For the best off road experiences, it's crucial that you ensure the air your engine is breathing is as cool and dense as possible, which will optimise the air to deliver effective combustion of your fuel. The cooler your engine is, the more power it will give you... and intercooler spacers will help a lot.
The cooler your engine is, the power you'll have at your disposal, it's that simple. Intercooler spacers reduce or completely get rid of the heat generated by your engine, by fully containing the airflow between the bonnet scoop and the intercooler.
If you install a body lift kit to your vehicle with a top mount intercooler and bonnet scoop, the bonnet scoop is raised 50mm with the body. The result is that the air stream passing through the intercooler is no longer contained so the engine's cooling will be negatively affected.
There a number of fixes, but by far the best action to take is installing an intercooler spacer which captures the air stream within the bonnet scoop's internal rubber boot. If you live in a cooler part of Australia you might not have to take this action...
...but if you reside and drive around the hotter places or tropical regions it's an absolute must. And when you do, you should also try installing a slimline intercooler fan to the flange along with a high end intercooler spacer - there are often mounting holes provided to do this.
An top mount intercooler fan comes in very handy on your vehicle to remove the heat soak which can gather on top of the engine if driving at low speeds off road. Because under these conditions there is not enough air flow through the bonnet scoop to cool the incoming air, which can bring about reduced oxygen, low quality combustion, poorer performance, higher exhaust temperatures and increased risk of engine failure.
Having an intercooler fan with your intercooler spacer look really cool, and it's a look that is only possible to achieve with a body lift... because if you don't have a body lift there is not enough room between the intercooler and the bonnet to fit one!
