Engine air filters are important!
Size: 8.26" x 5.63" x 2.24"
Just like me and you breathing, your car performs better when it can breathe freely and cleanly.
My philosophy with an engine air filter is to replace with cheap and often. You can't control the quality of air coming into your system but you can control the filtering, so I'd rather replace the filter on an accelerated schedule with a cheap product than to invest into something more expensive and have it perform dirty for longer than it should.
For my Honda CRV 2024 Hybrid, this filter fits snuggly and performs well.
