Bosch Workshop Cabin Air Filters capture up to 99% of dirt and other environmental particles over 3 microns (up to 80% of particles under 3 microns), preventing them from entering the passenger cabin, which results in a noticeable improvement in air quality.
Exact Fitment for Acura & Honda Sedans
The P3600WS is manufactured to Bosch’s strict OEM dimensional standards, ensuring perfect fitment and easy installation inside the factory HVAC housing. No trimming. No complaints. No fuss.
Acura Fitment
Acura CL (2001–2003)
✔ Fits 3.2L V6 models
These CL models use a compact HVAC system that benefits significantly from clean airflow. A fresh Bosch filter helps eliminate interior dust and restores efficient A/C performance.
Acura TL (1999–2003)
✔ Fits 2.7L and 3.2L V6 models
A dirty cabin filter in these early TL models leads to slow defrosting and weaker cooling output. The P3600WS solves those issues quickly by restoring full airflow volume.
Honda Fitment
Honda Accord (1998–2002)
✔ Fits 4-cylinder and V6 engines
One of the most common symptoms of a clogged cabin filter on these Accords is persistent musty odors and reduced blower output. Replacing it with a Bosch Workshop filter immediately improves both air quality and HVAC efficiency.
Performance and durability are maximized by multi-layer media. 1st Layer – Larger particles are captured by the non-woven pre-filter layer. 2nd Layer – Elusive smaller particles are attracted and held by the electrostatically charged microfiber layer. 3rd Layer – Non-woven cover layer adds stability to protect the microfiber layer from damage and acts as an additional barrier to harmful elements.
When Should You Replace Your Cabin Air Filter?
Honda and Acura models of this era should have their cabin filters replaced every 12,000–15,000 miles, or sooner if you notice:
-
Musty or stale interior smells
-
Weak airflow from vents
-
Difficulty defrosting windows
-
Excessive dust inside the cabin
A fresh Bosch filter is one of the easiest ways to improve interior comfort without touching a wrench anywhere else on the vehicle.
Bosch Workshop Cabin Air Filters feature high pleat counts that provide greater surface area for higher filtration capacity. Foam perimeter gasket (select part numbers where specified by OE) prevents harmful particles from bypassing the filter media. Rigid frame (select part numbers where specified by OE) adds stability for peak performance and long service life.

Good quality. Fits well. Hard to install, but that is due to the vehicle design. Best value filter I could find to keep the air cleaner in the car.

I was at first hesitant because I thought I would receive the wrong item but in the end I was wrong and got the exact item. It also comes in a wrap bag which keeps the Cabin Air Filter fresh. Not a lot of wrap up their cabin air filters in bags. Love the quality they went here for a $14 aftermarket cabin air filter. Bosch is the best most of the time the best 👍 Made my AC work way better on my 2001 Honda Accord EX

Installed in a 2001 Honda Accord that looked like it had factory filters installed. Hard to change in an Accord but the difference in air quality is amazing and worth it.
