Choosing a DNA air filter starts with the exact application, not simply the motorcycle brand. This guide helps you check fitment, understand the difference between replacement filters and intake upgrades, and plan the right care for your filter.
Always follow the current instructions supplied with your specific DNA product. Cleaning methods, setup requirements and maintenance intervals should not be assumed to be identical across every application.
Find the correct filter for your motorcycle
Check your motorcycle's make, full model name, model year, engine size and variant against the product listing. Registration year alone may not identify the correct filter. Tell us if the bike has a modified airbox or other intake changes.
Start with Shop by Bike. If the application is unclear, read our fitment-help guide or ask our team before ordering.
Replacement filter, airbox cover or intake kit?
Replacement air filters
Check whether the product is intended to replace the original filter in the standard airbox. Confirm the product code, listed applications and any installation notes before purchasing.
Airbox covers and Stage 2 products
An airbox cover is not necessarily a replacement filter, and a Stage 2 listing is not necessarily a complete kit. Read the contents carefully to establish what is included and which other components are required.
Do not assume that a cover or kit is suitable for a standard setup simply because the model name matches. Check the manufacturer's fitting and calibration requirements for the exact combination.
Service kits
Check that the cleaner and treatment products are approved for your particular filter. A service kit maintains a compatible filter; it does not replace a damaged filter or correct an unsuitable intake installation.
Will an air filter upgrade require ECU tuning?
There is no universal answer for every motorcycle or intake product. Confirm the manufacturer's requirements for your exact filter, cover or kit, especially if you are also changing the exhaust or already have an ECU calibration.
Do not assume that an existing map supports a new intake configuration. Read our exhaust installation and ECU tuning guide for questions to discuss with your installer.
Checks before fitting
- Compare the product code and contents with the item ordered.
- Read the supplied installation instructions before removing the original filter.
- Check the airbox, sealing surfaces and mounting arrangement as directed by the manufacturer.
- Keep dirt and loose objects away from the exposed intake.
- Confirm whether any filter preparation is required. Do not add oil simply because the filter is new.
- If you are unsure about installation, use a qualified motorcycle technician.
Never force a filter into an airbox or modify it to make it fit. If the dimensions or mounting arrangement appear wrong, stop and ask for help.
When should I inspect or clean my filter?
Use the inspection and servicing guidance for your filter and motorcycle. Riding conditions matter: dust, heavy contamination and demanding use can change how frequently inspection is needed.
Avoid applying one mileage interval to every motorcycle. If you cannot find the relevant instructions, ask for the guidance associated with your product code.
Cleaning and care checklist
- Identify the filter and its care instructions. Confirm the cleaning products and process specified for that filter.
- Remove it carefully. Prevent dirt from entering the intake and follow the motorcycle's access instructions.
- Inspect before cleaning. Look for damage to the filter medium, sealing areas or frame. Ask for advice if anything is torn, distorted or deteriorated.
- Follow the approved cleaning method. Use the specified cleaner, quantities, application times and rinsing procedure. Do not substitute aggressive solvents or unapproved cleaning equipment.
- Allow the specified drying process. Do not rush drying with heat or compressed air unless the manufacturer explicitly permits it.
- Apply treatment only as instructed. Where oiling is required, use the specified oil and amount. More oil is not a substitute for following the procedure.
- Refit and check the seal. Follow the installation instructions and ensure the filter is correctly seated before closing the airbox.
This checklist is an overview, not a substitute for DNA's product-specific servicing instructions. Do not run the motorcycle without the correct filter fitted.
Common mistakes to avoid
- Ordering by registration year without checking the model generation.
- Confusing an airbox cover with a complete filter kit.
- Assuming a filter, exhaust and ECU map are compatible without checking the exact configuration.
- Cleaning or oiling by guesswork rather than following the supplied guidance.
- Refitting a damaged filter or one that is not ready for installation.
Need help choosing a filter or service kit?
Contact Motorcycle Performance Store or email info@motorcycleperformancestore.co.uk. Include your motorcycle's make, model, model year and variant, the product link or code, and any intake, exhaust or ECU modifications.
If you already own a DNA filter, include its product code so we can help identify the appropriate product information before you buy maintenance supplies.
