Why Choose K&N Drop-In Filters?

- Increased Airflow: K&N filters allow more air to flow into the engine, which can improve combustion efficiency.
- Reusable: These filters are washable and reusable, making them a cost-effective choice over time.
- Easy Installation: Drop-in filters are designed to fit directly into your factory airbox.
Tools and Materials Needed
Before starting the installation, ensure you have the following tools and materials:
- New K&N drop-in filter (specific to Lexus IS300)
- Flathead screwdriver
- Phillips screwdriver
- Socket wrench set
- Shop towels or rags
Step-by-Step Installation Guide
Step 1: Prepare Your Vehicle
Park your Lexus IS300 on a flat surface and turn off the engine. Allow it to cool down to prevent burns during installation.
Step 2: Open the Hood
Using the hood release lever inside your vehicle, open the hood and secure it with the prop rod.
Step 3: Remove the Airbox Cover
Locate the airbox on the driver’s side of the engine bay. Use the appropriate screwdriver or socket wrench to remove the screws or bolts securing the airbox cover. Carefully lift the cover off to expose the air filter.
Step 4: Remove the Old Air Filter
Take out the old air filter from the airbox. Be cautious of any debris that may fall into the airbox during removal. Dispose of the old filter properly.
Step 5: Clean the Airbox
Use a shop towel or rag to clean any dust or debris from the inside of the airbox. This ensures a clean environment for the new filter.
Step 6: Install the K&N Drop-In Filter
Place the new K&N drop-in filter into the airbox, ensuring it fits snugly into place. Make sure the rubber sealing edge is properly seated to prevent unfiltered air from entering the engine.
Step 7: Reattach the Airbox Cover
Carefully place the airbox cover back on and secure it with the screws or bolts you removed earlier. Ensure everything is tightened properly to avoid any air leaks.
Step 8: Close the Hood
Once everything is reassembled, close the hood securely. Make sure it is latched properly before starting the engine.
