The air filter is pretty good, I only have a few issues with it. 1. Not really with the filter, but with Edelbrock, they're supposed to make their products in the USA, but instead on mine there was a large 'Made in Taiwan' label. 2. The plugs for the bottom pcv holes don't fit and broke when I tried to put them in, I had to use tape to close them. 3. The wire that holds everything together is very thin and easy to bend. However, it's very good when you have limited space, easy to disassemble if needed, and easy to clean. Overall, I am happy with the purchase.
