Bosch oil filters are OEM and aftermarket filters made by the German parts manufacturer Bosch, sold under the Bosch brand and through retailers including Amazon, AutoZone, Walmart, and Advance Auto Parts
Bosch manufactures oil filters for most vehicle makes and model years, both as original equipment (the filters that come in new cars from the factory) and as replacement filters you can buy separately. The company produces filters for passenger cars, trucks, and SUVs across domestic and foreign brands. Bosch filters are not exclusive to any single manufacturer — you will find them sold at national auto parts chains, online retailers, and some dealerships.
A Bosch oil filter works the same way any oil filter does: it removes contaminants from engine oil as the oil circulates. The filter sits in the engine bay, usually on the side or bottom of the engine block, and the oil passes through it under pressure. When you change your oil, you replace the filter cartridge or the entire filter housing, depending on your vehicle's design.
Key Takeaways
- Bosch makes both original equipment filters (installed at the factory) and aftermarket replacement filters sold at auto parts retailers and online.
- You need your vehicle's year, make, model, and engine size to find the correct Bosch filter part number for your car.
- Bosch filters are priced in the mid-range for replacement filters, typically between $8 and $20 depending on the model.
- The filter part number is printed on the canister itself, so you can match it to your old filter when shopping for a replacement.
How to identify the correct Bosch filter for your vehicle
The most direct way is to look at the filter currently in your engine. The part number is printed on the outside of the canister. Write down that number and search for it at any auto parts retailer — the result will be the correct replacement. If you do not have the old filter in front of you, use your vehicle's year, make, model, and engine displacement (usually listed in your owner's manual or on a sticker inside the driver's door jamb) to search Bosch's parts finder or a retailer's filter lookup tool.
Bosch publishes a cross-reference guide on its website that lists filters by vehicle process. You enter your vehicle information and the tool returns the correct part number. AutoZone, Advance Auto Parts, and Walmart all have similar lookup tools on their websites. If you are unsure about any detail, call the parts counter at a local auto parts store with your vehicle's VIN (vehicle identification number) — they can look up the correct filter in seconds.
Bosch filter types and what they filter
Bosch makes several filter lines for different vehicle types and maintenance needs. The most common is the standard spin-on filter, a cylindrical canister that screws onto a threaded port on the engine. Some vehicles use cartridge-style filters, which are flat or cylindrical elements that sit inside a housing on top of the engine — you replace the element but not the housing itself.
All Bosch oil filters contain a pleated paper media (the material that actually traps particles) and a bypass valve. The bypass valve opens if the filter becomes too clogged, allowing oil to flow around the filter to prevent engine starvation. The media is designed to trap particles down to a certain micron size — typically 10 to 25 microns for standard filters. Bosch does not publish a single "micron rating" across all its filters because the rating depends on the specific filter model and your vehicle's engine design.
Where to buy Bosch oil filters and typical pricing
Bosch filters are widely available at national chains including AutoZone, Advance Auto Parts, O'Reilly Auto Parts, Walmart, Target, and Amazon. Dealerships also stock them, though often at a higher price than independent retailers. Prices vary by filter model and retailer, but a typical Bosch replacement filter costs between $8 and $20. Spin-on filters are usually on the lower end of that range; cartridge-style filters may cost more depending on the housing design.
Online retailers often offer lower prices than in-store, but you will need to wait for shipping. If you need the filter today, a local auto parts store is faster. Some retailers offer free in-store pickup if you order online, which combines the speed of a local store with the price of online shopping. Check whether the retailer offers a core exchange — some will credit you $3 to $5 if you return the old filter, which lowers your net cost.
Bosch filters versus other brands
Bosch competes with Fram, Mobil 1, Purolator, and store-brand filters sold by retailers. Bosch filters are generally considered mid-range in quality and price — not the cheapest option, but not premium-priced either. The main difference between brands is the media quality, bypass valve design, and the size of the filter canister. A larger canister can hold more dirt before it clogs, which means the filter lasts longer between oil changes.
If your vehicle originally came with a Bosch filter from the factory, using a Bosch replacement is a straightforward choice — you know the filter was designed for your engine. If you are switching from another brand, the difference in performance is usually small enough that you will not notice it during normal driving. The more important factor is changing the filter on schedule, regardless of brand.
What happens during an oil filter change
An oil filter change is part of a routine oil change. The old filter is unscrewed or unbolted from the engine, the new filter is installed, and the engine is started to circulate fresh oil through the new filter. For spin-on filters, you hand-tighten the new filter until the rubber gasket on the filter base contacts the mounting surface, then turn it an additional three-quarter turn. Over-tightening can damage the gasket and cause leaks.
For cartridge-style filters, you remove the housing cap (usually with a wrench), pull out the old element, install the new element, and replace the cap. Some cartridge housings require a new rubber seal or O-ring each time you change the filter — check your owner's manual or the filter packaging to see whether a seal is included. After installation, start the engine and let it idle for a minute to prime the new filter with oil, then check the oil level and top up if needed.
How often to replace a Bosch oil filter
Most manufacturers recommend replacing the oil filter every time you change the oil. Oil change intervals vary by vehicle and driving conditions — some newer cars go 10,000 miles between changes, while others go 5,000 miles or less. Check your owner's manual for the interval specific to your vehicle. If you drive in severe conditions (frequent short trips, towing, dusty environments), your manufacturer may recommend more frequent changes.
The filter should never go longer than the oil change interval. Using the same filter for two oil changes is not recommended because the filter media becomes saturated and the bypass valve may open, allowing unfiltered oil to circulate. Replacing the filter at every oil change is inexpensive insurance against engine wear.
Frequently Asked Questions
How do I know if a Bosch filter will fit my car?
Use your vehicle's year, make, model, and engine size to search the Bosch parts finder or any auto parts retailer's lookup tool. If the tool returns a Bosch part number, that filter is designed for your vehicle. You can also match the part number on your current filter to confirm the replacement.
Can I use a Bosch filter if my car originally came with a different brand?
Yes. As long as the Bosch filter part number matches your vehicle's process, it will fit and function correctly. Many owners switch brands at replacement without any issues. The key is matching the part number to your vehicle, not the brand name.
What is the difference between a Bosch spin-on filter and a cartridge filter?
A spin-on filter screws directly onto the engine and is replaced as a complete unit. A cartridge filter is an element that sits inside a housing on the engine — you replace only the element, not the housing. Your vehicle uses one or the other based on its engine design. Check your owner's manual or the current filter to see which type yours has.
Do I need to drain oil before removing the old filter?
For a spin-on filter, some oil will spill when you unscrew it, but you do not need to drain the entire oil pan first. For a cartridge filter, you may lose a small amount of oil when you remove the housing cap. Have a drain pan or old towels ready to catch spills. The oil lost during filter replacement is minimal compared to a full oil change.
Where should I dispose of the old oil filter?
Most auto parts retailers accept used oil filters for free, and many will credit you a small amount if you bring in the old filter. Some recycling centers and municipal hazardous waste facilities also accept filters. Never throw an oil filter in the trash — the oil inside is an environmental contaminant.
