Installed my new AA Green filter today and I am very happy with it.
First thing i noticed is that the engine sounds alot better, def. sounds like it can breathe better. Performance wise I could say that the car felt a bit more responsive when i got on the gas. Butt dyno says there is good performance increase. My previous MS air filter was only used about 7K miles and I would say that AA feels much better than the MS did in the beginning. I will def. be getting AA in the future.
The construction of the filter was really good as well, fit like a glove installed. No rattles or noise.
