Shop parts for a 2008 Suzuki DRZ70 Dirt Bike.

Proper air filter care is essential for reliable engine performance and long-term durability on the 2008 Suzuki DRZ70. A dirty or clogged air filter restricts airflow, reduces engine power, and increases the risk of dirt damaging internal engine components. This guide outlines proprietary MotoSport maintenance procedures tailored specifically to your DRZ70.

Why Clean & Replace the Air Filter?

  • Maximum protection: Dual-stage foam filters, like the OEM or Twin Air, use a coarse outer layer and fine inner foam to trap dirt, sand, and fine particles before they enter the engine. This is especially important for off-road riding conditions.
  • Improved engine performance: Clean filters help maintain unrestricted airflow for maximum power output and throttle response.
  • Simple maintenance: The DRZ70 makes filter access easy with a straightforward airbox cover and filter setup.

Unique Features of the 2008 DRZ70 Air Filter

  • Easy removal: Four Phillips screws hold the air filter cover. Unscrew them to access the filter.
  • Durable design: The filter is built for tough environments, with a fused dual-layer foam that resists clogging and withstands repeated cleaning cycles.
  • OEM-equivalent options: Filters such as Twin Air feature thick, greaseless sealing rings for maximum contact with the airbox, preventing leaks and ensuring proper filtration.

Step-by-Step Cleaning – Replacement Instructions

  1. Remove the air filter cover: Use a Phillips screwdriver to take out the four screws securing the plastic cover.
  2. Take out the filter: Gently pull the air filter from the airbox. Check for signs of heavy dirt, oily residue, or damage.
  3. Inspect the filter: For routine cleaning, inspect both foam layers. If either layer is torn, crumbling, or excessively dirty, replacement is recommended.
  4. Clean the filter: Rinse with a proprietary MotoSport-approved foam filter cleaner. Submerge completely, squeeze out dirt, repeat until fully clean. Do not wring or twist aggressively, as the foam can tear.
  5. Dry thoroughly: Allow the filter to air dry completely before oiling. Do not use heat or direct sunlight, as this can degrade the foam.
  6. Apply foam filter oil: Soak the filter evenly using a MotoSport foam filter oil. Massage the oil gently into both layers. Squeeze out excess–do not wring. A uniformly oiled filter traps fine dust efficiently.
  7. Reinstall with care: Add a thin layer of filter grease to the sealing ring, ensuring a perfect seal with the airbox. Reinsert the filter. Replace the cover and tighten the screws evenly to avoid pinching the foam.

Replacement Interval — Key Notes

  • Check the filter after every ride in dusty or sandy conditions.
  • Replace the air filter yearly, or whenever wear and damage develop. Replacement is quick–most owners consider upgrading to a dual-stage for maximum filtration.
  • A fresh filter costs little but prevents costly engine repairs–an essential routine for long DRZ70 engine life.

Additional Owner Tips for the 2008 DRZ70

  • Sealing ring: Check for cracks or flattening of the foam ring at each service. Imperfect seals lead to dirt bypassing the filter.
  • Airbox condition: Wipe out dust and debris from the airbox before reinstalling the filter to prevent contamination.
  • Do not run without a filter: Never operate the DRZ70 with the filter removedsevere engine damage can occur.

Staying ahead of maintenance keeps your DRZ70 running strong and ready for every ride. For OEM and performance air filter options, MotoSport delivers the right fit for your 2008 Suzuki DRZ70.
