INSTALLATION:
Important Notes:
- NO ECU CALIBRATION REQUIRED
- Increase airflow volume and lower intake air temperatures
Technical Notes:
We understand that not everybody wants a "cold air intake" and not everyone wants to be limited with an air box ONLY option. Our modular design allows customers to modify or tailor their intake setup at anytime to suit their personal driving needs. This cold air intake air duct is the best way to provide additional airflow and cooling without sacrificing airflow to the radiator.
The High Volume "Plus" Cold Air Intake Duct is transforms our standard High Volume Intake System into a true cold air intake by introducing cool air through the inner fender liner, which increases airflow and lowers intake air temperatures. This design also increases intake system efficiency when driving in low pressure (drafting) zones. The HDPE rotomolded duct also helps to reduce heat-soak.
Kit Includes:
- (1) High Volume Intake "Plus" Cold Air Intake Duct
- (1) 4-Ply Silicone Intake Hose
- (2) 304 Stainless Steel Worm Drive Hose Clamps

Great intake
"purchased this for my 25 Honda Civic Si. Installation was simple. It does not make the engine loud like others do. Oem look while maintaining high performance. Recommended"
2025 Civic SI
"Awesome with HVI!!!"
"Thank you very much !"
"Timely to install compared to the air blocks but worth it if you care for induction noise as well as cooler intake-temps."

Great exactly what i was
"Great exactly what i was looking for"
Support team amazing
"Definitely a noticeable difference and I love the sound compared to stock. Only issue was the MAF sensor housing didn’t come in the package but when I reached out to them, they sent it to me overnight air. This is my first PRL purchase and it definitely won’t be the last. I love their support and understanding and quality products."
Q&A
- Do I need the intercooler resonator delete in order to fit this Duct? I already have the HVI installed.
- No you will not need the resonator delete to install the duct.
- When will be able to get our hands on the duct kit for the 11th gen SI?
- Greetings. The Intake Duct is in stock for purchase. https://prlmotorsports.com/products/2022-honda-civic-1-5t-high-volume-plus-auxiliary-cold-air-intake-air-duct?_pos=1&_psq=PRL-HC11-15T-INT-HV%2B&_ss=e&_v=1.0
- what are the gains will it be any louder with or without it on the hvi
- Greetings. The HVI will increase Hp 10+. The Duct will increase airflow and lowers intake air temperatures. This design also increases intake system efficiency when driving in low pressure (drafting) zones. It will sound amazing.
- Will I be prone to hydrolock by installing this? It gets very crazy in my area.
- Greetings. You should not have any problems. Avoid standing water or puddles that you're not sure of.
- Is there a air duct for the 2.0L prl air intake
- Greetings. No, The HDPE rotomolded air box utilizes the factory air guide + seal for optimal airflow and heat-soak reduction.
