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 Group with the Dopu  brands of filter guarantees OE quality which you can rely on.

Oil Filters

Oil filters are there to prevent engine wear and to maintain the quality of the oil over a long period of time. Oil filters must filter out from the oil all the dirt which would otherwise cause wear of the bearings. A good oil filter, which performs all the tasks required of it, only lasts a certain amount of time, after which it should be changed along with the engine oil.
