Fits all 2017-2022 Honda CR-V 1.5T models
Fits all models, including right-hand drive, international models, etc.
Overview
Important Notes
- Standard Bore MAF Housing does not require ECU calibration
- Big Bore MAF Housing requires Big Bore MAF specific ECU calibration
- Both Honda & KTUNER provide Big Bore MAF base map calibrations
- Compatible with PHEARABLE TUNE when selecting the Two Step Performance "TSP" Tune & "RACE MAF" options
Technical Notes:
Our CNC machined billet aluminum MAF housings are designed to provide *factory-spec fuel trims (-4% of factory STFT and LTFT) for optimal drivability and performance. This SRI uses a 4-inch air filter and offers a choice of two different MAF housings: Standard Bore and Big Bore. Both housings utilize the factory MAF sensor but feature different diameters and profiles. As noted above, the Standard Bore housing is designed to provide factory-spec fuel trims without any tuning. The Big Bore housing requires tuning as it allows for 50% more airflow compared to the Standard Bore housing. This increased airflow reduces pumping losses and creates an unrestricted air path to supply ambient temperature air to the MAF housing.
Customers can use the MAF housing conversion kit
Performance Gains:
- 15 HP and 12 ft/lbs torque increase over stock using the Standard Bore MAF housing without a tune
- 20 HP and 15 ft/lbs torque increase over stock using the Big Bore MAF housing with a Big Bore MAF base map calibration on Hondata or KTuner
- Larger gains can be seen at higher power levels with custom tuning

This is also a Long Term Fuel Trim graph, but using a Cold Air Intake (Standard Bore MAF) and factory ECU mapping.
This is another Long Term Fuel Trim graph, using a Cold Air Intake (Standard Bore MAF) and +6psi Hondata off-the-shelf map.
Note how consistent and similar all the LTFT graphs are. Each graph is within -4 LTFT.
Above is a graph of Short Term Fuel Trim using a stock intake with the airbox and factory ECU mapping (stock car).
Here is a Short Term Fuel Trim graph using our Cold Air Intake (Standard Bore MAF) and factory ECU mapping.
This is another Short Term Fuel Trim graph using a Cold Air Intake (Standard Bore MAF) and +6psi Hondata off-the-shelf map.
All STFT graphs show identical curves and consistency.
Before Ordering
〇Regarding Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether parts can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model using the tabs on our home page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○Regarding Shipping
Shipping costs are paid at the time of settlement. Estimates for shipping can be automatically calculated on the checkout page by entering your delivery address. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automatically calculated amount. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international delivery takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please inquire about the delivery date in advance. All products are transported via air freight. They are never shipped by sea freight.
○Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Our products are basically designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese Vehicle Inspection system," and we cannot provide structural calculation papers or similar documents for that purpose. Therefore, all parts are sold for use on "circuits, private land, or off-road," and you are responsible for their installation and use at your own risk.
○Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be cases of shipping damage to the packaging or the product itself. We will handle returns, refunds, or exchanges only if you contact us within 7 days of receipt regarding items with shipping damage, defects, or incorrect orders. Please note that for products sold through our company, warranty support will be provided "only through us." We do not provide support through other companies or agents located in Japan.
