear.

To accommodate the longer and wider Type R Honda engineers retuned the front strut and rear multi-link suspension to improve straight-line stability. Honda said steering feel has improved.

Hauling the Type R down from speed are two-piece Brembo brake rotors up front, hooked to a retuned brake booster that enhances feel and controllability, according to Honda.

Honda hasn't said how much the 2023 Civic Type R will cost when it goes on sale this fall, but it will be built at the automaker's Yorii Plant in Japan.

Maybe some kind of baffling or flaps that regulate airflow coming into the manifold

level 2

Bingo, sorta

Helps with the turbo back pressure by increasing the manifold capacity, helps with lost throttle response

level 2

It’s the inlet pipe for the turbo. It’s flatter than the previous version probably to make clearance for the hood.

try search 2023 k20c1 engine. there is a photo of cut thru engine and that box look like no function

It could be a resonator chamber like the CRV has, just smaller.

After looking at that one I think this is the most likely scenario.

My Honda has one too. They seem to be the only brand who does this and nobody can ever figure out why lol. I guess tiny engines pulling a lot of air get noisy.

Are these the motherboards?

Who wants to know? Honda tech here that just learned about it today and interested in seeing one and getting service manual on it to know more.

level 2

What I've been told is this is an updated feature learning from the last gen type r. Again awaiting more info with the service manual but its going to help cool the air further for the charge since the last gen had an overheating issue on the track. Will update as I learn more.

Man I just need to know how to get one. Money is burning a hole in my pocket already.
