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.
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.
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.
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.
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.
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.
