Goodbye to paper filters! Excellent upgrade when combined with bigger air inlet sold by genuinesaab.com.
I had never heard my turbo spooling up on 4th and 5th gears but now with these two items together I can hear the turbo on the highway! I'm looking to do a Nordic Stage 3 upgrade in the near future and this is a great little upgrade in the meantime! Definitely recommended but you really must buy the bigger inlet to get any improvement.
