FAQs—GMC Cold Air Intake
- Is it true that the check engine light can be triggered by a cold air intake system?
This depends on the aftermarket air intake system that you'll install on your vehicle. Quality air intakes, those offered by trusted brands or well-known aftermarket manufacturers, are built to work specifically with the vehicle, not mess up any system. So when these are installed, these won't activate the check engine light or trigger the fault codes. They're not designed this way. Instead, they offer some performance gains or improvements. Low-quality or substandard air intake systems may, however, cause some problems. They may fit but may not exactly ensure peak engine performance without due consideration to air-fuel ratios and other settings that may affect how the engine runs. These intake systems are not street legal.
- Are aftermarket intake systems illegal in California?
If the aftermarket intake system or part isn't CARB-certified or -approved, this is not street legal in California. You may fail the smog test or inspection because of this. Look for cold air intake systems or aftermarket upgrades that are legal in all 50 states or ones that comply with the requirements. These intake systems are rigorously tested ton ensure proper fitment and premium performance.
- If a cold air intake system is installed on my GMC vehicle, will this void may manufacturer warranty?
Performance upgrades won't automatically void or cancel out the warranty of your vehicle. Under federal law, the Magnuson-Moss Warranty Act, the car owner can't be denied the warranty service or coverage if the aftermarket part didn't cause the defect or isn't at fault in causing the damage or failure of a specific part or system. Improper installation of the performance part or the deficiencies of the system, though, can be cited for denied the warranty service if this is proven to have caused the damage or breakage. So if a performance mod will be installed, look for a quality option or a product from a trusted manufacturer.
- Is it difficult to install a cold air intake system?
The level of difficulty in installing a performance air intake system may vary for each vehicle. But generally, air intake systems can be installed using basic hand tools and within minutes. Detailed instructions are usually provided by the manufacturer. Most are designed for straightforward installation.
- What are the benefits and downsides to using a GMC cold air intake system?
Basically, the cold air intake is designed to bring in colder air into the engine. Cold air is denser, which means that more air is fed into the engine, making it easier to generate power. This may translate to increased horsepower. This air intake system can also promote better fuel efficiency. By putting less stress to the engine, it won't be consuming more fuel in the process. This improves engine efficiency. It can also prevent overheating and damage since the engine is able to run at lower temperatures. In effect, this can keep the engine in better working condition and can extend its life.
There are also some concerns about the use of the cold air intake system such as the risk of ice forming inside the air intake system during the cold season and fuel droplets failing to evaporate properly. Some manufacturers have addressed these issues, though.
