Mazda B2500 Turbo Air filter

Try putting grease on the sealing parts of the air filter.
If it is going through the filter try a Finer filter.

Try putting grease around the sealing areas...
Works on motor bikes.Or buy a finner filter .

The first thing I tried was the grease on the sealing rubbers.
The dust passes through the element.
Anybody know about the replacement air box from Mazda ?

go the finer filter helps with power and fuel economy as well and is reusable for the life of the vehicle. Col

COLIN SAID. . . Finer filters are the ultimate crap, messy, sticky. If you are using a genuine air filter element or a Ryco element there is no reason why you should see dust on the other side of the air filter element. I would suggest there may be a design flaw in the air filter element housing as that is one of the few things they have changed in the later model.

Spot on colin !! They have a problem with a badly designed air box that is to small. Some dealers in country areas are replacing the box under warranty ...about $800 parts. I am interested to see if anybody has had the thing changed under warranty
If a paper element wont stop dust. . . .wait for it. . .. there is no way a bit of pourous oiley sponge will do the same job.
Finer filters are for saving money . . . but when you spend $40k $50k on a vehicle the cost of a $25 filer should not come into the isue.
Now haveing said that, I dont want to spend $800 on parts to replace parts that were badly designed.

Wow this should get the aftermarket buyers going.
Looking forward to repys
