📋 Before You Begin

• Open the hood and let the engine cool for 15–30 minutes if it was just running.
• Take a quick photo of the airbox and intake tube routing so it goes back the same way.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing (airbox)

• Use a flashlight to find the large black plastic box connected to the intake tube.
• On your Grand Cherokee, it’s in the engine bay and has either metal latches (clips) or several screws around the lid.

Step 2: Free up the airbox lid (two common setups)

• If your airbox uses metal spring clips:
  • Release the clips by hand, or gently pry with a flathead screwdriver (medium) if they’re tight.
• If your airbox lid uses screws:
  • Remove/loosen the lid fasteners using a Torx T25 driver (some are quarter-turn captive) or an 8mm nut driver depending on what you see.

Step 3: Loosen the intake tube clamp (only if the lid won’t lift cleanly)

• Loosen the hose clamp at the airbox outlet using an 8mm nut driver or flathead screwdriver (medium).
• Tip: Only loosen enough to lift the lid.

Step 4: Lift the airbox lid and remove the old filter

• Carefully lift the lid upward; don’t force it—look for any missed clip/screw.
• Pull the old air filter straight out by hand.
• Use a clean shop rag to wipe out loose dust from the airbox lower half (do not push debris into the intake opening).

Step 5: Install the new air filter correctly

• Place the new filter into the airbox the same direction the old one came out.
• Make sure the filter’s sealing edge sits flat all the way around (no corners folded).
• Tip: If it doesn’t sit flat, the lid won’t seal.

Step 6: Refit and secure the airbox lid

• Lower the lid straight down so it aligns with the lower airbox.
• Re-engage the metal clips by hand, OR tighten the lid fasteners using a Torx T25 driver / 8mm nut driver.
• If you loosened the intake clamp, tighten it using an 8mm nut driver or flathead screwdriver (medium) (snug, do not over-tighten).

Step 7: Final check

• Run your fingers around the lid seam to confirm it’s evenly closed.
• Use a flashlight to confirm no tools/rags are left in the engine bay.

✅ After Repair

• Start your Grand Cherokee and let it idle for 30–60 seconds.
• Listen for a whistling/hissing sound near the airbox (can mean the lid or clamp isn’t sealed).
• If you notice any check engine light after the job, re-check that the airbox lid is fully seated and the intake clamp is tight.
