Review on 🔴 AEM 21-203DK Universal DryFlow Clamp-On Air Filter: Round Tapered; 3 in (76 mm) Flange - High Performance Red Filter for Improved Airflow by Chad Mills

The product had better durability but is a bit more expensive than my Neuspeed. I have a VW Neuspeed intake and the filter is very dirty. I figured I'd just skip the cleaning and buy the AEM I've used on cars in the past. I measured my air filter and the measurements were similar (not exact). This is where my problem came in: the AEM filter was half an inch too long for the disassembled CAI box for my car. I couldn't install it so unfortunately I had to send it back. another K&N filter on another machine and I see the porosity is about the same. You can collect many kilometers. Value for money is probably a bone of contention when it comes to ROI. K&N station wagons are $40 so I don't know why they're a bit more expensive.
