The Ultimate Guide to AFM Delete Kits
Active Fuel Management (AFM) systems often cause engine trouble in modern vehicles. These systems shut down cylinders to save fuel. Over time, this can lead to lifter failure and oil consumption. An AFM delete kit removes these parts to make your engine more reliable. This guide helps you choose the right kit for your vehicle.
Key Features to Look For
When shopping for a kit, look for complete sets. A good kit includes new lifters, a valley cover, and head gaskets. Some kits include a camshaft upgrade. If you want more power, look for a kit that includes a performance cam. Always check if the kit comes with new head bolts. You should never reuse old head bolts during this process.
Important Materials
Quality matters when working inside your engine. Look for hardened steel lifters. These parts handle high heat and constant movement. Avoid cheap plastic or soft metal components. The valley cover should be made of high-grade aluminum. This ensures a tight seal and prevents oil leaks. High-quality gaskets are also vital for keeping coolant and oil in the right places.
Factors That Improve or Reduce Quality
What improves quality?
- Using OEM (Original Equipment Manufacturer) parts.
- Choosing kits that include complete hardware sets.
- Buying from reputable brands with long track records.
What reduces quality?
- Using generic, unbranded parts.
- Missing seals or O-rings in the package.
- Poor machine work on the valley cover surface.
User Experience and Use Cases
Most users install these kits to fix a ticking noise in their engine. This noise often signals a failing lifter. After installing the kit, the engine runs smoother. You might notice a small drop in fuel economy, but the engine reliability increases greatly. This upgrade is best for owners who plan to keep their vehicle for a long time. It is a major job, so it is perfect for those who enjoy working on their own cars.
Frequently Asked Questions
Q: Is an AFM delete kit hard to install?
A: Yes, it is a big job. You must remove the cylinder heads to change the lifters. If you are not an experienced mechanic, consider professional help.
Q: Will this void my warranty?
A: Yes, modifying the internal engine components usually voids the factory warranty.
Q: Do I need a computer tune after the install?
A: Yes. You must turn off the AFM software in the engine computer. If you do not, the engine will run poorly.
Q: Does this make my engine louder?
A: Not really. You might notice a slight change in exhaust tone, but it will not be very loud.
Q: Can I drive the car before the computer tune?
A: It is not recommended. The engine will likely run with a “Check Engine” light and may misfire.
Q: Does this improve horsepower?
A: The kit itself just fixes the system. However, if you add a performance camshaft, you will see a big jump in power.
Q: How long does the install take?
A: For a skilled mechanic, it takes about 10 to 15 hours of work.
Q: Is oil consumption reduced after the install?
A: Many users report that oil burning stops once the AFM system is removed.
Q: Should I change my oil after the install?
A: Yes, always perform a fresh oil change immediately after finishing the installation.
Q: Are these kits street-legal?
A: Yes, they do not change your emissions equipment, so they remain street-legal in most areas.
