Jeep Wrangler TJ Cold Air Intake
Jeep Wrangler (TJ) Cold Air Intake Maintenance Tips
The cold air intake system can, theoretically, increase the efficiency of the Jeep Wrangler (TJ) engine, but it will only do so if it is maintained regularly. Cold air intake system components, with the air filter in particular, are sensitive to contaminants and will not be able to allow the optimum amount of air onto the engine.
Maintaining the Jeep Wrangler (TJ) cold air intake system is not that difficult and only takes less than half a day. In this guide, we'll share some tips on how to clean and maintain the cold air intake on your truck:
- Regularly clean the air filter.
The heart of the cold air intake system, the air filter traps dust and other particulates to keep them from entering the combustion chamber. But these particulates will build over time and must be removed to prevent the filter from clogging up. Most filters tend to go up to 50,000 miles before cleaning is required, but if the filter screens are no longer visible because of dirt then it must be cleaned regardless of what the odometer says.
To clean the air filter, you will need to use special air filter cleaner, often found in auto parts stores and comes in a spray bottle. Spray both sides of the filter and let the cleaner soak for 10 minutes before rinsing with water. If the filter is particularly grimy, you may need to repeat the process.
- Lubricate with oil.
Once the filter is cleaned, it is recommended to coat the filter with air filter oil recommended by the manufacturer. Air filter oil is essential as it helps keep the filter media from drying out and making it more effective in trapping dirt and microscopic particles from the air. Make sure to spray the oil evenly along the crown of each pleat and let it wick for 20 minutes.
- Don't forget to check for rust.
Metal components of the cold air intake, such as but not limited to clamps, pipes, bolts, and other hardware, are also vulnerable to rust and will corrode easily. So take the time to check these components for rust, and clean them as necessary. Minor rust spots can usually fixed by rubbing the affected area with a cloth soaked in vinegar, although more serious cases will need replacement of the affected component.
