You should have now completed your installation!!
Q. I have a Pontiac G8 GXP. Will your G8 V8 cold air intake system fit my car?
A. Yes, our G8 V8 CAI will fits perfect with no modifications.
Q. How often should I clean or replace my filter?
A. Some service as frequently as every third oil change. This is an easy way to keep track of maintenance intervals. Some go as long as every 20K or more if driving in clean conditions. You can look closely at the filter element and see a screen material-if the individual small squares look dirty or partially filled with dirt/debrs, its time to clean it.
If you do have an oil type filter (maroon in color) you can order a service kit directly from us or you can pick up a filter service kit at any parts store and save the shipping. If you have our dry filter (off-white in color) you can refer to the maintenance instructions below.
BTW, here is something often not considered by intake users-
As you drive the car the filter is constantly collecting dirt; therefore, it becomes restrictive in terms of air flow. A very small filter can make good power when it is brand new, but it goes downhill from there. It's one of the reasons we use such a large filter. As our filter starts to accumulate dirt the large amount of surface area we have becomes a big advantage because your car is still receiving the air it needs to perform well.
Dry Filter Cleaning/Maintenance Instructions
If you have our maroon (oil) filter-- DO NOT FOLLOW THESE INSTRUCTIONS!!!
Our filters are U.S.A. made and designed to last for the life of your car. Please follow these instructions for routine cleaning to maintain optimum performance.
Tap clean/85% clean:
You can tap your Pro Dry S filter and return it to 85% of its original airflow. Simply remove the filter from the intake kit and lightly tap it on a solid surface. Tap and turn the top and bottom of the filter until most of the visible dirt has been released. Reinstall the filter in your vehicle. Do not apply oil to the filter.
Vacuum clean/96% clean:
You can vacuum your Pro Dry S filter and return it to 96% of its original airflow. Remove the filter from the intake kit and vacuum away the dirt using a shop vacuum or regular house vacuum. Reinstall the filter in your vehicle. Do not apply oil to the filter.
Wash clean/100% clean:
You can wash your Pro Dry S filter and return it to 100% of its original airflow. Remove the filter from the intake kit. Run the filter under running water from the inside out. Turn the filter to remove all visible and hidden dirt. If your filter is coated with grease and road grime, it may be necessary to use soap and water to get it fully clean. You can completely submerge the filter in a mixture of warm water and mild detergent (use a common household detergent such as dish or liquid laundry soap) if needed. Rinse clean. Allow the filter to dry completely (our synthetic media dries quickly and should dry within a few hours in normal conditions). Reinstall the filter in your vehicle. Do not apply oil to the filter.
