INTAKE SERIES

【SUPER AIR FILTER】

New stock replacement type air filter utilizing newly developed dry non-woven fabric filter.
High dust collection capacity and low resistance are implemented together at a high level.

Newly Developed Dry Non-woven Fabric Filter

• The density gradient structure where filter density becomes higher with each layer ensures all sizes of dust and other particles are caught in the most effective way. Optimizing the fiber components reduces the ventilation resistance.

Low Resistance & High Dust Collection Capacity

• Even though the intake resistance is reduced, the dust collection capacity is higher than previous model. (Collected more than 95% dust volume during in-house testing) Reliably capturing dust to provide clean air to the engine.

Long-term Low Resistance

• Even after long-term use of the filter, the intake resistance stays as low as new.

※1. Due to the thickness increase, the gap between the upper and lower frame may be too large to fit. If this is the case, push the frame in to install the filter.

Filter Structure Comparison

• A pleated type sports filter usually collects various sizes of dust on its surface; therefore, air passage becomes narrower which easily causes filter clogging even initial ventilation resistance is low.
• HKS Super Air Filter utilizes the density gradient structure where filter density becomes higher with each layer ensures all sizes of dust and other particles are caught gradually which maintains proper air passage resulting in a long product life.

Super Air Filter Replacement

Super Air Filter replacement. Easyily remove the old filter to replace the new one without changing the frame.
3 sizes (S, M and L) avaible for cutting.

Doesn’t require cutting

1. Remove Super Air Filter from a vehicle.

2. Disassemble Super Air Filter frame and dispose an old filter. In case if the frame uses metal clips, undo metal clips first, then proceed to removing the filter. Please be careful not to damage the frame.

3. Prepare a new filter by cutting a replacement filter material (this product), if necessary. (Details below)

4. Fit a prepared filter into the frame. Part with letters [○○○○-T] should be on the top of a coarse filter surface. Confirm that there are no gaps between the filter and frame sides.

5. Assemble the frame. In case if the frame uses metal clips, use metal clips to fixate the frame.

6. Install Super Air Filter Assembly into vehicle.
You may need to press on the assembly to fixate the frame when installing, as there might be a gap due to difference in thickness of the filter inside the frame in top and bottom part.

Instructions for Filter Cutting:

a. Lay old filter on top of the new filter material.

b. Trace edges of an old filter to draw a line for new filter with oil based ink pen.

Rough/Coarse Surface should face air inlet side, Finer surface should face engine side

c. Use drawn lines to cut out a new filter
