Review on 🚀 Spearhead Max Thrust MT-741: Ultimate Performance Engine Air Filter for All Mileage Vehicles by Jarrett Young

At first I didn't expect any change in performance or mileage. And I didn't see any change in either of them. I replaced the OEM filter with at least 70,000 miles. The filter I pulled out looked a little used but certainly wasn't clogged or looking very dirty. I think the difference in performance could only be noticed when the old filter was badly clogged. There might be a slight difference with the new filter but not enough for me to notice and the mpg was the same. I don't think anyone should change the filter or fit a new air intake system if they want a performance boost, it's very unlikely there will be a noticeable difference. But if your old filter is clogged, be sure to change it!
