2. No Fuel Economy Improvement: While the AEM air intake kit can improve engine performance, it does not guarantee any fuel economy improvements. In fact, in some cases, it might even slightly decrease fuel economy due to increased engine demand.
3. Maintenance: The high-flow air filter in the AEM kit will need to be replaced more often than a standard air filter, which can add to the cost of ownership.
4. Voiding Warranty: Installing aftermarket parts like this air intake kit can void your car's warranty, so make sure to check your car's warranty terms before making a purchase.
Conclusion:The AEM 3.5L-V6 Air Intake Kit (07-11 Nissan Altima 21-499P) can provide significant performance improvements to your Altima, but it also comes with a high price tag and potential warranty issues. If you're a performance enthusiast and are willing to pay the price, this kit could be a great investment. However, if you're looking for a more budget-friendly option or are concerned about voiding your warranty, you might want to consider other aftermarket air intake kits.
Recommendation:If you're looking for a balanced approach, I would recommend considering the K&N 63-1242 Air Charge Air Intake Kit for the 2007-2011 Nissan Altima. It's a bit more affordable than the AEM kit, but still offers decent performance improvements and a good balance between cost and performance. However, as always, it's important to do your own research and consider your own needs and budget before making a purchase.
