Jeep Grand Cherokee Cold Air Intake

Tips on Identifying Jeep Grand Cherokee Cold Air Intake Problems

Your sporty Jeep Grand Cherokee will certainly perform even sportier with a cold air intake. Its main function is to cool the air before sending it off to the engine. The cold air, which expands when heated, is used to energize the combustion process by increasing the concentration of oxygen. In this process, the cold air brings about better burning of the fuel, thereby improving fuel efficiency. Unfortunately, there are a number of problems that can be encountered with a Jeep Grand Cherokee cold air intake. Take a look at the following symptoms to help you determine your Jeep's cold air intake situation.

Abnormal noise

If you hear any weird noises coming from your air intake, check the air intake for any blockages or anything that may be impeding the air passage. Check also the air filter as it may already be too dirty. If it is, you can opt to clean it or wash it altogether.

Less horsepower or lower fuel efficiency

Check the filter to see whether it is clogged or dirty. The purpose of the cold air intake is to increase the concentration of oxygen for a better fuel consumption. But if the filter is clogged, the purpose is defeated and is even reversed! If it is already too dirty to be cleaned, you will need to replace it with a new one.

Low revs

Inspect the wiring connections for loose plugs or clips. Loose connections cause the air sensor to make inaccurate air measurements, which results in seemingly low revs.

High RPMs

See to it that the hose clamps seal the intake tight. When seals become loose, small particles can easily get sucked into the air intake through the gaps. If this happens, you will experience higher RPMs than usual, in addition to a loud noise coming from under the hood. Furthermore, these particles can also become the reason for a damaged engine combustion chamber.

Other intake malfunctions

Some aftermarket cold air intakes usually encounter problems like the fittings coming loose. This creates leaks and other malfunctions, which may cause and extreme change in temperature. Make sure to tighten the fittings regularly to avoid this problem.

  • Getting the Most Out of Your Jeep Grand Cherokee Cold Air Intake

    Like many other car parts and accessories, your Jeep Grand Cherokee cold air intake needs to undergo some maintenance procedure every now and then to keep it in the best condition. Since you bought the part to improve your car's performance by cooling the air before driving it to the engine, you want to keep it that way as long as possible. Here are some measures you can perform to get the most out of it:

    • Clean the air filter regularly.
    • You can clean the filter by simply tapping it lightly against any solid surface. You may also opt to wash it with a filter cleaner to thoroughly remove the dust that may be blocking the air passage. You can do this by soaking the filter for 15 minutes in a gallon of water mixed with some liquid dishwashing detergent. Do this procedure twice to make sure the filter is clean for it to be able to deliver exemplary mileage-increasing performance. Then, shake the filter dry and make sure you apply air filter oil on it to prolong its life as well. This keeps it in top shape.
    • Secure the clamps, seals, and fittings.
    • Check also if any of the clamps, pipes, and hoses have been infected by any corrosion. If left unattended, they may snap loose, leaving the intake and other components dangling or displaced. Aside from this, if the cold air intake gets accidentally disconnected, unclean, warm air will enter the engine. This will bring about a sudden change in temperature as well as a lot of contaminants into the engine. To prevent all this, take care that everything is sealed correctly and properly.
    • Use a heat shield.
    • Using a heat shield with the cold air intake will further reinforce the intake's purpose of delivering cold air into the combustion chamber. The heat shield keeps the heat coming from the exhaust system away, thereby adding 3 or 4 more hp.
    Additional tipBefore actually getting a cold air intake for your vehicle, make sure you know a thing or two about different brands and be best informed. Getting a 'nameless' cold air intake is quite equivalent to just tossing your money in a dumpster, because such intakes use up a lot more money in repairs and maintenance than the more-costly-yet-of-higher-quality ones.
