I just install a k&n intake on me 2005 mr but now i have a litttle problem when i put the pedal all the way to the floor and when i get somewhere between 5000 and 6000 rpms it bog for a faction of a second and then kicks back in does anyone know what is wrong

 

Im guessing this is your only mod..? If you do a search you'll find more than enough information, but on most evo's the cars mass air doesnt read right with the intake and gives you problems. Like alot of other people I recommend going to stock until you get a flash/tune, otherwise you will have the same problems.
