Buying Guide
Choosing the right cold air intake for your 5.7 Hemi can feel overwhelming, but it doesn’t have to be. Here are a few key factors to consider:
- Performance Gains: Consider how much of a horsepower and torque increase you’re looking for. Higher-end intakes typically offer more significant gains, but they also come with a higher price tag.
- Budget: Determine how much you’re willing to spend. There are options available at various price points, so you can find one that fits your budget.
- Ease of Installation: Some intakes are easier to install than others. If you’re not comfortable working on your car, choose an intake that’s known for its simple installation process.
- Filter Type: Decide whether you prefer an oiled or dry air filter. Oiled filters require more maintenance but can offer better filtration. Dry filters are easier to clean but may not filter as well.
- Brand Reputation: Stick with reputable brands that have a proven track record of producing quality air intakes.
- Vehicle Compatibility: Make sure the intake you choose is specifically designed for your 5.7 Hemi. Check the manufacturer’s website or product description to confirm compatibility.
Don’t just look at peak horsepower numbers. Consider the entire power curve. A good intake will improve power throughout the RPM range, not just at the very top end.
FAQs
Will a cold air intake void my warranty?
It depends. A cold air intake *could* void your warranty if it’s proven that the intake directly caused a failure. However, the manufacturer has to prove that the aftermarket part caused the issue. The best practice is to stick with reputable brands and understand your warranty terms.
How much horsepower will a cold air intake add to my 5.7 Hemi?
Gains vary, but you can typically expect to see an increase of 10-20 horsepower with a good cold air intake. Other factors, like exhaust and tuning, can also affect the overall power gains.
Do I need to tune my car after installing a cold air intake?
Some intakes may require a tune to optimize performance. Check the manufacturer’s recommendations. If you notice any issues after installation, like poor idle or hesitation, a tune may be necessary.
How often should I clean my air filter?
Cleaning frequency depends on driving conditions. Generally, you should clean your filter every 25,000 to 50,000 miles, or more often if you drive in dusty or dirty environments. Oiled filters need to be re-oiled after cleaning.
Conclusion
Upgrading to a cold air intake is a great way to boost the performance and sound of your 5.7 Hemi. Whether you’re looking for maximum power gains, a factory-backed option, or a budget-friendly solution, there’s an intake on this list that’s right for you. Take the time to research your options, consider your budget and needs, and choose an intake that will deliver the performance and reliability you’re looking for. Happy driving!
