The task of the air filter

  • To protect the engine against dirt particles in the intake of air
  • To protect the engine against wear
  • To safeguard the air supply in the mixture generation
  • To reduce the noise level

Change the air filter regularly according to the vehicle manufacturer's specification.

The consequences of a dirty filter:

  • Poor air-fuel mixture generation resulting in reduced engine power and increased pollutant emissions
  • Increased fuel consumption
  • Increased engine wear from particles
  • Problems starting your vehicle

The prerequisite for flawless operation: A tight fit

Leakages and porosity lead to a bypass of unfiltered, unmetered air into the intake duct. Consequently, Bosch air filters are made with a longer-lasting seal made of polyurethane:

  • Exact fit matched to the housing shapes
  • Unevenness in the housing is compensated for
  • Flexibility and suppleness in the seal across the entire service life of the filter

  • Bosch is one of the world's leading manufacturers of gasoline and diesel systems, so no one is better placed to specify the right filter than Bosch
  • Each filter is made specifically for each engine type, so they are matched to the specific engine requirements without compromise
  • Guaranteed standards that meet or exceed vehicle manufacturer specifications
  • Improved engine performance and fuel consumption
  • Increased service life and reduced engine repairs

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.

How long will it take to get my order?

We give an estimate of delivery dates as you shop and in your basket. The vast majority of items are held in stock and dispatched from our UK warehouse and we'll do all we can to get your order to you as quickly as possible.
