I bought the Injen Cai for $210 shipped from crossover auto, Ive got 300 miles on it and no problems. It has a great finish to it, the silicone reducer is nice, the filter is basically a K&N, stickers, and great instructions for an easy installation. I had a K&n panel filter with 1 large hole in my airbox, I got some sound with that, but honestly this intake blows it away, its very loud, and very responsive. In comparison to the MS intake I really dont think the added water sheild is needed because everything is surrounded by factory sheilds. I like how the Injen is 1 peice vs MS 2 peices. The only difference people try to claim the Ms intake is better becuase it comes with a dry filter, vs the oiled filter with the Injen. Which people have been running oiled K&n filters for a long time with no problems, just some people have had previous problems with MAS going bad due to the oil. Which I dont is a problem on our cars if the filter is oiled properly and isnt right next to the sensor, which we have a good 2 feet between it. For the price quality and performance I honestly dont think there is a better intake out for the MS3 than the Injen. Honestly I wouldnt even compare the Ms, I would more decide on the CPe vs Injen, cpe is a good company, and so is Injen. I got the Injen though and am very happy with it.
I dont think there is a better mod out for our cars for 250, an intake is def worth it.
