To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Bought this for my truck (2000 GMC SIERRA 1500 4x4 5.3L). The housing was an exact match but the four (4) screws that secure the lid did not match OEM. The new screws looked like beefed up drywall screws and fully unscrew from the lid. The OEM screws were designed so that once the lid screws were loosened, they stayed attached to the lid. These beefed up drywall screws can easily be lost while doing routine maintenance on the air filter. Luckily I was able to install the OEM screws onto the new lid.
