Installed on my 2002 325i e46

Easy to install and greatly improved both sound and response. There's also slightly higher performance. Can't wait to pair it with some headlines! Good product! Highly recommended!

Pros
  • Easy to use
Cons
  • Expensive

Good performance Addition to my 2004 BMW 325i

I have used K&N products in the past so I was confident of the quality. The building instructions were excellent, as was searching the K&N website online. After installing it, I noticed a slight increase in performance and a quicker response to throttling - just what I was hoping for! Revain also had the lowest price, excluding taxes and shipping costs.

Pros
  • Complete kit
Cons
  • poorly thought out

Fast delivery, quick installation,

Arrived quickly via Prime. Installed in under an hour sounds great as it looks great, we all know performance is minimal but I'm happy with it. Be careful when tightening the intake boots as they can break very easily. I ended up snapping my F-connector for the two vacuum hoses that attach to the upper intake boot trying to remove them. So be careful again, the white cast grease and flat head will get the way. Installed on my 325ci 2001.

Pros
  • Best
Cons
  • Not sure

Very good! On 325i 2002

I bought this in June and wanted to wait a bit to actually test it. 6 months with it and I'm satisfied! It makes a nice raspy growl when revving past 3000 rpm. No annoying whine like the gaudy cheap CAI systems on the market. Fuel consumption, I can't honestly say, has changed. I've gone from about 17.9mpg to 18.1mpg in the time I've had it, but I also drive it fairly aggressively and in very bad traffic. The car definitely has better acceleration but is noticeably different from what it was…

Pros
  • everything is fine!
Cons
  • Easy maintainability

2003 BMW 325i with air intake

2003 BMW 325i Installation: Very easy, make sure you have European car plugs for easy installation. Lots of youtube videos on how to install these filters. I also recommend buying a MAF sensor cleaner and using it during installation. Performance: The air intake makes a very pleasant noise when accelerating. At low speeds there is a knock, but after 30 km / h it is no longer heard. I haven't been able to tell if MPG is getting any better. About 2 weeks after installing this product, I soon…

Pros
  • Free for educational purposes
Cons
  • Big and bulky

Attention, the panties can fall off when driving past!

Probably lied about the mileage. Just because I'm speeding around town with the windows down to listen to that sweet, sweet 3km deep rumble followed by a burst of air that allows for better throttle response. When I hit the freeway I notice a jump in mpg, not much but over time I'm sure it saves money. I also notice that I don't have to downshift as often when accelerating. He's confident in the gear I'm in. So it's easier on your transmission for the average driver. I hooked it up to my obd2…

Pros
  • Great price
Cons
  • Approximately
