You'll often find that cheap filters are more expensive in the end!

There are often amazing special offers for air filters, oil filters and fuel filters. If you snap one up, you'll certainly save a few pounds. Unfortunately, the only savings you make will be on the purchase price!

For in practice, cheap offers can suddenly become all too expensive. Often, a deceivingly similar exterior will conceal a low-quality interior which does the engine more harm than good. There are plenty of good reasons why filters have to pass the toughest tests before being released as original equipment, in the test laboratories of development partners as well as international engine and vehicle manufacturers.

When purchasing your filter, always look for products of known OE quality. The DOPU Filter Systems Group with the DOPU brands of filter guarantees OE quality which you can rely on.
