Just to add a little info from myself...
I had the MTC intake kit which i was impressed with, definitely felt a slight difference in pull and the sound was great! I was getting long term fuel trim of 5.1% (which wasn't bad considering other people with MTC's were alot higher and i didn't do that pipe mod thing to it)
I got Revo stage 1 on the car and bought the Revo intake to match. I thought the MTC intake was loud but this Revo kit wants to whoosh and chatter all day long! I love it, there's a noticeable difference between this and the MTC in the mid to top end of the rev range and it pulls much harder. The 1 piece pipework makes all the difference with this kit and all those joins in the MTC intake just restricts it. I am getting long term fuel trim of 3.1%
After this experience i've learnt to save and spend on the best. If you want to get the most out of your car from an intake, then go REV
