I immediately felt the power on my 300+ HP go up to another level. It also felt like it accelerated smoothly. My car can breathe!!

K&N Filter for 2005 Saab 9-3 and 2010 Nissan Cube

I have seen the ads and thought about buying a K&N filter for years. Finally I pulled the trigger and shame on me for not doing it earlier. Installing the filters was a breeze in both cars and even a novice with a ratchet set (like me) can do it. The throttle response in both cars is noticeable and the Saab sounds much better as well. Do you self a favor and buy one today.

It is my fifth K&N filter

If they weren't the best I wouldn't continue to purchase them. I am very pleased with the performance of this product.

I have one in all family cars/trucks as you earn money back over time not having to buy air filters As for performance not earth shattering in my N/A 4 banger until I go WOT. In Saab, with turbo, pretty awesome. More sound, off the line, but WOT is whole new car. I recommend simply to save money on new filters. Each engine will behave differently. Only problem is I wish the filter was thicker. Oil seems to get black quicker? That's ok I change oil 3 to 5000 miles.

Quality made, but lacking some features...

I've always had good luck with K&N filters, whether as a direct replacement or for an all out performance application. This one was no different. An immediate change in turbo response was noticed, despite the car previously having a very clean paper filter. K&Ns are always good investments, if just for the ability to clean them, but this one also offered a noticeable performance gain.

at great.
