Frequently Asked Questions

Will your Airbox fit with plastic snorkels?

Yes, the majority of our air boxes have been developed to connect to a plastic snorkel as well as Stainless steel snorkels. Although the airbox can be connected to a plastic snorkel most plastic snorkels are poorly sealed or unable to be fully watertight sealed at connection points.

We recommend using a stainless steel snorkel when a watertight intake system is required.

Will my vehicle need tuning after fitting one of your products?

No, tuning is not a necessity when upgrading the intake of your vehicle however, tuning can unleash additional power. When installing performance intake upgrades the vehicle has a greater potential for higher air density going into the motor.

The higher density air will increase the potential for power to be increased safely while maintaining safe combustion temperatures.
Without tuning the benefits of an intake system will be better efficiency, lower EGT Temperatures, improved economy, reduced heat soak power loss.
With the benefits of tuning Power can be increased while still maintaining safe engine parameters .

How do I Choose which Filter will best suit my needs?

When choosing your filter, we recommend using our Offroad filter if you plan on taking your vehicle into dusty situations.
These may include things like farm work, driving in convoy off-road, driving in dry dusty conditions etc.

The offroad filter will give your engine the best possible protection against dust ingress while still providing great flow properties.
If you do predominantly on-road driving with the occasional offroad adventure then our hi flow may be able to offer some additional flow.
The hi flow filter provides great filtration for larger particles 5 microns and above while still allowing the maximum flow. Suited to on road and off-road conditions where dust is minimal. Beach, mud etc.

Whats included in a kit?

All PSICO Performance kits come complete with instructions, templates, and all quality components required to install the component. You just supply the time and tools.

Are your Airboxes fully sealed?

Yes, our air boxes are designed to create a fully sealed water tight intake system. Our air boxes run an o’ringed port bung on air boxes that are easily accessible.
On air boxes that are in hard to access areas we run a hose to an easy to access location making it simple and easy to monitor and drain any water if necessary.
Some customers opt to leave there air box bung out to drain auto and install only when necessary. In order to ensure your intake system is fully sealed we recommend testing at install and regular intervals.
Note in order to have an entirely sealed intake system requires using suitable snorkel and components combined.

How long will it take me to fit a product?

Most of our products can be easily installed in 2-3hrs.

Are your products Flow Tested?

Yes, we flow test all of our products and ensure that every product we make significantly increases the intake flow and efficiency.
