Filters in Mazda 3

Filters in Mazda 3.

It is best to use original filters dedicated by Mazda. Due to the lack of original filters, we recommend companies: knecht, purflux, mann, our friend Jaksa also talks about the Japanese MAXX. From the air filter (quality) depends on the noise level and engine efficiency. The durability of the pump depends on the fuel filter. Engine wear depends on the oil filter… Filters really have a job to do and that shouldn't be underestimated.

With poor oils and filters, camshafts may wear out (and not only in Mazdas) especially on the first bridge…

More and more often under the hood of DiTD (and newer CR) Unfortunately, you can find an air filter for a two-liter petrol engine, not a diesel one – which clearly affects the power and strength of the motor!! Filter “petrol” it has folds of filtering fabric every 6-12 mm, in the diesel version they are every 2-3mm. Personally, I recommend the Knecht LX filter 936 and oil OC205 (and there is the same set for DiTD and CD).
