Many modern vehicles use a panel style air filter for cleaning the outside air your vehicle's engine breathes.

Panel filters are not the most robust of designs and when a vehicle is working under hot conditions (not uncommon here in Australia) the housing can slightly distort.

This ever so slight distortion can compromise the amount of clamping force it provides on the filter element allowing air to move past or around the filter rather than through it.

Dust or any fine particles can cause catastrophic damage to an engine. Even small quantities can significantly reduce its life span.

Its the same for oil and fuel filters as well as air.

Today's engines have sensors in the intake measuring things like airflow and/or pressure.

Dust collecting on these can cause faulty readings which can cause the engine's computer (ECU) to think there an actual fault - technically there is!

The vehicle may go into 'limp mode' in an attempt to prevent or minimise damage.

Not a great experience if you are a long way from home on a dusty dirt track.

A housing that holds barrel or drum type filter as found on heavy earth moving equipment provides much better clamping force to handle those more extreme conditions.

There are a number of reasons why barrel-style filters are not commonly used.

The complexity of modern engines does not provide much available space to install a larger barrel-style filter.

Cost is also a significant factor, generally panel filters are less expensive than barrel types.

So you have a panel type filter fitted and while you're doing a routine service you notice fine dust on the engine side (the 'clean' side) of the filter.

We know filters play a critical role in maintaining a healthy engine, even more, important for turbocharged vehicles - what should you do?

If you own a Toyota Land Cruiser 70 Series VDJ (V8 4.5L turbo diesel) or a Land Cruiser Prado 120/150 Series KZJ KDJ RZJ (4 Cyl 3.0L turbo diesel or 2.7L Petrol) we have a solution for you, the new air filter housing shim kit designed by Terrain Tamer.

• The kit includes a custom-designed shim along with a new Terrain Tamer branded air filter.
• It increases the clamping force the upper and lower sections of the air filter housing has on the filter element creating a more secure seal.
• All Terrain Tamer designed parts (including filters) are designed to meet or exceed OEM specifications.
• The shim itself is cut from approx 0.7mm stainless steel plate.
• It is designed to be installed into the sealing channel in the upper section of the housing.
• An adhesive like Sikaflex Pro is recommended to be used to secure the shim in place although it is not required.
