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.

  • Installation Tips for the Jeep Wrangler (TJ) Cold Air Intake

    A cold air intake is an aftermarket product toes the line between increased engine performance and easy installation. While it doesn't provide as much of a power boost than the turbocharger to your Jeep Wrangler (TJ), it also does not require extensive modification of the engine.

    If you are planning on installing a Jeep Wrangler (TJ) cold air intake on your own, be sure to follow the instruction manual that came with the intake. An improperly installed intake will lead to zero or even a negative effect to your engine's performance. In this guide, we'll share some additional tips you can use when installing the air intake to your truck's engine.

    Tip #1: Prep the car.

    This involves allowing the engine to cool down, engaging the emergency brake, and putting chocks on the rear wheels. We also recommend unplugging the car battery as a precautionary measure against electric shock. Disconnect the negative terminal, which is often painted black, first followed by the red positive terminal.

    Tip #2: Pre-fit the intake.

    You're probably stoked into bolting that new cold air intake onto your ride, but pre-fitting the intake ensures that it actually fits and works properly with your engine.

    With the old intake removed, slot in the new intake and try to attach the hose clamp. The clamp should be able to slide in and be tightened without much difficulty. Next, check if the intake does not block the hood from closing properly. Finally, check the intake by moving it from side to side. If the intake's tubes and other parts easily strike other objects inside the engine, try and tighten the bolts until it is secure. Continue making adjustments until the air intake is perfectly secured in place.

    Tip #3: Don't throw away the old intake just yet.

    If your old air intake is still in working condition, we recommend storing it as a backup in case you encounter problems with your new cold air intake later on. Keep in mind that cold air intakes are aftermarket products that may not comply with OEM specifications, so compatibility and performance issues are a likely occurrence.
