Review on πŸ”΄ Red High Flow Drop-in Air Filter Replacement for BMW 325i / 328i – Reusable and Washable for Enhanced Compatibility by Alex Webster

Revainrating 5 out of 5

K&N Carbon Copy is three times cheaper. EXCELLENT choice.

I've always had K&N drop-in filters on Altima, Versa (unfortunately yes. I just bought a house.) Lexus LS400, Audi A4, Subaru Impreza and now I've upgraded a BMW 330i Wagon ". I don't like air intake kits because that's what kids wear, and it looks underage (I had one in my '96 Civic in 1998). The plug-in filter is much better and keeps the engine compartment clean. I was SHOCKED with them because their build quality is an exact replica of K&N. Actually, I'm making a YouTube video about it. that's how i liked it. And yes you get an HP boost, expect a realistic 2-5 HP boost. That's the same aftermarket cone air intake. Always remember that an air filter is only one performance enhancing component. But getting it is a good start.

Pros
  • Durable Test Results
Cons
  • Safety
