The upper filter housing of some 4WDs features a seal surface too narrow to match the seal of the filter itself. As a result, the filter is not able to be fully effective, allowing dust to pass through the airbox and enter the engine intake, causing havoc with components.
In response, Terrain Tamer designed a range of vehicle specific, stainless-steel filter inserts for the most problematic vehicle models, which, when fitted, create a surface area that perfectly matches the filter, aligning in the correct position to properly seal, and reducing the issue of dusting. +
This problem is particularly prevalent in 4WD’s where gravel roads, bull dust and sand all contain damaging particles, and the original airbox design only compounds this.
While it’s good practice to remove the air filter on a regular basis, and clean it or replace it, for vehicles doing a lot of work offroad, the filter will not last the service interval.
Essentially an airbox filter insert upgrade, the simple innovation holds the airbox structure, greatly reducing the risk of engine damage from dust particles.
Sold in kits, which also include the corresponding Terrain Tamer Air Filter, as well as sealant required, making it a quick, simple and whole solution for workshops or home mechanics to fit without needing to source anything extra.
