Our tests have shown that the Predator 3500 Inverter Generator can benefit greatly from additional air flow into the generator's internal body. If you open the OEM oil door slightly, you can detect a significant vacuum drawing in outside air. Our vented Oil Filler Access Door has VENTS and a cleanable UniFilter™ brand air filter built in that allows air to flow with the following benefits....

1). Cooler running
We measured the exhaust temperature before and after and the difference was as much as 35 degrees Fahrenheit. That is a MAJOR difference and can extend the life of your generator.  This was from our test of our Predator 3500.   Your results may vary.

2). Prevent build up of dust, dirt and contaminants in the switches and outlets of the main control panel.
The vacuum inside your generator will be filled one way or another and right now, dirt and dust are being drawn through any small opening the air can find.
Our Replacement Oil Filler Access Door includes a cleanable, reusable Uni Filtertm that will protect your generator from dust and dirt.

3). Increased Fuel Efficiency
Because your generator can't breath, a vacuum is created at the intake. This causes additional fuel consumption. Our Vented Oil Door adjusts  that vacuum and let's your generator run at a more optimal mixture.

Note: Results can vary due to elevation, fuel used, usage of your generator and other factors.    We highly recommend you perform a spark plug check immediately after installing the Vented Oil Door to determine the approximate carburetion mixture of your generator.   Your spark plug should be a tan color.   A color closer to white could indicate a mixture that is too lean and can be harmful to your generator.  If the plug tip is dark colored it could indicate a rich mixture.  If you have questions feel free to contact us using the contact form on the web page.

if in doubt. AeroStarEngineering's sole remedy in case of claim shall be a full refund of your purchase price and we cannot accept any liability for any damage
to your generator. We accept no liability for any damages whatsoever and your purchase and use of this product is your agreement to these terms.
