Pajero Owners Club of South Africa

I did a bit of filter changes to the new baby over the week-end and realised that the poor thing must have a serious breathing problem through that air filter configuration. I then remembered that on the 4x4 Community Forum a forumire called DVR did a series on improving the fuel consumption of a 2500 Mazda diesel bakkie. First thing he suggested was to abandon the monster air filter and replace it with an "open" breathing system. Would it not be a good dea if I did the same thing. Surely the breathing principle for all (? ) diesel engines is the same ? Was just wondering - maybe one of those big shiny fancy cone type filters.He claimed to be able to improve fuel consumption quite dramatically, albeit together with some additional mods.

SQ,

The benefit of clean air into your motor has to be weighed up against the restriction caused by cleaning it. I have no doubt that one could get better flow by reducing the filtration.

There is a thread here where we discussed removal of the "cyclone fins" in the Gen3 and 4 Pajeros. Ideally we should have a filtration system for each applications based on expected dust conditions. The same goes for the cooling system, tank size, legroom vs boot space etc.

The manufacturers normally go for a low maintanance system that offers the best protection.
