Dirty air filters can cause decreased fuel mileage, increased engine wear, and even problems starting the engine. Check your engine air filter at every oil change and always replace a dirty filter with a high-quality Bosch Workshop engine air filter to restore protection, performance, and efficiency. Bosch Workshop Air Filters are constructed with a high number of pleats for robust particle holding capacity, and deliver 98% filtration efficiency in removing small particles from incoming air to guard against engine wear. The high velocity cellulose cured media provides minimum air resistance and ensures even pleat distance for optimum efficiency. A high-quality polyurethane foam seal provides elasticity and sealing performance, while protecting against water and heat intrusion into the air intake system. All features combined ensure only the cleanest air for strong engine protection, high-performance, and better fuel efficiency.

Why Bosch?
High-Quality Seal
Our air filters are engineered with a polyurethane seal to safeguard the bypass of any unfiltered air. There is also no loss of filter surface through careful processing of the sealing material. It also reduces noise levels.
Enhance Your Vehicle
With superior filtration and sealing properties, Bosch engine air filters ensure only a clean supply of air reaches your engine, preventing premature wear caused by dirt and other abrasive particles, and ensuring optimal performance.
98% Filter Efficiency
The media is constructed with micropores, which provide a high-particle separation rate that in turn, protects a vehicle’s engine at a 98% efficiency* rate. It also prevents engine backfires from escaping the air intake system and possibly causing vehicle fires.

Fits right into place in my 2008 Toyota RAV4 (3rd generation). I needed to remove the rubber gasket in order for the airbox to seal and latch appropriately. Great buy and glad to purchase an affordable and reliable filter to keep my engine running. It is good quality

Used in my Lexus es350 and it fitted perfectly. Sealed up nice and snug and was easy to replace since it was used for it. Since it’s Bosch I know it’s quality. And performance felt great overall. Its value for money is also great. Overall great buy.

Better quality and fit than OEM (it has a rubber seal around the edge which my original filter didn’t have) , price was good too.

Fits my Toyota Avalon fine and airflow is good. Super easy to install and of course no smell. Only down fall is the black thick surrounding rubber makes it super hard to close the cap. Not sure if the rubber maker it a bit bigger or just not fitting full. As for value it’s really good price and let’s see if it last 6 months.

Dateline: A Garage, Under the Hood of a Toyota Venza, Sunday Night. Your engine is an angry, violent beast that lives on a diet of gasoline and air. And just like you, it cannot be breathing in the filthy, grit-choked air of the open road. It needs a filter. A gatekeeper for its lungs. A simple, pleated paper sentinel that stands between its sensitive guts and a world of dust, leaves, and suicidal insects.The old filter, a Denso original, came out looking like a sad, gray, choked-out relic. It had done its duty and was ready for a warrior’s burial in the bottom of a trash can. The replacement: a Bosch 5520WS Workshop Engine Air Filter, a name that promises German engineering at a working man’s price.Side-by-side with the outgoing OEM filter, the Bosch holds its own. The pleats are numerous, the frame is solid. The quality feels, for all intents and purposes, identical to the part that came from the factory. A good sign. This is no flimsy, cut-rate imposter.But there was a strange anomaly. A quirk in the design. The Bosch came adorned with an extra gasket, a rubbery lip that the original Denso lacked. A strange, superfluous addition. I stared at it, wondering if this was some advanced, new-world sealing technology or a simple manufacturing oversight. I could see where, in a different, less forgiving airbox, this extra gasket might put up a fight, refusing to seat properly. But in the accommodating plastic housing of the Venza, it settled in without a fuss. A strange choice, but not a fatal one.The installation itself is one of the last pure, simple acts of self-sufficient car maintenance left to the common man. You pop two metal clips, you lift the lid, you swap the filters, you snap the clips back down. It is a 60-second job, a glorious act of defiance against the quick-lube joints that would charge you a king’s ransom for the same trivial task.And the value is undeniable. You are getting a filter from a top-tier, reputable brand, with quality that is indistinguishable from the original factory part, for a price that leaves plenty of cash left over for life’s more important vices.So, despite the mystery of the extra gasket, the verdict is clear. The Bosch Workshop air filter is a solid, well-made, and absurdly affordable piece of essential hardware. It’s a smart buy for the savvy owner who isn’t afraid of a minor design quirk. The iron beast can breathe freely once more.
