Upgrade Your Hemi: The Ultimate Cold Air Intake Buying Guide
So, you’ve got a 5.7 Hemi engine and you’re looking to give it a little more pep. A cold air intake might be just the ticket! This guide will help you pick the best one for your ride.
What is a Cold Air Intake?
A cold air intake replaces your car’s stock air intake system. It lets your engine breathe in cooler, denser air. Cooler air has more oxygen. More oxygen helps your engine burn fuel better. This can lead to more horsepower and better fuel economy.
Key Features to Look For
When you’re shopping for a cold air intake, keep these important features in mind.
1. Air Filter Type
- **Washable/Reusable Filters:** These are a great long-term investment. You can clean them and use them again. They often use materials like cotton gauze or synthetic fibers.
- **Disposable Filters:** These are cheaper upfront but you’ll need to buy new ones regularly.
2. Intake Tube Material
- **Polished Aluminum:** Looks shiny and cool. It’s also strong and lightweight.
- **Carbon Fiber:** Very lightweight and strong. It also adds a high-performance look.
- **Plastic:** Cheaper but might not look as good or last as long.
3. Heat Shield Design
A good heat shield blocks hot air from the engine. This keeps the air going into your engine as cold as possible. Look for a shield that fits snugly around the filter.
4. Ease of Installation
Some kits are designed for easy DIY installation. Others might need more tools or expertise. Check reviews for how difficult the installation process is.
Important Materials
The materials used in your cold air intake matter.
- **High-Flow Air Filter:** Usually made of layered cotton gauze or synthetic media. This lets more air through than a stock filter.
- **Durable Tubing:** Aluminum, carbon fiber, or high-quality plastic. This tubing guides the air to your engine.
- **Robust Heat Shield:** Often made of plastic or metal. It protects the filter from engine heat.
Factors That Improve or Reduce Quality
Several things can make a cold air intake better or worse.
Improving Quality:
- **Proper Fitment:** The intake should be designed specifically for your 5.7 Hemi. A good fit means better airflow and easier installation.
- **Smooth Internal Surfaces:** A smooth intake tube helps air move faster.
- **Quality Seals:** Good seals prevent hot air from leaking into the intake.
Reducing Quality:
- **Poor Fitment:** If it doesn’t fit right, it won’t work as well.
- **Sharp Bends in Tubing:** These can slow down airflow.
- **Cheap Materials:** Low-quality materials might break down over time.
User Experience and Use Cases
Most users report a noticeable improvement in throttle response. The engine often sounds more aggressive, too. People use cold air intakes for:
- **Daily Driving:** To get a little better gas mileage and a more responsive feel.
- **Performance Driving:** For that extra horsepower boost when you need it.
- **Towing:** The improved airflow can help your engine work a bit easier.
Frequently Asked Questions (FAQ)
Q: Will a cold air intake void my car’s warranty?
A: It’s possible. Some manufacturers might say it voids the warranty for engine-related issues. Check your warranty details.
Q: How much horsepower can I expect to gain?
A: Gains vary, but you might see anywhere from 5 to 20 horsepower. It depends on the intake and your specific vehicle.
Q: Is a cold air intake difficult to install?
A: Most are designed for DIY installation. Some kits are easier than others. Look for kits with clear instructions.
Q: Will it change the sound of my engine?
A: Yes, it often makes the engine sound deeper and more aggressive, especially under acceleration.
Q: Do I need to tune my car after installing a cold air intake?
A: For most 5.7 Hemi applications, a tune is not strictly required for basic cold air intakes. However, a tune can help you get the most out of the intake and other modifications.
Q: How often do I need to clean or replace the air filter?
A: Washable filters need cleaning every 15,000-30,000 miles. Disposable filters need replacement as recommended by the manufacturer.
Q: Can a cold air intake improve my fuel economy?
A: Some users report slight improvements in fuel economy. This is because the engine can breathe more efficiently.
Q: What is the difference between a short ram and a true cold air intake?
A: A true cold air intake relocates the filter outside the engine bay to draw in cooler air. A short ram intake keeps the filter within the engine bay, so it might not be as cold.
Q: Are there any downsides to a cold air intake?
A: Some intakes can suck up water if you drive through deep puddles, potentially causing engine damage. This is less common with well-designed systems with heat shields.
Q: Where is the best place to buy a cold air intake for my 5.7 Hemi?
A: Reputable online auto parts retailers and specialized performance shops are good places to look. Always ensure the kit is listed for your specific vehicle year and model.
