Aftermarket air filters: new 4x4 products

WANT to optimise performance? These 4x4 aftermarket filters will do the trick.

ITGA performance air filter

ITGA has drawn on its extensive motorsport past to produce this new performance air filter for the Ford Ranger PX-I and PX-II and its Mazda BT-50 twin (2011-2018), covering the three engine options for those vehicles (2.2L, 2.5L, 3.2L).

The washable/reusable filter comes pre-oiled for an easy install and is claimed to improve throttle response, fuel economy and power outputs when compared to the OE filter.

The drop-in design uses a tri-foam system (reticulated polyester foam) that ITGA says offers better performance in terms of optimising airflow, cleaning efficiency (can block high volumes of airborne dust while keeping the engine fed with clean air), and can absorb large amounts of dust without affecting its air-flow capacity.

Unifilter panel filters

Dust ingestion issues are becoming a big problem with a number of popular 4x4s, such as the LandCruiser (70 Series and 200 Series), Prado 150 Series, HiLux, Nissan’s D40 and D23 Navara, the Mitsubishi Triton and the Isuzu D-Max.

The sealing edge of the OE filters are the culprit due to using rubber seals on plastic, where each material reacts to heat in a different way and the resultant warping creating a gap between the edges and allowing dust in.

Unifilter’s foam seal resolves the dust ingress issue on Toyota’s Cruiser and Prado, with this seal added to the sealing edge of the rubber seal; the sealing edge of the OE Toyota filters is flat, so Unifilter has added a foam seal that doesn’t breathe so dust will not penetrate.

The second type of panel filter (used in other manufacturers’ vehicles) uses a step style seal; Unifilter has widened the edge of its filter to make it flat (as opposed to a point), thus spreading the sealing point. These replacement filters are also ridged to stop deformation under load.
