What to Consider for Long Life of Cold Air Intake – Expert Tips

A cold air filter is the best car upgrade that will boost horsepower, performance, and efficiency of your engine. These tips help you before purchasing the product.

1. Dry or Oil Filter
They are both great. dry air filters are made with either a foal element or paper, while oiled filters are designed with high-flow cotton. Once the dry filters get contaminated with dirt, they become hard to clean. therefore, they’re not reusable. When it comes to oiled filters, they’re easy to clean and maintained.

2. Carb Approval
Before buying an air filter, check if it’s compliant with your state policies.

3. Timely Maintenance
The air intake needs regular clean up intervals for prolonged life. If you're driving in a muddy or dusty area, then you require more inspections. More so, have a regular look on tubing and clamps to prevent fitment issues and ensure proper routing.

4. Water Intake
Always prevent entering of water and other fluids in the air intake system. water ingestion will damage the system and damage the engine. To avoid this, get a system that's fitted with a bypass valve.

What are the Indicators of Bad or faulty cold Air Intake?

Cold air intake filters directly feed air into the engine. Therefore, if the system is faulted, then it can lead to issues with driving. Usually, a faulty cold air intake will have some symptoms. They include;

Reduction in Engine Performance

Once the engine's performance decline, then this is an indication that the air filter is not working properly. A clogged air intake system can cause a reduction in fuel efficacy, power, and acceleration.

Excessively High Idle

An excessively high or surging idle is an indication of a vacuum leak. Filters with vacuum ports are designed to accommodate the manufacturers' vacuum routing. Once the port breaks, it will lead to vacuum lead, causing surging or high idle.

Check Engine Lights

Once you notice an illuminated engine light is a symptom of a faulty air filter. Issues like faulty sensors or vacuum leaks are some of the reasons why the check light can be set off. 

Customer Reviews

Here are some comments from customers:

Bryan Nelson

“Installed on 2015 Ram 2500 w/ 6.7 Cummins. Easily the most difficult and time-consuming intake I have ever installed. Took about 2 hours; part of the issue is the height of the truck. Instructions are very elaborate and easy to read. The pictures were great also. It looks and sounds great. Turbo is easily heard.”

Always Fishing

“First, this cold air intake is a lot easier to put in than many people make it out to be. It took me just over an hour to take out the old and put in the new. Second, my truck definitely breathes a lot easier than before. I can actually hear the turbo spool now. I have only put a couple of hundred miles on the truck since I installed the intake, so I cannot provide much in terms of performance. Fuel mileage did increase by about .5 miles per gallon.”


➢ How often should I replace my cold air intake filter?
