Hey guys, there were no threads that I could find on any forums with photos or a step by step method to remove the resonator and baffle in the airbox, so I figured id show first timer's how to do it for the MPS 6 (without the need to remove the bumper)
What you need:
*Socket set with 14mm socket and a long extension
*Phillips head screwdriver (pref a short stubby one)
*Car jack
*Cling wrap or something to seal the intake off (DONT START CAR WITH THIS)
*About an hour free
************************************************** ********
Step 1 - Pop the hood, jack up car on the passenger side (or for the Yanks, your drivers side)
************************************************** ********
Step 2 - Loosen the connection between the intake tube and the airbox, put cling wrap around the rubber intake tube to stop shit getting in, pop the 4 clips which hold the top (AFM) and bottom (Filter) side of the airbox together and lift and turn this to the back (rest it on your battery - no need to unclip the AFM cables)
************************************************** ********
Step 3 - Take out air filter and put it to the side. Now you will be looking at the bottom of the air box with plastic crap everywhere. Grabbing this with two hands, carefully start to pull upwards and to the guard and the 3 rubber grommets underneath the box will give and pop off leaving it looking like this.
************************************************** ********
Step 4 - Now you should have the bottom plastic airbox in your hands, around it will be a baffle tube which looks like an S-Bend plastiky thing that hangs off it, pop this off and chuck it away. Then there will be some more plastic (a baffle) sitting firmly inside the bottom of your airbox, this is clipped in all around the outside. To remove this, grab a flat screwdriver and start un-clipping this around the box and from underneath (you should see the tabs), you will find all of the tabs are pretty easy to undo except for the two bigger ones on either side of the box, once you get to this point your gonna want to get your hand in and under the plastic baffle from the inside and pull upwards putting pressure on it, while pushing down on the outside and trying to pop one of those side tabs in, if you do this correctly, one of them will pop and you will need to rip it out at the other one (AFAIK it had to be broken when I removed it - meh). Good stuff, first section is done, leave this bottom airbox section to the side for later when you will put it back in.
