Product Details

The Bosch C3861WS cabin air filter features advanced multi-layer filtration technology designed to deliver superior air quality inside your vehicle. This premium carbon-activated filter provides maximum performance and durability while protecting against mold and mildew growth.

Three-Layer Filtration System:

  • First Layer: Non-woven pre-filter captures larger contaminant particles including dust, pollen, and debris
  • Second Layer: Electrostatically charged microfiber layer attracts and holds smaller particles down to microscopic sizes
  • Third Layer: Activated carbon layer absorbs odors, exhaust fumes, and harmful gases for fresher cabin air

Key Features:

  • Mold-resistant construction prevents bacterial and fungal growth
  • Carbon activation neutralizes unpleasant odors and airborne pollutants
  • High-efficiency filtration improves HVAC system performance
  • Direct-fit replacement for easy installation
  • Helps maintain optimal air conditioning and heating efficiency

Regular replacement of your cabin air filter ensures clean, healthy air circulation while protecting your vehicle's climate control system from premature wear. Bosch Workshop cabin air filters meet or exceed OEM specifications for reliable performance.

Great price, fair shipping.

Autoplicity had the tire brand and size I was seeking. The tires arrived after a 5 day Free Shipping period, from the opposite side of the United States. Installed the day of reciept and so far so good. The tires were fresh indicating proper storage facilities are in place even though they were manufactured in late 2017...great job overall. Thanks

Quality product at the best price found online, prompt delivery, well packaged.

Part as described. Priced ok...shipping a little slow.

We got what we needed quickly when other sites did not have the tires! Thanks.

It's smaller than it should be but said it fit my year/make/model for my Jeep

Not only did they have an great price on my part, and reasonable shipping charges, they shipped it right away.<br>I know I will be checking them for future parts.

Shopped around for a VDO gauge all over the internet incluing ebay, amazon and at least a dozen online retailers. Autoplicity was at least 10% cheaper than anybody else and a good 30% cheaper than most. The outstanding reviews made me more confident in ordering fom them for the first time.

I've had great service, quick shipment and awesome prices from Autoplicity. Definitely would recommend to anyone. I've placed multiple orders with them and everything is great!

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

Ordering was quick and easy. A lot of piece of mind being able to check out through Amazon. We'll see how the rest goes. (Shipment, correct product, customer service if needed, etc)

I purchased an Airaid throttle body spacer, they has they cheapest price on the web, no one else could even compare to the prices here at Autoplicity, I will definitely order from in the future!

The prices and selection are best. The cutomer service rep. did a good job in handling all my questions, and placed my order. I will be using Autoplicity for all my auto parts.

Best price I found and VERY fast shipping. Very happy.
