Cabin Air Filter Box for Tesla Model Y 2021 | 1495167-96-B

Product Overview

Key Specifications

Core Functions & Benefits

• Airflow Optimization: The box’s internal geometry is engineered to direct incoming air evenly through the filter, maximizing contact with filtration media (whether standard or HEPA). This ensures no bypass airflow, so 100% of incoming air is filtered.
• Leak-Proof Seal: Foam gaskets along the edges create an airtight barrier between the box and the vehicle’s ventilation system. This prevents unfiltered air—laden with dust, pollen, or exhaust fumes—from seeping into the cabin, safeguarding air quality.
• Structural Protection: The durable ABS housing shields the air filter from damage caused by vibration, temperature fluctuations, or accidental impacts during maintenance. It also prevents filter material from tearing or shifting, which could compromise filtration.
• Easy Maintenance Access: Designed with a user-friendly access panel (secured by quick-release clips), the box allows for straightforward filter replacement—no special tools required, aligning with Tesla’s emphasis on DIY-friendly upkeep.

Signs It Needs Replacement

• Air Leakage: If you notice musty odors, increased dust in the cabin, or uneven airflow from vents, it may indicate a cracked box or worn gaskets allowing unfiltered air to bypass the filter.
• Visible Damage: Cracks, warping, or broken clips on the box (often caused by improper filter installation or age) can disrupt the seal and structural integrity.
• Filter Misalignment: A damaged box may fail to hold the filter securely, leading to shifting that creates gaps for unfiltered air.
• Reduced Airflow: A warped or blocked box (due to debris buildup or damage) can restrict airflow, making the HVAC system work harder and reducing efficiency.

Installation Guidelines

• DIY-Friendly Process: No professional tools needed—follow these steps:
  1. Locate the cabin air filter access panel (typically behind the glove box or under the dashboard on the passenger side; refer to your Model Y owner’s manual for exact placement).
  2. Remove the old filter by releasing the access panel clips.
  3. If replacing the entire box, unscrew the 4 mounting bolts (8mm socket) and disconnect any retaining clips.
  4. Position the new 1495167-96-B box, ensuring foam gaskets align with the ventilation housing. Secure with bolts (torque to 3 Nm) and snap clips.
  5. Insert a new cabin air filter into the box, close the access panel, and test airflow to confirm proper installation.
• Pro Tip: Replace the box whenever you notice gasket wear or structural damage—pair it with a new OEM filter (e.g., Tesla part 1495167-00-A) for optimal performance.
