Excellent fit and great quality”
This filter fit perfectly and was very easy to install. The quality feels solid, and it made an immediate difference in air flow. It’s a reliable replacement at a much better price than the dealer. I’ll definitely be buying this brand again for future changes.

Good filter
Pretty thick. May restrict airflow a little bit but it's a good filter.
